Can Batteries Power Everything? This video is about the physical and chemical limitations to electrolytic batteries, and how we might surpass the energy density and specific energy of lithium-ion batteries (like the Panasonic 18650 batteries used in the Tesla Model S, for example).

You made lithium react with argon?!
LiAr!!!!!
WazzupKMS ha.. hold this L
uh man... I was gonna make a chemistry joke but all the good ones argon.😓
We can't find any good chemistry jokes because the chemist barium.
And that is also why you have to torture the rest of the world with the retardedly idiotic cancer that is the english language and its 95 % homophones and their users who think themselves oh so fucking clever when they come up with puns at this level of difficulty. Woohoo.

Did NOT expect Sam and Niko in a minutephysics video.
I used to work for Freddiew so I was in those offices a lot, and I'm from the same part of MN as Sam, Niko and Jake (raced against them in high school cross country skiing!). Wren has done some 3D vfx for MinutePhysics in the past - the video about how bikes stay up.
You should've included Peter "42" in your cloning videos :)
I knew there was a connection but i didn't know this!
Awesome!
Just crazy to see animations in places you would never expect.
Power the planet is kind of misleading, you don't necessarily want maximum lightness and energy density for powering the smart grid, you want ultra reliable and dirty dirt cheap.
Electric cars actually benefit far more from fast charging than from total range. If you only had a hundred miles of range but could charge in 5 minutes and charging stations were almost as ubiquitous as gas stations, you'd be all set.
Ryukachoo Well, I think a lot of people would still find it tedious to have to stop to charge that often
Make the charging and cars automatic. Just sleep the whole ride.
We need another battery tech leap that will make lithium batteries look like NiCD/NiMH.
Ryukachoo exactly, and for onsite power storage at solar or wind farms weight matters far less than a mobile device. I'm not sure where development is, but that where the molten Na batteries minutephysics alluded to are going to be used. There are prototypes about the size of a shipping container developed at mit I think currently in testing.
However, it does point out that an Electric plane is a tough feat to achieve without Some way to recharge while airborne, since high power/low weight is crucial there
Ok how about lithium-6 instead of the natural ~95% lithium-7 currently used, that should drop it by 15% for the lithium weight right? Also Lithium 6 is pretty easy to isolate.
But how cost effective would it be? Im sure that with government uses cost wouldnt be a problem, but how much would the cost go up if you were to use lithium-6 in a phone?
IN ENGLISH DAMMIT! (Joking, love you cody)
Make one (a Lithium-6 battery that is)? I'd watch that video.
Idiot
No, the calculation isn't correct, unless the battery contains ONLY lithium, you'll have to add sulfer/oxygen/whatever other elements into the play
When younger and we had power outage, I use to love it. Get the candles out and chill out. It was a nice change of pace. The most awkward time I ran out of power was while on the phone. My shaver running out of power is also annoying.
its an awesome day when minutephysics uploads!
same bro
Very true
Software Man ii
I used to use wireless mice for my laptop pretty much exclusively. Frequently, the battery would die at inconvenient times, and I had to start keeping a fresh pack around at all times. What's worse, is that it would never die fully, and then I'd throw those out. They'd die slowly, only failing for a little bit at a time, and then progressively more until I could get nothing more out of them. This helped them last longer, but it was also much less convenient. I also would often run into other problems with the cheap $15-20 mice I was buying, and would have to buy a new one.
Just this last year I invested in a nice wired mouse, and the inconvenience of a cord has been much more manageable than the inconveniences I'd had with wireless mice. I used them for several years, and it wasn't really worth the hassle.
Perfect world:
Fusion Power to generate electricity
Efficient Hydrogen storage for vehicles (make hydrogen by electrolysis)
Therefore, no batteries. They're quite heavy.
Hydrogen leaks a bit too much. Methane would be a better choice.
Better to supply electricity from underground superconductors or overhead catenaries than batteries or hydrogen for daily vehicle uses.
Jared Maddox Good point, well made. Maybe methanol would be even better - liquid storage rather than compressed gas, so safer, and easier to use in things like aircraft engines for long haul.
Hydrogen isn't efficient.
