@undecidedMF I hate these kind of videos. hyping up to the question too many times and diverting to another tangent each time and also to insert the shameless plug..
Cobalt doesn’t come from Africa in spite of the terrible working conditions. It is predominantly mined there BECAUSE of those conditions. Many countries including Canada have access to as much cobalt but safety restrictions and much higher wages make African sources much more lucrative. In fact, there is a mining town in Canada named Cobalt after this and other rare earths that used to be mined there. The resources still exist. It’s just cheaper to dig elsewhere.
Canada has by far the largest oil reserve in the world but is like 5th in oil production despite having the USA as a neighbor being able to pipe the oil down there and fuel the industry of two big economies. It's actually ridiculous how little Canada is utilizing it's resources it should be one of the richest countries in the world. Instead the citizens can't even buy groceries lol.
The US is a net exporter now, so Canada would do better to export elsewhere. But if tar sands are included, they are likely more expensive than most other options
I realize this sounds a bit sappy, but listening to your content always gives me hope that one day, humanity will find a way to balance our energy needs while maintaining environmental stewardship. These advances aren't game changers but necessary steps toward better technology. Another outstanding job. Thank you, Matt!
of course, we will reach that point. so long as government don't ruin the economy by trying to force energy system down a path before the technology is ready for it to be viable. They've already shown they are willing to do it with all the electric car mandates that are never going to be met.
This is part of it, but the only way to balance the energy needs and taking care of the environment is human-centered economic degrowth. Otherwise, we would need so much renewables with the continuous growth of energy demand inherent to the current system that we will demise much of ecosystems through critical minerals mining and energy farms.
Point of clarification: Rolls-Royce Motor Cars Limited was created by BMW in 1998 and is completely unaffiliated with Rolls-Royce PLC, the owner of Rolls-Royce Power Systems and the MTU brand. Rolls-Royce hasn't made cars since its bankruptcy in 1971. BMW licences the brand and logo, but the cars share no lineage with the cars made prior to Rolls-Royce's bankruptcy.
The car lineage is via Bentley. The Crewe factory has been making cars since 1946 and continues to do so, even though it is now owned by VW. en.wikipedia.org/wiki/Bentley_Crewe
Even companies with traceable lineages have evolved to treat the automobiles they produce as a side effect to generating revenue from subscription services. We have BMW attempting to coerce customers to pay for heated seats, or GMC pushing Onstar, or Mercedes-Benz hawking driver assistance, all the while selling driver data.
@@catsupchutneyWe’re getting side tracked, but: 1. Capitalist companies didn’t suddenly start following capitalist ideas. They’ve always been money first, because without money they fail. 2. BMW trialed heated seats as a subscription in exactly one country based on user feedback. The trial didn’t pan out, and they canceled all roll outs. 3. Economics of scale have meant that features are often technically included in a car, and not turned on. You (or the original owner) may not have optioned heated seats, but the seat may have the coils. Find a button and attach it to the wires, and voila! Heated seats!
People are complaining that battery cell tech never makes it to market. It can take years to get from the lab to commercial penetration. 1996: John Goodenough and his team at the University of Texas at Austin discovered the LFP cathode material. Pattent was granted in 1999. The global LFP share increased to 34% in 2022. November 2023, LFP batteries captured 31% of the passenger EV battery market. The forecast is to reach 39% by 2024. In China, LFP batteries now make up over 50% of the EV battery market in GWh term. Interest in battery cells has increased somewhat and perhaps that will accelerate the required time.
Every company offers shorter warranties when they can because of misuse and unforseen circumstances. They also know batteries/systems will be different in 10yrs and don't wanna have to keep repair parts forever
@@veganpotterthevegan Every company in the EU has to keep spare parts for at least 7 years after the last sale, so anything less than that is lack of confidence in the product.
You beat me to this comment. I was thinking the same and wouldn't put it past companies to do this. I don't think Matt mentioned what the degradation would normally be in 5 years. If it's only like 5-10%, you just make the batteries a little bigger and hide their extra capacity as headroom to make up for the degradation.
They are probably achieving having no capacity degradation in the first 5 years by cheating a little. And the 15000 cycles quoted hints at exactly that. The capacity degradation of LFPs over 5000 full cycles should be about 20%. However, if you make the capacity 20% larger to start with but never allow each cell to charge to more than about 85% then you should only see about 5% capacity degradation over 5000 cycles. So after 15000 cycles, or 5 years, you should effectively see no actual degradation on the quoted capacity.
It should be noted that LFP cells already easily outlast any power electronics associated with them and have for a long time. So, this is good progress, but it isn't earth-shattering. Also, as with most ESS manufacturers, CATL likely builds some buffer room in their capacity guarantees verses the actual capacity of their cells. Their ESS systems (and certainly their marketing) are likely programmed only to the capacity guarantee. The cells probably do degrade (but LFP degrades very slowly anyway)... but its hidden for a time by the buffer. In anycase, this is almost a moot point. LFP cells have such low degradation that the actual cycling is almost irrelevant... Calendar aging does more damage. And as I've mentioned several times, the power electronics associated with these packs will fail long, long before the cells do. Even with regular LFP cells. As a maintenance item, the power electronics represent a much bigger fish. -Matt
It's interesting how fast things move. While solid state seems like the ultimate way to achieve potential airplanes, etc on electric, I feel like sodium ion is going to be the biggest growth area soon. Natron Energy is building a 2nd plant in the USA and while it may not work well for cars yet, the storage capacity and price seems like a win win for everyone. Though I have a few LFP cells for a home DIY battery, I am now hoping the salt battery cells start showing up to build longer lasting storage. That Natron's cells supposedly do 50,000 cycles and full charge in 12 minutes is damn impressive. Thats a lifetime battery right now for most who could buy one (though I dont think they are for homes yet). I could see however if they can increase the capacity without weight in the next couple years, we could see affordable 25K EVs with 500+ mile ranges.. maybe not 0 to 60 in 4 seconds or so.. but I would argue most people would want a 500 to 1000 mile range on a 12 min charge over a couple seconds faster to 60mph. Especially if it could also last 20,000 to 50,000 cycles making it a 100 year+ battery.
IF EVs are going to be able to get 500+ miles, in any weather, without degrading, in about 2 minutes.... I'll just wait a couple more years for that then and keep my gas car meanwhile which already does all this.
Reminds me of the mid-70s and the oil crisis when Popular Science had several articles about the latest in batteries for the upcoming surge in EVs. For cars, rapid recharge was right up there with energy density. The two “front-runners” I remember were one using molten sulphur as the electrolyte - a bit of a concern in an accident - and an “air-aluminum” based setup. This latter one “consumed” aluminum sheets so recharge just required replacing the sheets and removing the oxide for electrolysis back to aluminum but was extremely sensitive to CO2 in the air which was already too high back then
I'm a BESS engineer working with all of these systems mentioned in the video and many more. I'm under NDA for all of these so can't say anything that's not public but all I can say there is a lot coming and we are just at the start.
Well, NDA notwithstanding, can you give us some little clues. Like .. When will we see some competition to T's Powerwall-3? Same spec, cheaper? When will Na hit the retail market for home microgrid?
@@jonb5493 Haha, you could get sued for breaking an NDA, but here's something public. I usually work with large-scale systems, but I know LG is coming out with a smaller wall battery that uses the same LFP cell as their large-scale storage.
Somewhat, in the case of a fuel-cell such water self assembly needs a little helping hand from a platinum catalyst to break gasseous dihydrogen into hydrogen to help create water by reaction with oxygen.
Absolutely fascinating video! The TENER battery's potential to maintain performance for five years without degradation could be a game-changer for the EV industry. As we push for more sustainable energy solutions, innovations like this are crucial for enhancing the efficiency of electric vehicles and renewable energy systems. I'm excited to see how this technology evolves and its impact on the future of energy storage. Thanks for sharing this insightful update!
15k cycles/(365 cycles/day)=41 years, no degradation in the first 5 years means nothing. Also, there's no such thing as zero degradation. You just provide more over provisioning and by the time it degrades to its nominal value, the outside world sees zero degradation. Also, 15k cycles is not absurd even using existing technology. A 2k cycle rated cell (at 100% cycle depth to 80% capacity) can cycle 15k easily at 70% cycle depth at 50% remaining capacity and 2x the internal resistance (still quite useful for grid level storage). CATL did make technical breakthroughs, but the marketing material is certainly over-hyping them.
@@bskull3232Yeah, I don't see the hype for "zero" degradation. It could be nice, but not the deciding factor. LFPs can already last more than a decade with minimal degradation and it's not like they stop working past the rated cycles. Just like with solar panels. Price reductions are far more impactful. You could probably buy better batteries at less than half the price before the end of its rated cycles.
I usually listen to video in English but today I heard it in Hindi and being an ai voice apart from wrong numbers else was really good this will help people to break specific language barrier. Cheers
My principle in life is to live as you go with what technology is offering at that point in time. We currently have 2 fully battery EVs and enjoying them. If we live long enough and something else comes up, we go with the flow. It just seems like battery tech is changing daily and I can't even catch up what's out there anymore. As long as they are cheap and last 20 years, I'm good. Everything else is a bonus.
I think the biggest advancement would be an aftermarket solution to use a Tesla car. They are dirt cheap used for huge capacity. Just need the interface with your home electric grid.
@@jamesvandamme7786 I might not have an engineering degree, but I see a solution to this where you don't. I'm pretty sure you are assuming that someone won't disassemble the battery. If it's a Tesla car that's no longer useful (or more likely, that is getting you laughed at in public due to it's link with Elon), then you have a lot of components that make up a car, but can make up something else with some effort. Take apart the battery. The battery is made of a great many individual cells, and the idea with disassembling the battery is to liberate the cells and reassemble them into some number of series strings of cells that total up to no greater than 48v at full charge for any single series string. Commercial off-the-shelf pure-sine-wave inverters are able to accept that 48V input voltage and output more than enough 120/240v electrical power to support a typical American home. The only sticking point, and the part where your MSEE would come in handy, is that to ensure the safety of and prevent damage to the battery bank, a BMS and charging solution different from the one in the "standard" Tesla would be needed, due to the different electrical configuration of the battery cells. Since I have no such electrical engineering degree, I'd be looking for something that meets my needs that is available off-the-shelf, but a bespoke solution would be more easily tailored to fit the specific needs of the rearranged Tesla battery pack. What does all this accomplish? Well, at the very least, as far as the IEEE is concerned a battery pack that is 48v max is still "low voltage". So technically the only time I would be required to "mess with high voltage" would be when I disconnected and took apart the battery pack. I would of course be wearing proper PPE while I do that, I want to keep my eyes safe from the light produced by an electric arc (by not making one and by having PPE to protect my eyes if one DOES happen), and I want to stay alive (by wearing the properly rated rubber electrical gloves, I can pay for the right ones if it means I get to live despite maybe making a mistake, as humans do).

