I really hope high density, high power, low cost, long life, fire-resistant battery technology becomes a production reality soon. He seems to be projecting a few of those with his tech, but he is vague.
They have more information on their website and there are a few other videos out there about the process. At the same time they don't go into too much detail with the chemistries and development processes because of proprietary information and all.
The higher the energy density, the less stuff is left to get in the way of things going horribly wrong. The ideal battery (density-wise) would fundamentally consist of fuel and oxidizer with atomically thin separators and electrodes in-between. Should the slightest thing go wrong with the separator, such a battery would likely detonate. Safety requirements are practically guaranteed to set a much lower ceiling than then fundamental chemistry is theoretically capable of.
Greed slowing down progress , for really good safe high capacity ( 500Wh/kg ) and cheap batteries ( 100kWh EV battery pack under 10k $ ) we will wait at least 10 Years .
@@lesnypatrol7292 that is all speculation. GMG did say they were finishing a graphene production factory, which suggest they are ramping up production. Things like that takes time and investment. I think it more a case of finding a cheap manufacturing process and battery chemistry that uses cheap materials. So many variable to making a battery that works. People create these things for money, the faster they make them the more money they make, if anything greed will speed this up. The demand for high capacity batteries is so great that you wouldn't even need to manufacturer your design if you owned a patent. Even if you charged tiny $1 for every kWh made based on your patent and they were put in 100 million cars with 100 kWh batteries that would be $10 billion dollars. Then there is everything else, house, planes, trucks,tools, phones, computers etc.
Excellent interview. Your skill in selecting topics to discuss gets better all the time. Interesting tech. It obviously is only in the development stages. Sounds like even if they get the tech dialed in, they have no idea what it would take to scale it up. As with many new battery technologies, scaling is massively important. I also wish he would have talked more about cycle numbers. Energy density is important but cycle length has been a limiter also. They are not even at a point where they know what the end battery design would be. Thanks for shedding light on this technology. Best interview on your part I've seen.
Love the coverage as a long term stockholder of theirs. Im also getting excited about GMG's Thermal XR which should be approved by the EPA this year and has been been validated by the University of Queensland. Hope you will cover ESS inc. next!
Check out James Tour. Inventor scientist. New graphen manufacturing method that also produces hydrogen. Don't believe in hydrogen cars, but I think it will have uses.
Thanks guys. Excellent interview. I really hope that these cells make it to market in a big way. The raw materials are abundant, and the technology seems to be safe, giving cells which could handle wider temperature variations than Lithium-based cells. This will eventually lead to lower cost per kWh. Please keep us updated about the progress of GMG's development programme. 🙂
Very interesting approach and it seems like the potential is a significant step up in energy density, therefore more applications where more power is neeeded. Worth following but it seems like patience and persistence are warranted
It all comes down to commercial viability and scalability. Doesn’t matter how good a technology is if you can’t manufacture it at scale in an affordable process. That being said, with as much money and effort being put toward battery tech we will crack this nut.
Why don't these high tech battery companies go after the lead acid car starter battery market? Lead acid batteries use 2 volt cells. The car lead acid batteries are specifically designed to discharge fast and recharge off the alternator. It is something that these batteries could easily do, plus with the high amp hours you won't have the problem of your lead acid battery going dead if you left the lights on, (as long as they are LEDs). If these batteries are able to charge like lead acid batteries and they can match the cost, they have a huge market to sell into. Just think about all the cars, trucks, ATVs, motorcycles, boats, etc. etc. etc. that would have owners and manufacturers willing to swap them out, even if it is just to replace a lead acid battery that is going dead.
@@shmayazuggot8558 Yeah. Why? I have heard that Lead-acid batteries perform well in gasoline-powered vehicles because they produce the high output needed to start the engine. I guess that's why even Tesla until just last year used them in their very sophisticated EVs. But I found a company that claims that they have a drop in LifePo4 replacement for Tesla's lead acid battery. I haven't read any reviews. The Tesla continues with the your 12v battery needs servicing message. The company says to ignore it and use their BlueTooth enabled app to see how the health of the battery is. It seems that batteries have to be designed to be 12v for their particular car and can not just be replaced by a lithium battery. I guess 2022 and newer Teslas were designed around their new 12v lithium battery.
Whoever gets to 1kw per kg in an affordable battery that's tougher and longer lasting than LFP that can sustain a CONTSTANT 350KW or higher charge rate just basically buried the ICE. That'd be 0%-100% in 17 minutes in a 100kwh battery.