For passenger cars batteries are better:
- more efficient - about 80% vs 30% overall
- safer - increase body strength, decrease rollover risk
- easier to fit than hydrogen tanks - can be laid flat under the floor
- can quickly ramp up power output - useful in many situations
- can be charged at home for free
- cheaper - both batteries and electricity
Hydrogen is better for bigger vehicles:
- adding capacity doesn't increase weight as much as in batteries
- no need for instant power ramp-up
- more space for tanks
- quick refueling at hydrogen stations - perfect for long-haul semi trucks

Wendover also uploaded a video a few minutes ago sponsored by Anker, coincidence, I think not.
Nuthin141 I was searching for this
Nuthin141 Real Engineering also just uploaded at the same time too
WAKE UP SHEEPLE!
Nuthin141 Yeah I saw. Seems fishy...
Kevin Chen was about to say the same, literally just watched Wendover's vid before this
Good video guys! I think it's really awesome to learn about batteries.
Great video and congrats on the awesome sponsor!
MinutePhysics and Real Engineering? best day ever!
My first thought when you mentioned Li - Flourine batteries. "Hell no."
I don't think that even the _Nazis_ were insane enough to try Li-Fluorine, probably the only way to make it worse is to add Sulphur (for the smell), and upgrade the Fluorine to either FOOF or Chlorine-triflouride. There's just not much more "No" left on the dial at these heights...
@@absalomdraconis Yes great idea, let's also make the containers for all these dangerous substances out of nobelium. Now if the Li-O2F2-S-ClF3 battery doesn't work, you have a very powerful thermoelectric generator for a few hours, and the decay products can also generate a lot of radiation.
Good sponsor choice! Bought one of these 4 years ago and its still working as intended.
YAAAY a collaboration by two of my fav youtube teachers! On a subject that is vital to the immediate future of humanity.
Can we just appreciate his hard work for every video?
During all of this you assume that we'll keep using the same liquid electrolyte we're using now. There's good reason to think that this won't be the case in the future. Solid electrolyte batteries like Goodeneough/Braga's glass-electrolyte design could improve the energy density way past the figures presented in this video.
Agreed, and it's super interesting stuff! But I underdtand why he skipped it for this video- you have to draw the lind somewhere, and switching electrolyte doesn't explain the gains until you introduce voltage curves and get into some EChem.
Definitely worth an educational video if our favorite youtubers are willing to give it a go, but a bit too in-depth for here maybe.
I have an Outdoor Anker speaker and it is amazing it's been through mud, snow, and water.
Great video as always.
Hey, minutephysics, what about graphene?
It is a good conductor, but not a energy source
Well, obviously the graphene itself isn't an "energy source" - neither is lithium, nor even hydrogen (it takes more energy to manufacture a hydrogen cell than is delivered by it - it's not a fuel so much as power storage), but I've definitely heard of graphene being used to create batteries with more energy storage capacity than existing lithium-ion batteries, though I don't know the details.
Well yeah it sounds weird since having a good conductor shouln't make a huge difference because one would think that the energy source is what matters the most. I could be wrong though and it would mean that there would be huge energy loss by the resistance of the battery. That would mean that batteries would get really hot when in use but that is not what usually happens when I'm using them...
graphene and carbon nanotubes can't be the answer to ALL of our problems . . .
en.wikipedia.org/wiki/Potential_applications_of_graphene#Batteries
power the world? all the devices need to be light and trasportables? Always thought weight is not a problem for micro and macro grid.
Right... Weight is important for electronics and transportation, but nearly meaningless for general storage...
just got so excited hearing real engineering in the vid!
Great channel! Keep it up.
Knowing me, I'd still probably lose those batteries..
_Y O U A G A I N_
You really like to self advertise your channel huh? I've seen you on LOTS OF videos.
Paul last, if he is, he's doing it in a pretty clever way with all dem witty comments.
Brian Ngoma Eehh, kind of? Personally I think, not really, maybe that's just me, because I've seen quite a bit of these "comments" from self advertising channels, that honestly it gets on my nerves everytime I see one. I just see it as "What is something good that I can say to promote my own channel but not doing it in the form of 'check my channel' comment, hmm maybe this? Ehhh close enough, okay post!" comment.