Check out Natron Energy's Sodium Ion battery solutions. They're supposedly shipping now. Rated for >50,000 cycles. They're marketed to industrial applications where they'd cycle multiple times per day, but if you apply it in a home solar energy storage solution, 50k once-daily cycles = 137 years! I'd say that's long enough for me!
There are a couple of batteries that should have unlimited life. Both have solved the dendrite problem. There is the Ambri liquid metal battery with three liquid horizontal layers. They us Calcium, antimony and a salt inbetween. All liquid so not dendrites. The second is the ZnBr battery from Redflow. It plates Zn onto horizontal shelves when charging and the Zn is removed during discharge. You make sure to completely discharge the batterie(s) from time to time which dissolves the Zn and hence any dendrites.
I use LFP battery from Aliexpress in my scooter, it's large and heavy ah hell (26kg), but the range(200km) is so worth it. It's bit overkill for city riding, but saves my ass when i forget to charge it.
Around 700eur including shipping if i remember correctly. It was a 60v 70Ah battery from "GTK" brand, they also go by the name "Shenzhen Fuxiang Technology" It took around 5 months to arrive.
@@alimfuzzy It's actually LFP, i checked the voltage, so it's safe. Either way i charge it in my storage shed since it's not practical to lug a 26kg box to 4th story apartmant without elevator.
I've had a LiFePo4 battery in my motorcycle for at least half a decade or longer, I forget when I bought it tbh. It's still going strong, in spite of annual multi-month winter storage. This is also the battery tech I'd use in a house battery (that I don't have yet).
I'm undecided... Do you have enough data to support that batteries are eco-friendly when compared to conventional ways of energy? Sounds like a dumb question, but extracting lithium seems like a dangerously pollution process. Could it be a good title to compare the different energy technologies in terms of pollution thru their lifetime?
every manufactures do damage on environemtn. EV and ICE both damage on nature when thsoe are manufactured. But during operation, EV do not produce any pollutions while ICE do produce so many pollutions from engines. Electricity from EV comes from powerplant that are being used in the past. We don't need to build new powerplant for EV. So in other word, EV uses electirc pwoer grid that existed in the past while ICE must pump out oil additionaly in order to operate. So ICE use extra energies that we don't have to when we use EV. So EV saves overal energy usages. At the end of lifespan of both EV and ICE, ICE are piled up on garbage field. While EV's batteries are extracted and re-use on ESS system for decades. So EV is much more environmentally friendly. This video says CATL makes special cells for ESS blah blah blah. Don't listen to it. Future ESS market will rely on re-using cells that are extracted from EVs. This is part of battery cell life cyle in future battery industry.
The Rolls Royce you talk about in the video is a completely separate company from the car manufacturer. Rolls-Royce Motor Cars Limited is owned by BMW. Rolls-Royce Holdings plc is a British multinational aerospace and defence company that is the world's second-largest maker of aircraft engines and has major businesses in the marine propulsion and energy sectors. The company also leads a consortium to build small nuclear reactors in the UK.
I'd like to get your take on the recent development with zinc-halide battery chemistry. My understanding is that similar to LFPs they're not as energy dense, but safer still and zinc is significantly more available than lithium. Everything I've seen indicated the intention to use them specifically for ESSs and grid support but I'm personally hoping to see home battery backups and UPS systems using it
LFP cells degradation is already so low for many use cases that the reduced degradation claimed (to be confirmed by how much) for CATL's product might not make that much of a difference in practice. The first thing that came to mind was that they'd guarantee a lack of degradation for 5 years is a capacity buffer. And it's probably what it will be anyway if they really want to guarantee NO degradation.
In a few years it's gonna seem crazy that we ever used something so flammable as lithium for this. You should do a video on Eos and their Z3 cubes. Non-flammable American-made zinc batteries.
The fact we still need more batteries just proves my point, that while power generation still need to increase, it doesnt have to increase what coal and other power sectors were trying to say that we needed to hit. The fact is we WASTE a ton of power everyday to nothing. Now that we have some way to store it we are seeing the need for power generation is actually dropping thus we're hitting to a point where renewables are even able to keep up with the base load power now just from a few hours of the day in the sun. Also while I loves to see more LFP - NA still to me seems like the clear winner when it comes to grid and home base power needs. If LFP is already doing this much work, cant wait to see what hybrid NALFP brings or even just raw NA (both sides of the battery) can bring next in terms of cost.
This is the thing. If we create a smart electric grid, everyone's electric car could be that dynamic storage. Charge them when there is excess, use the car batteries power for high demands. With it being smart, you can program your car to give or take as much as you need.
The biggest problem with Lithium-Iron-Phosphate batteries I've found is they REALLY don't like cold temperatures...every LIP battery I've looked at recently holds much more power than a standard Lead Acid battery of equal physical size, but all of them list the cut-off Temperature below which they will no longer accept a Charge is 4 C (39.2 F)...considering I live in Southern Ontario and it tends to be at or below 4 C from Late Sept. to Mid April, it means they're worthless to me...
@@rossallen738 True but the space in the case the heaters take reduces capacity and then the heaters themselves reduce apparent capacity to the point that they are effectively lead acid batteries in terms of actual sub-zero capacity, not worth it for powering my Mobility Scooter in the winter...
Great video! I never get tired of battery videos. I don't use enough electricity to get solar plus the grid here is from hydro power so my distant "Backwoods" dreams of an off grid system seem silly now.😊
Given that ESSs are principally there to get more use out of renewables, how many charge/discharge cycles per day are they expected to provide? I would have thought one or two would be all that is required, solar charges the ESS during the day and discharges at night. On that basis 15,000 cycles would last for 41 years without degradation! 5 years without degradation suggests 8 cycles or more per day. Thanks Matt for another brilliant video.
A few percentage points in degradation in years 0-5 can be easily compensated for by just making the battery a bit larger and heavier. For instance, if existing tech would result in 6% degradation after 5 years, just make the battery 6% larger to compensate, problem solved. What would make me more impressed about the technology is if it increases the total lifespan of the battery, allowing it to continue to be usable beyond 10 years or 20 years. That would be real progress.
LFP can already be cycled at 80% DoD once per day and still have 80% usable capacity after ~15 years. Which is still plenty useful. Calendar aging where it starts to really drop off its capacity is said to be at the 20-25 year mark. But there's not a lot of solid data there.
I just read that iron-air battery (reversible rust Battery) are being used as storage by Form Energy in Minnesota. It is said that solar connected to these batteries can be run a few days, making solar power always available. These iron-air batteries aren't nearly as efficient as LFP batteries; and I think they are currently more expensive. They are also bulkier that LFP batteries, so not optimal for automotive use. But what a concept!