Excellent coverage. Thamk you. New stock holder here. Growing my position as GMG proves successful going to market. As you must all know, Graphene is notoriously difficult to work with, so, expecting things ro take longer than expected. Been using a graphene additive in my oil and there is a clear difference. 5-10% improvee fuel economy and less noise from my engine. A Prius with nearly 300,000 miles on it. GLTA
I'm taking a 18650 of 4Ah, and get 306Wh/kg. If I _need_ 300Wh/kg, I'll use 4Ah battery. Not 3200, nor 2500, nor 1800... Li-ion can do in 300Wh/kg with only one electron. To see how three electrons work, we need 1kWh/kg from GMG PS from wiki: When this is taken into account, theoretical gravimetric capacity becomes 67 mAh/g, That means 3300mAh per 18650 (about). This is why GMG used so many years to solve that problem somehow.
Let's hope they are successful, but he gives the impression of being undercapitalised to bring the product to market fast enough to not be left behind by other battery tech
At 15:55 it's just the series and parallel math. Watts is v*a so Wh also is your final density figure. For any given application you just use whatever quantity of cells gets you to the needed voltage. If it's twice as many because the vpc (volts per cell) is less, then you just use twice as many. Again, back to watts and Wh, it doesn't matter which voltage you picked or number of cells in series. This is all just basic battery pack geometry stuff that already depends on the chemistry, which each have their own vpc.
Interesting though unfortunately a long distance to scale up. Sodium batteries are probably the next wave as scaling is easier. Good to see competition in the energy market.
AlCl3 Aluminum Trichloride has a health hazard of 3, listed as a hazardous chemical. I bring this up just as a data point, as it would likely require special handling on the production side, and possible later in use/recycling. Think of all the chemicals/materials used in the past which have become pariahs, e.g. asbestos, or firefighting foam. So to me this would be a concern. Thanks for the informative interview. I'd love to see 1kW/kg, for selfish reasons, more mileage in our EV car and a useable EV motorcycle. Likely work great for aviation applications as well.
At least from what I can see from the interview , is a difference between he and his company and Elon and his company is urgency. They're building a little bit at a time when
As a shareholder I'm very concerned...Craig just described this battery as an Aluminum ion battery with a graphene component, where as this company has been advertising a graphene battery with an aluminum component. I don't believe this is the best use for the wonder material that is graphene, but instead just the simplest way to get a battery working while using a graphene component. I hope someone can challenge my assumptions.
Aluminium ions are the active species, the same as Lithium ions in LIBs. The graphene would be used on the electrodes to allow for intercalation of the Al ions (storing of ions on the negative electrode), similar to graphite electrodes in LIBs. So technically, yes it is more informative to describe the GMG battery as an "Aluminium Ion Battery with a graphene component" since aluminium is the active material in battery lingo. The prior marketing of a graphene battery with aluminium was most likely trying to highlight the unique technology GMG has with graphene integration (different from graphite used for lithium batteries and other Aluminium battery attempts). Hope that helps with your worries!
There's simply no such thing as a "graphene battery". You can use graphene in lithium-ion or aluminium-ion or probably even sodium batteries and it should improve performance over graphite and other materials used previously, but metal ions are still moving the charge around. The "graphene" emphasis is just marketing strategy more than anything else.
The big reason a battery catches fire is the presence of oxides, because it acts as the oxidizer black powder, without it it relies on air to burn, making it much harder and less intense as well. That's why lfp has lower fire than nmc chemistry.
Really hard to hear this guy. He may have a great idea but he should not be the company spokesman. Hope he either gets enthusiastic or hires one who is.
Saw the presentation one and a half years ago and taking a long time to get to commercialisation, the key point here is cost per kilowatt ...... had enough time to develop one kilowatt battery,
They had to develop the graphene manufacturing first, like how @AORD72 talked about "bottleneck is graphene production. Hence currently making coin cells". Be interesting to see what happens next year if they ramp up graphene production.
This company has the right idea and is one of the most sustainable ways to develop the graphene for these batteries especially if they use RNG. Definitely will be a massive game changer once they scale up! It would be great for them to partner with a company like Hyliion with their long haul trucking RNG PHEV solutions. I think the two companies have a lot in common in terms of their ultimate goals and how they can mutually help one another.
3.7 volts to 5 volts and 500mA can be accomplished if the graphene is added with a certain additive but then heat can become an issue. But that can also be monitored and controlled with a design that I designed myself.
Robert Murray Smith has been working on this for years. This is open source material. Hybrid battery capacitors hope you don't claim you invented and patented it.
They are already making making coin cells. The bottleneck seems to be graphene production and they said the factory for mass production of graphene will be finished this year. Sounds far more advanced than just lab experiments..
@@AORD72 Hell, they are already making the pouch cells. Problem is getting the production of working cells up to a consistent rate. From what it sounds like they may have the majority of produced cells not working, so it would need a much higher working margin to be worthwhile? Needs more investigation on that front. Graphene, since it is a nanomaterial, tends to be hard to work with, on a consistent basis
@@teknosql4740 Around 500 USD per gram. Or ten times more expensive that gold. Of course, it could dramatically decrease with advancements in manufacturing process.