What about Solid State Batteries? This could be a revolution!
BUZZ WORD. Yea the ones that media talked about to excite you. Yea those don't exist. It is in testing and no conclusive evidence it works. Not to mention that other better things have come up in the past, but never existed. This is because in testing they could explode or poison a person. Maybe there is a mechanic that we don't know yet stopping it. Currently Solid State batteries are just a hope.
As I said: This COULD be a revolution. I know that they are still under development.
there has been around 100 new battery technology announcements in the past few years
the funny thing is that they never make it past that
Muzikgod yea source me a picture of it then? If it exists then you can 100% prove it right? No you can't because the only thing we know of them is a paten by Toyota and a guy claiming he knows how to do it. He didn't even claim he has done it. There is no solid evidence that says we can even make a solid state battery.
Want to make this also clear. Big difference between a usable solid state battery and a non usable one. We can make one at extremely low temperatures, but not at a temperature of use. Which is what we are talking about.
Muzikgod nope
great great video and explanation
I love the way you explain
Or if you want to make it lighter, put helium in it... duh.
OceanOinker That doesn't make it lighter. It just changes the average density. The total weight still increases.
Oh, okay. I just thought that cuz helium balloons rise
Actually it would make it lighter. It would also make it more massive. Mass and weight are different. Guarantee you will loose weight if you tie helium balloons to you.
nope, helium does *NOT* have a negative weight, it just rises because it is lighter than air
exactly, so on a scale, if you tie helium balloons to a battery ( or any object ), then it would weigh less on the scale, making it lighter, right?
0:10 was that niko from node
Rapth in an above comment he mentions that he grew up with Sam Niko and Jake and that Wren has worked on some 3D aspects of his videos before!
Who are these people, Niko, Sam, Jake, and Wren I've been reading about in the comments?
pennymac16 they are the team behind Corridor Digital, who make short UA-cam vids, alongside feature length movies and shows, commercials, and also a blog called Sam and Niko (which is why we know about each person). A clip from their blog was used in this video (the GoPro on an arrow).
@Peregrine I see. Thank you so much for talking the time to write such an informative reply =)
Am I the only one who sees the humour in the illustrations ? Raelly excellent for forming visuals on complicated concepts and remember easily
Great collab project!
We'll figure out fusion. In 20 years... and 20 more years... and 20 more...
Then we need to figure out how to do something other than heat water with it. Which will take 20 more years...
We already know how to do more than heat water with fusion, heating the water is the bit we _haven't_ figured out.
Do you think the first person to arrive in North America said; "First"?
You'd have to go back many thousands of years to find out.
First in Native American.
Once they had a language with the a word for "first", someone likely said it.
Anker is great. All other powerbanks I used so far died really quickly, my Anker ones are still going strong. Got a 20k mha Power Core II and I love it!
Very Educational
who else used to think Li-ion was Lion battery when he was young?
is it true that the making of a tesla car have a carbon foot print of a regular car used for 8 years ?
Bob Robert yeah, but I don't think saving the environment is the end goal for Tesla cars.
The idea is to switch to a more sustainable fuel source and make cars/technology using such source more "cool."
Petroleum is neat, it's cheap and very energy dense, but it's just not going to last forever. So using these electric cars may be the only way to well... use cars! With that, the rise of renewable energy and the inevitable super mainstream use of it may just counter the carbon footprint of electric cars.
That or we just find some new hydrocarbons and everything I just said is total bullshit.
Lol I really doubt that. Where did you read that? Is that comparison taking into account the carbon footprint of making a regular car too? did they look for the kind of energy source that Tesla factories use?
Elon Musk said from the very beginning that electric cars are better for the atmosphere. If anyone has proof of anything else, go and tell him.
Smitty Werbenjagermanjensen Elon Musk said Tesla cars are for saving the atmosphere (as we only have one).
Derick Smith No, the way to go for saving the environment is using electric cars (to avoid pollution at street level that is actually killing a lot of people) and adopting plant-based diet (to stop global warming, as the methane of the 70 billion animals of the livestock industry is 50 times worse than CO2, and the only source of pollution bad enough to cause the global warming).