What would be a real game changer would be a small, cheap, modular plug&play home battery that you can install easily with a small capacity to begin with and then upgrade over time.
18.000 people working in the R&D department of CATL, including 250 PhDs... let's expect quite fast quite many innovations for higher efficiencies, longer lifetimes, less material use, and lower costs
The cabinets are similar to what I had been helping manufacturer at Torus. They just opened a facility in salt lake to start their production line. Though they have been also making flywheels.
I have been on the fence adding energy storage to our Solar with the emerging battery tech. I think I'll be buying one of the new systems next year and hope it's everything we want it to be
Bio-mimicry will be the future of our technological design! Hearing that we're starting to incorporate natural solutions to our energy problem is so exciting
@Matt at 4:40 you mention 15k cycles = 5 years. It is 8 cycles per day. I guess these energy storage sites have 1 cycle per day (charge at daylight, discharge in the evening till dawn). Wth 1 cycle per day 15k cycles means 40years. How is that?
Ugh ... sorry for the confusion. I shouldn't have said "over" in that sentence. It should have been 15,000 cycles OR five years without signs of degradation. Also, keep in mind that batteries in some of these systems will be cycling multiple times per day. Many utility scale battery installations are doing energy arbitrage and storing and selling off energy to maximize cost savings for the utility as rates and use fluctuates. It's not always about carrying through an entire night.
My only question is, sure, it works flawlessly for the first 5 years.... after that does it fall completely apart? Does it degrade at the normal rate after that? What's the tradeoff?
I am guessing no. its just 5 years before there is any degradation. Even if it's the "normal rates," you are going to get another 5 years before there is any noticeable reduction in storage. If you plan on a 10% overhead, you can get 20 years before you start needed to replace, or add more cells to the system.
@spencer9392 if it's actually 5yrs with no degradation after so many cycles, it may have 10% degradation after 20yrs for all we know. But until these cells actually age under heavy use, we won't know. Lab tests for 5yrs of use over 1yr isn't gonna be the same thing as thousands of people using these batteries for 5yrs.
15 kw's does NOT cover the avg us household for 2 days. with wood heat in the winter we still use 30 kw's a day. the summer is more like 50-60kw's a day. you released this an hour ago.
He might have got it the wrong way around, apparently the avg is 30kWh per day. That said, except for the depths of winter I can cover almost our entire energy budget for most of the year with our solar output, I figure about a 10-15kWh battery would let us almost completely go grid power free. We don't have gas or other, I'd probably want some more panels if I had an electric car.
Sounds like you're well above the average. Average home electricity usage is 30 kWh/day. But agreed that 10-15 kWh of battery wont cover a house for 2 days unless the homeowner is very frugal with their energy usage.
@@suklee1400 kilowatt hours. It is a measure of the quantity of electricity. A kilowatt is a thousand watts. It costs from 8 cents to about 50 cents (USD) for a kilowatt hour if you are paying a utility.
5 years of no deg is impressive, but what is the practical lifespan of Tener ESS say to 15% degradation or 85% capacity left? And also is there a second hand market for "previously loved" ESS's?
is it not possible to build HUGE cappacitors ... maybe cheaper and easier, becouse they need to charge at daylight and give away heir power while it's dark.. would be a perfect job for fast cappacitors instead battery's that degrade by time
6.25 MWh is not an energy density, but an energy. An energy density could by energy per mass or energy per volume. What are the proper units that you meant to use? Thanks.
At night when the electrical power grid demand is low these Tesla battery packs are recharged. The benefit is your local power provider will need fewer power plants built to carry the heavy peak loads during the high power demand during the day. Resulting in a more efficient use of your power plants.
I have been looking into the new Tesla Aluminum Ion battery. This is supposed to last about 200 years with (if I remember correctly) and 50,000 cycles. It might be a good idea to at least look into this technology. If it is all true then an electric could go around 2000 miles between charges and is about 1/4 the cost of Lithium Ion batteries. Plus It is very safe and not subject to thermal run-away. Oh and last but least it can charge in only 10 minutes!
It says no degredation for the first 5 years. Which begs the question...why 5 years? What happens after 5 years? Is it better than the edison battery as far as longevity goes?
Presumably they only tested to a certain number of cycles before they stopped their testing. Then the cycle counts were used to establish a time period for decay. Anyways at some point they just shut down the test apparatus.
replying to your reply LOL - I am already subscribed, and comment a lot to improve YT rating for you. Now, expanding this topic, Forward Energy (you covered 2 years ago) are NOW installing iron/air battery in Grid , planned to run in 2028. Very exciting as iron/air potential is cost is 1/10 Lith. & and has very long discharge times (like days or weeks). Perfect Grid battery. Anyway Matt, maybe wait till 2028 see how they come up, although I see this as the missing ingredient in cost effective renewable grid proliferation.
Thank you Matt but the real questions to ask are : after the 5 years what is the balance of degradation for the following 5 years, expecting a life span of ??? It all boils down to the ROI. Lifespan is critical, recyclable etc many questions left unanswered.
Good points. On the recycling front these absolutely should be recyclable. There's a lot of really interesting movement in the battery recycling business too (LiCycle, Redwood Materials, Recyclico, etc.).
In any and every discussion of energy storage technology, the ability to FULLY RECYCLE the components needs to be mentioned. Whatever the degredation curve looks like, at end-of-life all the materials can be recycled into new batteries. This is why even gram of lithium needs to be captured from landfil NOW, like they're doing in Finland.
The battery likely has a 5 to 10 percent over capacity (reserve) that accounts for initial degradation. Many lfp cells niw have more capacity than advertised
I my not be the first with this but - isn't the simple way to give customers no degradation this: Oversize the battery pack and allow a large buffer when new, and gradually reduce the buffer electronically as the cells degrade like every other cell does? At first you give the user 85% of the true total capacity, and after 5 years you give them 95% of the lower (by then) true capacity.
I would like to see a price comparison for power and solar cost for a development like Homeowners Associations in Florida vs the same Kilwatt output and storage capacity. The cost, management, permitting and compliance are some benefits
China beats US in battery again? No way, impossible!!! And China beats US of A in solar, winds and nuclear energy?? Chinese are absolutely lying!!! And Chinese never killed any astronauts and built its own space station?? This MUST be CGI!
Just ask S. Korea...they just had multiple EV battery fires incidents from both a battery manufacturing plant (Chinese owned) and vehicles using batteries sourced from China.
PLEASE get the citizens of Vancouver to adopt heat pumps. Air conditioners are few and far between there, and our VRBO didn’t have one.