And I see that thing of using classic cars a pretty bad idea. They are extremely unrecommended for having a very poor safety in comparison with today's cars. And old car would split in half in the pole crash test, while a Tesla car maintains the interior completely untouched.
vistaero but is it true that the making of a tesla car have a carbon foot print of a regular car used for 8 years ?
You should read the report on "Cleaner Cars from Cradle to Grave", it'll answer your question.
Nice video. Busted premise though. There are far more than two main factors: speed of charging (which you just mention briefly at the end), hold of charge, max discharge current, and number of cycles for life of battery come to mind immediately. Lots more. Did ya even mention the potential promise of supercapacitors? Till next time. (Hey, sorry I fart on some videos, but I was trained to do failure mode analysis.)
What about larger scale energy storage? Since many renewable energy sources can't produce energy on demand, it will need to be stored when it can be created to be used later.
Nanotechnology is the answer.
I don't think you understand what that means
ankith m - please go back to school.
This video just explained why no matter what we do, there is a physical upper limit to energy density.
the numbers given here would be the absolute maximum, where every single last atom is used perfectly to store energy - that is well beyond any "nano" technology (which in turn is just a buzzword for laymans).
nanomachines, son
Nanotechnology is a term that encompasses all physics related activity at the molecular or atomic level
This video details the physics of lithium *molecules* , therefore the video can reasonably be described as one that explains the future *nanotechnology* of batteries
The way you are using the term makes it look like nothing more than a buzzword
So yea this video basically explains the nanotech and physics of battery power and what is possible for the future in terms of technology and innovation of chemical energy storage
I was a casual like you too at some point but then I learned muh physics basics, you should too dude. Learning of what holds for our future through the basics of physics or through the conclusions of educated physicists makes one feel like a magician lol
HomeSkillenSLICE ,
What if we ditch chemical energy altogether and figure out other ways to generate energy?
then what would happen to all battery powered gadgets? Oh wait, you haven't thought about that, have you?
Well, for one, batteries are used to store energy, not to produce it.
Anyway, for something as important as energy storage, you can be sure that every possibility is explored in detail. If we use chemical batteries today, that's simply because it's the best option available.
Tell us a different way to store energy then.
Oh right, you don't know any?
Here, let me tell you a bit about physics:
there are only a very small number of ways to practically store energy.
Heat, height, springs, chemicals, electrons, speed.
heat is simply heating something up to later use a turbine or similar to generate power - a very very bad idea for a mobile device, but rather nice for solar power.
heating up
Height - lift something heavy and you store energy. But that ain't easy and doesn't store that much energy.
Springs - you know old spring-watches? you need to constantly rewind them.
electrons - like in capacitors. You can increase the energy stored by increasing the voltage or the surface area. But even the best capacitors are limited by the insulator between the surfaces and they are like 1/10th the capacity of batteries.
Speed - a flywheel or similar.
but here is the thing:
Chemical energy is just vastly better.
Lift 500kg 10 meters and you get 49kJ. That is about the same energy a smartphone battery holds.
Chemical bonds are incredible energy dense and comparatively easy to handle.
Nigga he said generate, not store.
Well, technically speaking such idea was tried, but ended up in niche application:
en.wikipedia.org/wiki/Radioisotope_thermoelectric_generator
Not sure, hover whether I'd really like a mobile phone powered with Pu-239.
Good info, thanks. What about battery changes as they are used, recharged, reused - degradation as well as effect of temperature and charge rate on long term function?
Hi Henry, have you once thought what we will do when our batteries die? Because when we're producing so many batteries, how do we recycle them? I'm a bit concerned that we will produce a lot of them and end up storing the broken one anywhere because recycling will be too expensive. Have you ever thought about this?
I guess stupid decisions about battery combinations have led to the many cases of exploding Samsung phones . . .
. . . I think.
And that's bad reference for what?
note 7 battery explode because of the rounded corner shape of the battery to fit the phone, not because of the new chemistry or some shit
mobai123 so let me get this straight... The battery exploded Because of round corners, not because of bad chemistry??..lol.... 👍ok
UnknownUser025 you replied yes to the battery exploding Because of it's shape? In other words are you telling me that with Perfect Chemistry the shape of the battery alone would have caused an explosion?
MALACHI'S DISCIPLES Well, yeah. All lithium ion batteries carry a lot of energy, and inducing a short circuit in them results in the energy being released violently. There are videos of people stabbing batteries which lead to the batteries going up in flames. In the s7's case, the short circuit was not caused by an external impact, but by a flaw in the battery's design and a lack of quality control.
When you're early and you dont know what to say....
WazzupKMS I'm glad you thought of something.
You don't have to say anything. Commenting is optional and not a requirement.
Say what you need to say!
[insert witty comment here]
It would be nice to get a copy of that periodic table, very clean looking.
I have an Anker battery pack. While they are quite heavy (probably because of the large dense cells in them, you can see whats inside in a video by JerryRigsEverything), their capacity, (Crazy 26,000mAh) and size is amazing when compared to other battery packs for a similar price and how many times they can charge your phone. Highly recommend buying one.
The fuel for the world will be Algae Bio-Diesel fuel, Noob
Can you do a video like this on the graphine battery's that are starting to come out to compare them to the ideas you go over in the video. I really wanna know if they're better and if they'll solve this problem
Funny you should mention running out of battery power during shaving. After not shaving my head for a couple months I started shaving my head earlier today and the plug/battery shaver I had, which I usually leave unplugged, and which usually starts off a little slow, just wasn't gaining power the longer it was plugged in today. It muddled through to get it 'good enough' but it was touch and go there for a bit. (After leaving it plugged in for a while it seems to have regained its old oomph. I'm not sure why, on a plug/battery hybrid you wouldn't make the plugged option powerful enough to plow through on its own.)
Anker batteries and cables rock! I've been using them for years
Can you do a video on Sodium-Ion batteries? I hear about it sometimes, but nothing more than a few articles or blogs are all I can find.
Great video
The only kind of paid promotions I enjoy x
0:27 have I already seen this video?
0:32 oh ok now it makes sense
Real Engineering best channel
GREAT VIDEO
0:11 love that Chanel!!!
It was much helpful
Sam and Niko team!!! Just came to this from their vlogs
I'm really curious what you think about non-chemical batteries, fuel cells, and supercapacitors.
Hey minutephysics, what's you're take on the solid-state, glass batteries that are supposed to be able to hold a ridiculous amount of charge AND last a lot longer? It would've been nice to see an explanation for how those work included in this video, although batteries in general still strain my comprehension.
As I recall, they're being researched by Dr. Goodenough (one of the original developers of the Lithium-ion battery) and Dr. Braga. Googling "glass battery" should bring them up well enough, though. I'd love to see an addendum discussing the difference between glass batteries and conventional batteries.
Also you need to look at the resources you need to build them, and how long they keep working
This was touched on a little in the video, but it's worth mentioning more that even the theoretical upper bounds for how energy-dense we can make rechargeable batteries is still an order of magnitude less dense than a traditional fossil fuel. In fact, a lot of the research there is not about making more efficient batteries, but using electric power to more efficiently synthesize chemicals like ethanol and butanol (e.g. www.ornl.gov/news/nano-spike-catalysts-convert-carbon-dioxide-directly-ethanol ).
Yay new video!
Loosing my wallet and my phone died. Could have done a lot with all my apps. A charger would has save me a 6 mile walk home.
Also thank you Anker for sponsoring this show. It's a great show and if you keep sponsoring him, I might move that SoundCore 2 from wishlist to cart ;)
Honestly I think powering for example:
1: A city is not only about batteries themselfs but also about how efficient is the usage of energy, you can improve energy efficiency of light bulbs, computers, elevators or even water pumps, etc. so you will not have to be able to store as much power as you would otherwise. 2: Maybe thats just my opinion but i think and honestly hope we will be able to store power in better ways then chemical batteries only ( btw i know that there are some ways of already non chemical energy storage like storing energy in spinning disks for example.) however i mean other ways which could be used if not in small devices like smartphones but at least in electric cars, by what i mean we wouldnt have those chemical limits which you mentioned.
Minutephysics, how about nanotechnology? I heard Kaku speak about basically enabling (near) infinite storage potential. It was on his video about a lightsaber i belief.