The TENER battery's five-year no-degradation promise is fascinating! It's great to see such innovations tackling long-standing issues in battery tech. What other applications do you foresee for this technology?
Most forms of stationary storage need to last 15-25 years to make economic sense. If the short-term pause on degradation has any detrimental effect on long-term reliability, it may be moot.
@@drillerdev4624 Modular battery systems for maintainability will definitely become a necessity: I cannot imagine throwing away literal tons of batteries due to single failed cells in the whole unit being sustainable. We're still ~10 years away from seeing how well the first wave of mainstream EVs and their batteries will age into retirement. I'm apprehending a nightmare of EVs getting scrapped prematurely due to single-cell failures and the inability to service battery packs in a safe, reliable and cost-effective manner.

A $12k DIY system has a payback of roughly 8 years just switching from a flat-rate plan to time-of-use + battery storage. Well within the longevity of an LFP system. Looking at ~15 years before they degrade down to 80% with current tech.
On cnevpost they say "Tener has a cycle life of more than 15,000, which is 1.7 times the current mainstream level, and will not decay in the first five years of its 20-year life expectancy, CATL said."
Hey Matt, I’m looking at going solar and was wondering which solar panel you would recommend and what battery would you recommend? Please provide pricing as well. Thank you
Is there any ESS that's using hydrogen for grid storage? It recently occurred to me that using renewables to create hydrogen via electrolysis could be a seriously effective way of storing energy, since I know that's one of the biggest hurdles there are.
No, theres some research, trial projects and industrial usage but no active scaled deployment of hydrogen storage compared to battery storage. The economics is against hydrogen in this case as batteries are cheaper (capital and operational costs), more effecient, take up less space and require less maintainence. Hydrogen is considered where there is a secondary use for the waste heat produced in the hydrogen generation, processing and conversion to electricty steps, such as industrial processes.
If a chemical change (like melting ice) stores power, then that chemical change in reverse (like freezing ice) releases power, and even if there are thermal losses of energy in that process, theoretically that process can be repeated infinitely as long as we have energy to input into the system. So theoretically, infinite cycle life is quite possible.
Melting ice is a phase change, not chemical change, but I see what you're getting at. Ice storage is already being used all over for commercial buildings. Charge up the ice tank at night when power rates are cheap and use the ice for cooling during the day. There may be some material that you can capture electricity with using phase change, but I don't know if any viable solutions exist yet.
Love your videos, but struggling with conceptualizing what energy/power capabilities a mega watt or even kilowatt have. I’d love to see more analogies when talking about batter capacity. For example, “this is a 15kW battery, which could power --- for -- amount of time.”
You may have already answered this question in a previous video, but I'm curious, can the component elements of these ESS systems be recycled and reused to manufacture new replacement systems. Thanks in advance...
The long-term problem with LFPs for grid energy storage is that they are the most sensitive to the price of lithium per kilowatt hour. This means that their success will ultimately lead to their failure as they consume larger amounts of lithium per kilowatt hour in production if demand for them skyrockets globally, the price of lithium will also sky rocket making them a less and less economic investment as they succeed.
In theory as prices increase new lithium sources would be exploited bringing the price back down. Although in the consumer world prices never go down that isn't the case for commodities. This can be seen at your local scrap yard. The value of lithium today is already spurring the development of new lithium mines. Like the one in Nevada iirc.
i am excited for all the new tricks for batteries and such.. I just hope they are not cheating. what i mean by cheating is making a battery 20% larger than they list and making it software limited so it only charges to the limit so as it degrades it still had rated capacity even if it decades.
5 years is a pretty good lifespan for zero degradation. Assuming they can still be used beyond that with some degradation being considered 'acceptable' up to a point; they should be really useful in getting some more stubborn folk on board. Still gonna have to do better though for the most stubborn folk. And I must admit, I kind of am one of them in my own way. I want to see mass scale rollout of lithium titanium batteries, based on what I have been learning about them. If they are actually as great as claimed and somewhat proven to this point as I understand; then there will be very little reason to not use them. If the Iron Phosphate versions help us get there, cool.
Vanadium redox flow batteries are the way to go. They say it lasts 25 years, but that's just being conservative, it can be recycled indefinately. Non-toxic, no chance of catching fire and easily extensible.
.. but very expensive. I don't see where Vanadium competes against BESS consisting of Na for short-term and Fe (like Form Energy) for longer (even weeks).
@jonb5493 expensive, yes. But it is getting cheaper all the time. And still nothing beats it in longetivity. Initial high price and lower maintenance and no replacement costs. After 5-7 years, it's the cheapest alternative with the added bonus of less fire risk.
Sodium modules replacing LFP modules for even more cost savings? Are the individual modules in the systems using a standard size module so it’s easy to swap the modules out as chemistries improve? 5 years is a LONG time in the battery chemistry market!

Cobalt doesn’t come from Africa in spite of the terrible working conditions. It is predominantly mined there BECAUSE of those conditions.
Many countries including Canada have access to as much cobalt but safety restrictions and much higher wages make African sources much more lucrative.
In fact, there is a mining town in Canada named Cobalt after this and other rare earths that used to be mined there.

of course, we will reach that point. so long as government don't ruin the economy by trying to force energy system down a path before the technology is ready for it to be viable. They've already shown they are willing to do it with all the electric car mandates that are never going to be met.
@@ge2719 The government is a completely corrupt inefficient system.
This is part of it, but the only way to balance the energy needs and taking care of the environment is human-centered economic degrowth.

Point of clarification: Rolls-Royce Motor Cars Limited was created by BMW in 1998 and is completely unaffiliated with Rolls-Royce PLC, the owner of Rolls-Royce Power Systems and the MTU brand. Rolls-Royce hasn't made cars since its bankruptcy in 1971. BMW licences the brand and logo, but the cars share no lineage with the cars made prior to Rolls-Royce's bankruptcy.
The car lineage is via Bentley. The Crewe factory has been making cars since 1946 and continues to do so, even though it is now owned by VW.
en.wikipedia.org/wiki/Bentley_Crewe
Even companies with traceable lineages have evolved to treat the automobiles they produce as a side effect to generating revenue from subscription services. We have BMW attempting to coerce customers to pay for heated seats, or GMC pushing Onstar, or Mercedes-Benz hawking driver assistance, all the while selling driver data.
@@catsupchutneyWe’re getting side tracked, but:
1. Capitalist companies didn’t suddenly start following capitalist ideas. They’ve always been money first, because without money they fail.
2. BMW trialed heated seats as a subscription in exactly one country based on user feedback. The trial didn’t pan out, and they canceled all roll outs.
3. Economics of scale have meant that features are often technically included in a car, and not turned on. You (or the original owner) may not have optioned heated seats, but the seat may have the coils. Find a button and attach it to the wires, and voila! Heated seats!
People are complaining that battery cell tech never makes it to market.
It can take years to get from the lab to commercial penetration. 1996: John Goodenough and his team at the University of Texas at Austin discovered the LFP cathode material. Pattent was granted in 1999.
The global LFP share increased to 34% in 2022.
November 2023, LFP batteries captured 31% of the passenger EV battery market.
The forecast is to reach 39% by 2024.
In China, LFP batteries now make up over 50% of the EV battery market in GWh term.
Interest in battery cells has increased somewhat and perhaps that will accelerate the required time.
You left out that the LFP patents expired at the end of 2019. That's a big reason for the post-2020 surge in LFP batteries in the US.
I wonder if LMFP can take it to next level as that will have density between LFP and NMC batteries.
I celebrate every new (potential) track that opens in the sustainable energy space. More innovation; more progress

I will watch what CATL warranty is for those batteries, without such low degradation no one should be able to beat there's warranty.

@@veganpotterthevegan Every company in the EU has to keep spare parts for at least 7 years after the last sale, so anything less than that is lack of confidence in the product.

@@UndecidedMFBattery industry plant confirmed. 🥸
5 years without degradation sounds like they under-rate the batteries and hide the degradation for 5 years
You beat me to this comment. I was thinking the same and wouldn't put it past companies to do this. I don't think Matt mentioned what the degradation would normally be in 5 years. If it's only like 5-10%, you just make the batteries a little bigger and hide their extra capacity as headroom to make up for the degradation.
They are probably achieving having no capacity degradation in the first 5 years by cheating a little. And the 15000 cycles quoted hints at exactly that. The capacity degradation of LFPs over 5000 full cycles should be about 20%. However, if you make the capacity 20% larger to start with but never allow each cell to charge to more than about 85% then you should only see about 5% capacity degradation over 5000 cycles. So after 15000 cycles, or 5 years, you should effectively see no actual degradation on the quoted capacity.
It should be noted that LFP cells already easily outlast any power electronics associated with them and have for a long time. So, this is good progress, but it isn't earth-shattering. Also, as with most ESS manufacturers, CATL likely builds some buffer room in their capacity guarantees verses the actual capacity of their cells. Their ESS systems (and certainly their marketing) are likely programmed only to the capacity guarantee. The cells probably do degrade (but LFP degrades very slowly anyway)... but its hidden for a time by the buffer.
In anycase, this is almost a moot point. LFP cells have such low degradation that the actual cycling is almost irrelevant... Calendar aging does more damage. And as I've mentioned several times, the power electronics associated with these packs will fail long, long before the cells do. Even with regular LFP cells. As a maintenance item, the power electronics represent a much bigger fish.

It's interesting how fast things move. While solid state seems like the ultimate way to achieve potential airplanes, etc on electric, I feel like sodium ion is going to be the biggest growth area soon. Natron Energy is building a 2nd plant in the USA and while it may not work well for cars yet, the storage capacity and price seems like a win win for everyone. Though I have a few LFP cells for a home DIY battery, I am now hoping the salt battery cells start showing up to build longer lasting storage. That Natron's cells supposedly do 50,000 cycles and full charge in 12 minutes is damn impressive. Thats a lifetime battery right now for most who could buy one (though I dont think they are for homes yet). I could see however if they can increase the capacity without weight in the next couple years, we could see affordable 25K EVs with 500+ mile ranges.. maybe not 0 to 60 in 4 seconds or so.. but I would argue most people would want a 500 to 1000 mile range on a 12 min charge over a couple seconds faster to 60mph. Especially if it could also last 20,000 to 50,000 cycles making it a 100 year+ battery.
IF EVs are going to be able to get 500+ miles, in any weather, without degrading, in about 2 minutes.... I'll just wait a couple more years for that then and keep my gas car meanwhile which already does all this.
Reminds me of the mid-70s and the oil crisis when Popular Science had several articles about the latest in batteries for the upcoming surge in EVs. For cars, rapid recharge was right up there with energy density. The two “front-runners” I remember were one using molten sulphur as the electrolyte - a bit of a concern in an accident - and an “air-aluminum” based setup. This latter one “consumed” aluminum sheets so recharge just required replacing the sheets and removing the oxide for electrolysis back to aluminum but was extremely sensitive to CO2 in the air which was already too high back then

For static electric storage with a long life, a flow cell can not be beat. It makes Lithium batteries seem like they maladapted for this utility.
All these pieces of knowledge help guide the future successes. Oh, those marketing guys! Hydrogen and oxygen "self assemble" into H2O.
Somewhat, in the case of a fuel-cell such water self assembly needs a little helping hand from a platinum catalyst to break gasseous dihydrogen into hydrogen to help create water by reaction with oxygen.
That’s to distinguish between a catalytic reaction and a normal one.
Absolutely fascinating video! The TENER battery's potential to maintain performance for five years without degradation could be a game-changer for the EV industry. As we push for more sustainable energy solutions, innovations like this are crucial for enhancing the efficiency of electric vehicles and renewable energy systems. I'm excited to see how this technology evolves and its impact on the future of energy storage. Thanks for sharing this insightful update!
15k cycles/(365 cycles/day)=41 years, no degradation in the first 5 years means nothing.
Also, there's no such thing as zero degradation. You just provide more over provisioning and by the time it degrades to its nominal value, the outside world sees zero degradation.
Also, 15k cycles is not absurd even using existing technology. A 2k cycle rated cell (at 100% cycle depth to 80% capacity) can cycle 15k easily at 70% cycle depth at 50% remaining capacity and 2x the internal resistance (still quite useful for grid level storage).
CATL did make technical breakthroughs, but the marketing material is certainly over-hyping them.
@@bskull3232Yeah, I don't see the hype for "zero" degradation. It could be nice, but not the deciding factor. LFPs can already last more than a decade with minimal degradation and it's not like they stop working past the rated cycles. Just like with solar panels.
Price reductions are far more impactful. You could probably buy better batteries at less than half the price before the end of its rated cycles.
@bskull3232 - 15k cycles /(365 cycles/day) = 41 days. Did you mean 1 cycle/day?