There's actually a really cool molten salt nuclear reactor battery design that can essentially provide a year's worth of energy for buildings and so forth with no moving parts (it's natural convection-based), and can be "recharged" by swapping out the fuel/fluid inside, which is pretty simple to do. If you're wanting energy on demand in fairly large quantities, you can't do better than fission!
Hey, wouldn't it be easier to store the energy using electrolysis of water and use the oxygen and hydrogen to power cars, heating houses etc? Please make a video about it!!
Brilliant!
Can you make a video explaining the difference between DC current and AC current?
0:10 Eyyyyyyyyyyyy Sam & Niko
Woah, two videos in a row about Anker. They really know how to advertise.
3:50 Ah the good old fusion fewer dream. How exactly would that solve the problems discussed in this video? The drawing suggests each car having a fusion reactor. But how small could a fusion reactor (provided we get fusion reactors to have positive net energy output) get? You spent the video answering that question for batteries but jam fusion in with an off the cuf remark? You might as well have said "unless we figure those ultra-compact nuclear fission reactors from Fallout out".
What about graphite batteries? I know they will be expensive because there still reasearching it but it can be used for everything in the future i think.
At last, someone who sees the RIGHT picture. Not the rose tinted one, where “we’ve come so far, so further progress is inevitably going to lead to nirvana”. Physical (chemical, its all the same thing in the end) limits matter; thank you - I will be using a link to this, I’m sure.
I let out a very hearty laugh when you mentioned a lithium-fluorine battery. Yeah that would be a wonderful idea...
2:37 Lit...
😂👌 💯💯💯💯 🔥🔥🔥
I have that battery pack! It's amazing!
What about pumped water storage or similar solutions, how will those play a roll in better distribution and collection of renewables'
What if we don't care about wight but about the energy, could we use heavier elements than just (Li,S,O,F) ?. More energy even if more wight.
Electrochemical batteries won't be the big solution, but something more exotic might be. I heard something about storing electrons in bulk inside of a graphene-carbon nanotube composite. Apparently it has a theoretical storage density in the gigawatt hours per kilogram, so that would be useful... Should do a video on that.
I think two main technical stakes of batteries were not discussed here.
Weight is certainly a problem but the volume inherent to the technology is extremely important too (otherwise, electrolysis and H2 would have conquered the market a long time ago with one of the greatest power to weight ratio). Making things compact is about making them also smaller in size.
The other point about democratisation of batteries is obviously the costs that can't really be put aside either but you talked about it a little in the video.
Very nice video, good on you that you credit sam and niko. They do some sweet stuff with video's
I just now realized that you and Real Engineering are different channels
What ever happened about the wonder material "Graphene" batteries, which promised to be rechargeable in minutes?
Great video, but one issue. Lithium is not very reactive but fluorine is. The reason they react so violently is Lithium has very high amounts of electromagnetic force so the much more reactive fluorine atom can "take" the lithium electron with only a lot of energy already present in the reaction.
That huge battery pack better run that single lightbulb longer than 10hrs... i have a camping fan/light that runs on 4 D-size standard batteries, and it will run longer than 10hrs... seems like that time you suggested is waaay off. Maybe the 18650s in that battery pack are low mAh, but then what is the point of having 8x of them? Anyway, i love your videos man. I hope you are making content for years to come!
Very interesting for a professional drone operator!
@minutephysics what if we decided to redefine a circle as having only 100 degrees instead of 360, how different would our clocks be?
Why is there a link to the Sam and Niko channel in the description?
I wonder what the outcome would be if graphene was substituted for graphite? I'm guessing that if could be done they might be lighter, just as stable, and the transfer of ions would be much quicker.
Yes, but How about Quantum batteries ? how would they work ? they are mentioned in the TED-Ed video about batteries
Interesting video as always.
Glad to see you included *references* in the video description.
do you ever put make up or something on your hand since its the only body part seen(usually)?
Never heard anyone talking about the theoretical endgame for batteries, but it sounds similar to moore's law in the cpu world.
question does anything truly "disappear" or does is jut change shape form and the amount of energy it has?
What about graphene? I heard about it a bit ago and haven't heard much since. Is it still a thing and would it work to replace current battery technology?
Have owned and Anker for years. Very reliable.