Thanks for an excellent battery chat. I have been planning on using the huge base structure of my machine to house large battery storage.
My principle in life is to live as you go with what technology is offering at that point in time. We currently have 2 fully battery EVs and enjoying them. If we live long enough and something else comes up, we go with the flow.
It just seems like battery tech is changing daily and I can't even catch up what's out there anymore. As long as they are cheap and last 20 years, I'm good. Everything else is a bonus.
For home storage, V2G is what I think will win. If Solar and ESS are distributed from homes, how much commercial storage will we need?
I think the biggest advancement would be an aftermarket solution to use a Tesla car. They are dirt cheap used for huge capacity. Just need the interface with your home electric grid.

I might not have an engineering degree, but I see a solution to this where you don't.
I'm pretty sure you are assuming that someone won't disassemble the battery.
If it's a Tesla car that's no longer useful (or more likely, that is getting you laughed at in public due to it's link with Elon), then you have a lot of components that make up a car, but can make up something else with some effort.
Take apart the battery. The battery is made of a great many individual cells, and the idea with disassembling the battery is to liberate the cells and reassemble them into some number of series strings of cells that total up to no greater than 48v at full charge for any single series string.
Commercial off-the-shelf pure-sine-wave inverters are able to accept that 48V input voltage and output more than enough 120/240v electrical power to support a typical American home.
The only sticking point, and the part where your MSEE would come in handy, is that to ensure the safety of and prevent damage to the battery bank, a BMS and charging solution different from the one in the "standard" Tesla would be needed, due to the different electrical configuration of the battery cells.
Since I have no such electrical engineering degree, I'd be looking for something that meets my needs that is available off-the-shelf, but a bespoke solution would be more easily tailored to fit the specific needs of the rearranged Tesla battery pack.
What does all this accomplish? Well, at the very least, as far as the IEEE is concerned a battery pack that is 48v max is still "low voltage".
So technically the only time I would be required to "mess with high voltage" would be when I disconnected and took apart the battery pack.
I would of course be wearing proper PPE while I do that, I want to keep my eyes safe from the light produced by an electric arc (by not making one and by having PPE to protect my eyes if one DOES happen), and I want to stay alive (by wearing the properly rated rubber electrical gloves, I can pay for the right ones if it means I get to live despite maybe making a mistake, as humans do).

The issue with LFP’s is they are still dependent on Li.
I'm undecided... Do you have enough data to support that batteries are eco-friendly when compared to conventional ways of energy? Sounds like a dumb question, but extracting lithium seems like a dangerously pollution process. Could it be a good title to compare the different energy technologies in terms of pollution thru their lifetime?
every manufactures do damage on environemtn. EV and ICE both damage on nature when thsoe are manufactured. But during operation, EV do not produce any pollutions while ICE do produce so many pollutions from engines. Electricity from EV comes from powerplant that are being used in the past. We don't need to build new powerplant for EV. So in other word, EV uses electirc pwoer grid that existed in the past while ICE must pump out oil additionaly in order to operate. So ICE use extra energies that we don't have to when we use EV. So EV saves overal energy usages. At the end of lifespan of both EV and ICE, ICE are piled up on garbage field. While EV's batteries are extracted and re-use on ESS system for decades. So EV is much more environmentally friendly. This video says CATL makes special cells for ESS blah blah blah. Don't listen to it. Future ESS market will rely on re-using cells that are extracted from EVs. This is part of battery cell life cyle in future battery industry.

I'd like to get your take on the recent development with zinc-halide battery chemistry. My understanding is that similar to LFPs they're not as energy dense, but safer still and zinc is significantly more available than lithium. Everything I've seen indicated the intention to use them specifically for ESSs and grid support but I'm personally hoping to see home battery backups and UPS systems using it
Thanks Matt! Steps towards ending dendrite degradation is exciting
LFP cells degradation is already so low for many use cases that the reduced degradation claimed (to be confirmed by how much) for CATL's product might not make that much of a difference in practice.
The first thing that came to mind was that they'd guarantee a lack of degradation for 5 years is a capacity buffer. And it's probably what it will be anyway if they really want to guarantee NO degradation.
In a few years it's gonna seem crazy that we ever used something so flammable as lithium for this. You should do a video on Eos and their Z3 cubes. Non-flammable American-made zinc batteries.
The fact we still need more batteries just proves my point, that while power generation still need to increase, it doesnt have to increase what coal and other power sectors were trying to say that we needed to hit. The fact is we WASTE a ton of power everyday to nothing. Now that we have some way to store it we are seeing the need for power generation is actually dropping thus we're hitting to a point where renewables are even able to keep up with the base load power now just from a few hours of the day in the sun. Also while I loves to see more LFP - NA still to me seems like the clear winner when it comes to grid and home base power needs. If LFP is already doing this much work, cant wait to see what hybrid NALFP brings or even just raw NA (both sides of the battery) can bring next in terms of cost.
This is the thing. If we create a smart electric grid, everyone's electric car could be that dynamic storage. Charge them when there is excess, use the car batteries power for high demands. With it being smart, you can program your car to give or take as much as you need.
The biggest problem with Lithium-Iron-Phosphate batteries I've found is they REALLY don't like cold temperatures...every LIP battery I've looked at recently holds much more power than a standard Lead Acid battery of equal physical size, but all of them list the cut-off Temperature below which they will no longer accept a Charge is 4 C (39.2 F)...considering I live in Southern Ontario and it tends to be at or below 4 C from Late Sept. to Mid April, it means they're worthless to me...
You can get batteries that have built in heaters for low temperatures, though the battery heater will use some of the battery power.
@@rossallen738 True but the space in the case the heaters take reduces capacity and then the heaters themselves reduce apparent capacity to the point that they are effectively lead acid batteries in terms of actual sub-zero capacity, not worth it for powering my Mobility Scooter in the winter...
Great video! I never get tired of battery videos. I don't use enough electricity to get solar plus the grid here is from hydro power so my distant "Backwoods" dreams of an off grid system seem silly now.😊
Given that ESSs are principally there to get more use out of renewables, how many charge/discharge cycles per day are they expected to provide? I would have thought one or two would be all that is required, solar charges the ESS during the day and discharges at night. On that basis 15,000 cycles would last for 41 years without degradation! 5 years without degradation suggests 8 cycles or more per day. Thanks Matt for another brilliant video.
5 years and 15000 cycles are separate claims. 5 years, no degradation (1 cycle per day = approx 1500 cycles) and 15000 cycles total expected life.
A few percentage points in degradation in years 0-5 can be easily compensated for by just making the battery a bit larger and heavier. For instance, if existing tech would result in 6% degradation after 5 years, just make the battery 6% larger to compensate, problem solved.
What would make me more impressed about the technology is if it increases the total lifespan of the battery, allowing it to continue to be usable beyond 10 years or 20 years. That would be real progress.
LFP can already be cycled at 80% DoD once per day and still have 80% usable capacity after ~15 years. Which is still plenty useful. Calendar aging where it starts to really drop off its capacity is said to be at the 20-25 year mark. But there's not a lot of solid data there.
But what is its drop off curve after 5 years? The same as current ones, or does it take a dive.
I just read that iron-air battery (reversible rust Battery) are being used as storage by Form Energy in Minnesota. It is said that solar connected to these batteries can be run a few days, making solar power always available. These iron-air batteries aren't nearly as efficient as LFP batteries; and I think they are currently more expensive. They are also bulkier that LFP batteries, so not optimal for automotive use. But what a concept!
They are a form of redox battery. There are some vanadium and I think magnesium ones that were interesting to look into.
What would be a real game changer would be a small, cheap, modular plug&play home battery that you can install easily with a small capacity to begin with and then upgrade over time.
18.000 people working in the R&D department of CATL, including 250 PhDs... let's expect quite fast quite many innovations for higher efficiencies, longer lifetimes, less material use, and lower costs
And precise control how long each product lasts...
The cabinets are similar to what I had been helping manufacturer at Torus. They just opened a facility in salt lake to start their production line. Though they have been also making flywheels.
I have been on the fence adding energy storage to our Solar with the emerging battery tech. I think I'll be buying one of the new systems next year and hope it's everything we want it to be
Hopefully the Grid won't go down while you're still on the fence!

Bio-mimicry will be the future of our technological design! Hearing that we're starting to incorporate natural solutions to our energy problem is so exciting
@Matt at 4:40 you mention 15k cycles = 5 years. It is 8 cycles per day. I guess these energy storage sites have 1 cycle per day (charge at daylight, discharge in the evening till dawn). Wth 1 cycle per day 15k cycles means 40years. How is that?
Ugh ... sorry for the confusion. I shouldn't have said "over" in that sentence. It should have been 15,000 cycles OR five years without signs of degradation. Also, keep in mind that batteries in some of these systems will be cycling multiple times per day. Many utility scale battery installations are doing energy arbitrage and storing and selling off energy to maximize cost savings for the utility as rates and use fluctuates. It's not always about carrying through an entire night.
How much would a 1Mwh Tener BESS cost? (Not the whole container) Somehow it's difficult to find pricing details for this one.
My only question is, sure, it works flawlessly for the first 5 years.... after that does it fall completely apart? Does it degrade at the normal rate after that? What's the tradeoff?
"china claims"
@@fredlacroix6865 it's not like there aren't highly questionable "US claims"
I am guessing no. its just 5 years before there is any degradation. Even if it's the "normal rates," you are going to get another 5 years before there is any noticeable reduction in storage. If you plan on a 10% overhead, you can get 20 years before you start needed to replace, or add more cells to the system.
@spencer9392 if it's actually 5yrs with no degradation after so many cycles, it may have 10% degradation after 20yrs for all we know. But until these cells actually age under heavy use, we won't know. Lab tests for 5yrs of use over 1yr isn't gonna be the same thing as thousands of people using these batteries for 5yrs.
Just bookmark this comment and come back in 10 years. We will have all of your answers.
This is why I think both CATL and BYD will be opening factories in the USA to supply EV battery packs and battery packs for power storage.
Don't forget their cheap EV's!
15 kw's does NOT cover the avg us household for 2 days. with wood heat in the winter we still use 30 kw's a day. the summer is more like 50-60kw's a day. you released this an hour ago.
kwh?
He might have got it the wrong way around, apparently the avg is 30kWh per day.
That said, except for the depths of winter I can cover almost our entire energy budget for most of the year with our solar output, I figure about a 10-15kWh battery would let us almost completely go grid power free. We don't have gas or other, I'd probably want some more panels if I had an electric car.
Sounds like you're well above the average. Average home electricity usage is 30 kWh/day. But agreed that 10-15 kWh of battery wont cover a house for 2 days unless the homeowner is very frugal with their energy usage.
He lives in the UK where it nether gets really hot or really cold and the houses are smaller. That is why they get by on 15 kwh.
@@suklee1400 kilowatt hours. It is a measure of the quantity of electricity. A kilowatt is a thousand watts. It costs from 8 cents to about 50 cents (USD) for a kilowatt hour if you are paying a utility.
5 years of no deg is impressive, but what is the practical lifespan of Tener ESS say to 15% degradation or 85% capacity left? And also is there a second hand market for "previously loved" ESS's?
Current VRLA lifespan is 5 years, have very little degradation over that period, and are completely recyclable and easily obtained and serviced.
Unless this 5 year no degradation claim turns into a performance warranty, its only music..
is it not possible to build HUGE cappacitors ... maybe cheaper and easier, becouse they need to charge at daylight and give away heir power while it's dark..
would be a perfect job for fast cappacitors instead battery's that degrade by time
Tesla Powerwall 3 uses LFP
Finally. I'm glad they moved to LFP for version 3.
@@UndecidedMF What happened to LTO? Insane longevity and temperature tolerance makes them the ideal choice for large scale stationary storage for me.
6.25 MWh is not an energy density, but an energy. An energy density could by energy per mass or energy per volume. What are the proper units that you meant to use? Thanks.
At night when the electrical power grid demand is low these Tesla battery packs are recharged. The benefit is your local power provider will need fewer power plants built to carry the heavy peak loads during the high power demand during the day. Resulting in a more efficient use of your power plants.
I have been looking into the new Tesla Aluminum Ion battery. This is supposed to last about 200 years with (if I remember correctly) and 50,000 cycles. It might be a good idea to at least look into this technology. If it is all true then an electric could go around 2000 miles between charges and is about 1/4 the cost of Lithium Ion batteries. Plus It is very safe and not subject to thermal run-away. Oh and last but least it can charge in only 10 minutes!
Oh..
Hopefully it doesn’t get in the way and degrade faster after the 5 years. Did they give degradation numbers for the longer term?
It says no degredation for the first 5 years.
Which begs the question...why 5 years? What happens after 5 years? Is it better than the edison battery as far as longevity goes?
Presumably they only tested to a certain number of cycles before they stopped their testing. Then the cycle counts were used to establish a time period for decay. Anyways at some point they just shut down the test apparatus.
Maybe they build in a buffer of 10% and that has worn away after 5 years?
I've been using LFP for power storage since 2019, what's taking so long?
Significantly safer than NMC and definitely longer cycle life.
Personally I wish they would invest more in the gravity hydro power plants then batteries.. but I am glad battery tech is moving ahead too
replying to your reply LOL - I am already subscribed, and comment a lot to improve YT rating for you. Now, expanding this topic, Forward Energy (you covered 2 years ago) are NOW installing iron/air battery in Grid , planned to run in 2028. Very exciting as iron/air potential is cost is 1/10 Lith. & and has very long discharge times (like days or weeks). Perfect Grid battery. Anyway Matt, maybe wait till 2028 see how they come up, although I see this as the missing ingredient in cost effective renewable grid proliferation.
Thank you Matt but the real questions to ask are : after the 5 years what is the balance of degradation for the following 5 years, expecting a life span of ??? It all boils down to the ROI. Lifespan is critical, recyclable etc many questions left unanswered.
Good points. On the recycling front these absolutely should be recyclable. There's a lot of really interesting movement in the battery recycling business too (LiCycle, Redwood Materials, Recyclico, etc.).
In any and every discussion of energy storage technology, the ability to FULLY RECYCLE the components needs to be mentioned. Whatever the degredation curve looks like, at end-of-life all the materials can be recycled into new batteries. This is why even gram of lithium needs to be captured from landfil NOW, like they're doing in Finland.
The battery likely has a 5 to 10 percent over capacity (reserve) that accounts for initial degradation. Many lfp cells niw have more capacity than advertised
Would it help with cooling / cogeneration to cover battery installations with solar panels?
I my not be the first with this but - isn't the simple way to give customers no degradation this: Oversize the battery pack and allow a large buffer when new, and gradually reduce the buffer electronically as the cells degrade like every other cell does? At first you give the user 85% of the true total capacity, and after 5 years you give them 95% of the lower (by then) true capacity.
I would like to see a price comparison for power and solar cost for a development like Homeowners Associations in Florida vs the same Kilwatt output and storage capacity. The cost, management, permitting and compliance are some benefits
I don't now if the Chinese claims are reliable.
You may want to run your own battery of tests.
China beats US in battery again? No way, impossible!!! And China beats US of A in solar, winds and nuclear energy?? Chinese are absolutely lying!!! And Chinese never killed any astronauts and built its own space station?? This MUST be CGI!
Just ask S. Korea...they just had multiple EV battery fires incidents from both a battery manufacturing plant (Chinese owned) and vehicles using batteries sourced from China.

The TENER battery's five-year no-degradation promise is fascinating! It's great to see such innovations tackling long-standing issues in battery tech. What other applications do you foresee for this technology?
Most forms of stationary storage need to last 15-25 years to make economic sense. If the short-term pause on degradation has any detrimental effect on long-term reliability, it may be moot.
Or be really cheap and have swappable components (although for the sake of the environment I prefer the first option)
@@drillerdev4624 Modular battery systems for maintainability will definitely become a necessity: I cannot imagine throwing away literal tons of batteries due to single failed cells in the whole unit being sustainable.
We're still ~10 years away from seeing how well the first wave of mainstream EVs and their batteries will age into retirement. I'm apprehending a nightmare of EVs getting scrapped prematurely due to single-cell failures and the inability to service battery packs in a safe, reliable and cost-effective manner.
I was just doing some rough napkin math for a relative's house that wants to cut their power bill. A $12k DIY system has a payback of roughly 8 years just switching from a flat-rate plan to time-of-use + battery storage. Well within the longevity of an LFP system. Looking at ~15 years before they degrade down to 80% with current tech.
On cnevpost they say "Tener has a cycle life of more than 15,000, which is 1.7 times the current mainstream level, and will not decay in the first five years of its 20-year life expectancy, CATL said."
Hey Matt, I’m looking at going solar and was wondering which solar panel you would recommend and what battery would you recommend? Please provide pricing as well. Thank you
Is there any ESS that's using hydrogen for grid storage? It recently occurred to me that using renewables to create hydrogen via electrolysis could be a seriously effective way of storing energy, since I know that's one of the biggest hurdles there are.
No, theres some research, trial projects and industrial usage but no active scaled deployment of hydrogen storage compared to battery storage. The economics is against hydrogen in this case as batteries are cheaper (capital and operational costs), more effecient, take up less space and require less maintainence. Hydrogen is considered where there is a secondary use for the waste heat produced in the hydrogen generation, processing and conversion to electricty steps, such as industrial processes.
Every channel says game changing every day. Start to feel the hype.
If a chemical change (like melting ice) stores power, then that chemical change in reverse (like freezing ice) releases power, and even if there are thermal losses of energy in that process, theoretically that process can be repeated infinitely as long as we have energy to input into the system. So theoretically, infinite cycle life is quite possible.
"power"
Melting ice is a phase change, not chemical change, but I see what you're getting at. Ice storage is already being used all over for commercial buildings. Charge up the ice tank at night when power rates are cheap and use the ice for cooling during the day. There may be some material that you can capture electricity with using phase change, but I don't know if any viable solutions exist yet.
@@andrewt9204 ice/water was a poor example and distracts from my main point of theoretical infinite cycle life.
Thanks Matt. 👍🏼
Love your videos, but struggling with conceptualizing what energy/power capabilities a mega watt or even kilowatt have. I’d love to see more analogies when talking about batter capacity. For example, “this is a 15kW battery, which could power --- for -- amount of time.”
You may have already answered this question in a previous video, but I'm curious, can the component elements of these ESS systems be recycled and reused to manufacture new replacement systems.
Thanks in advance...
Always Sunny reference! Nice! And obviously another great video.
The long-term problem with LFPs for grid energy storage is that they are the most sensitive to the price of lithium per kilowatt hour. This means that their success will ultimately lead to their failure as they consume larger amounts of lithium per kilowatt hour in production if demand for them skyrockets globally, the price of lithium will also sky rocket making them a less and less economic investment as they succeed.
In theory as prices increase new lithium sources would be exploited bringing the price back down. Although in the consumer world prices never go down that isn't the case for commodities. This can be seen at your local scrap yard. The value of lithium today is already spurring the development of new lithium mines. Like the one in Nevada iirc.
i am excited for all the new tricks for batteries and such.. I just hope they are not cheating. what i mean by cheating is making a battery 20% larger than they list and making it software limited so it only charges to the limit so as it degrades it still had rated capacity even if it decades.
5 years is a pretty good lifespan for zero degradation. Assuming they can still be used beyond that with some degradation being considered 'acceptable' up to a point; they should be really useful in getting some more stubborn folk on board. Still gonna have to do better though for the most stubborn folk.
And I must admit, I kind of am one of them in my own way. I want to see mass scale rollout of lithium titanium batteries, based on what I have been learning about them. If they are actually as great as claimed and somewhat proven to this point as I understand; then there will be very little reason to not use them.
If the Iron Phosphate versions help us get there, cool.
I wish more people did these kinds of videos in Hindi, I can share so much information with my parents who don’t understand English at all
Vanadium redox flow batteries are the way to go. They say it lasts 25 years, but that's just being conservative, it can be recycled indefinately. Non-toxic, no chance of catching fire and easily extensible.
.. but very expensive. I don't see where Vanadium competes against BESS consisting of Na for short-term and Fe (like Form Energy) for longer (even weeks).
@jonb5493 expensive, yes. But it is getting cheaper all the time. And still nothing beats it in longetivity. Initial high price and lower maintenance and no replacement costs. After 5-7 years, it's the cheapest alternative with the added bonus of less fire risk.
Sodium modules replacing LFP modules for even more cost savings?
Are the individual modules in the systems using a standard size module so it’s easy to swap the modules out as chemistries improve? 5 years is a LONG time in the battery chemistry market!
