This is the first video I've found on this topic with sound chemistry and decent results with a real yield. Thank you for documenting your process and translating it to English, much appreciated.
A video with an important question posed the beginning. With many governments pushing for a full switch to EVs, it's important to ask what can be done with the e-waste they will create. That's ignoring issues with the availability of raw materials and emissions produced from their production.
🤦🏻♀️ EV's are only being pushed upon us because politicians are universally corrupt and green tech is big, big money. Green initiatives/technology exist for the sole purpose of making money and the 'green' phenomena has nothing do with 'saving the planet' and never has. Oh and E-waste recycling is a total lie, so don't expect anyone to do anything about it other than sweep it under the carpet for as many decades as can be got away with. 😹
E-waste is a resource. All those batteries contain highly refined metals of known concentrations that are much easier to extract than from minerals. Basically baterries are like high grade ore.
So after all that, the commercial recycling of lithium batteries is actually just melting them into an alloy used for what other purposes? Does not sound too green to me unless I missed something.
@Andrynor Ω Most of the components of "green" wind turbines are not recycleable and will end in landfills. I suspect the same is true of solar cells. This "green clean" narrative is mainly BS. But the uninformed buy into it and feel good about themselves.
@Andrynor Ω it is pretty frustrating yeah, just today i was watching Real Time with Bill Maher, he had a guest on that said, unfortunately because of a handful of nuclear accidents, people mistakenly think that nuclear energy is less safe than coal. Coal is polluting us every day with every breath we take, but because it doesn't create headlines of terrible disasters, people don't realize it as the killer that it is, it kills more people very year than covid has so far. I mean, that in itself is not a shocking revelation, we all kinda knew this, but what i find frustrating is that Bill doesn't jump in on the nuclear, there was no response, he only wanted to hear about coal killing more than covid, but it does not seem that he is for nuclear energy. Nuclear energy is like airplanes, if one or two go down, people get scared and will avoid it like the plague, but the actual plague, eh, who cares.
I think the reason why people are so scared of nuclear is because we as citizens don't control energy production and "green" energy is a nice-sounding alternative. With something as potentially destructive as uranium/plutonium reactors its easy to see why people are scared. This was pretty apparent when the public learned that thorium could be used in reactors.
This is one of your best videos yet. Thanks. And I enjoyed it because I am in the middle of a project doing exactly the same thing. Those cylindrical batteries are really tough!

The methods and the beginnings of the infrastructure are set up for Li-Ion recycling, but car batteries have proven to be much longer lived than manufacturers expected since they are much better managed than laptop and phone batteries. And then they have a second life as stationary storage.
As somebody who is dealing daily with Li-Ion batteries, you are very brave to dismantle them like this. There could be a fire easily. On the other hand, love the research.
I was thinking about that yesterday but they have holes only small enough for lithium ions which are very small but hydrogen will still get through i think . Amazing material engineering in it self !
Not sure why one wouldnt use Ceramic for semi permeable membranes. The work great and mixing is minimal at best and can be all but mitigated with the most minor effort of loading the membrane first in which you basically pump it full of the ions you expect to come from the cell so what you get is ion migration but no actual mixing of the two fluids.
@@seditt5146 ceramic is only usable for some processes and can be degraded by others. Partially dechlorinated PVC is generally superior, and also not too hard to make.
Yes, I have used the plastic film membranes out of larger lithium polymer battery's for remote control toys , planes etc. I took a plastic vessel and cut a square hole in it, about 15 square centimeters and then sealed the hole with a sheet of the battery separator, I used silicone glue to hold it over the square hole, with about a centimeter of overlap between the vessel plastic and the separator, so it was basically like a sealed window. The rest is fairly obvious. The plastic separator material is just like ordinary plastic, fairly tough stuff, not at all fragile. Some cautions though, I found that pushing more than around 6 amps across can weaken it to the point it leaks from tiny pores forming in it, heat is an issue, an active cooling system is needed when pushing high current.
Actually acting more like a big electrolytic capacitors- a slow leak capacitor. I love your channel and learn an amazing amount from your channel and videos. Absolutely wonderful‼️
And just yesterday I was wondering how to recover the lithium from these batteries. Given the chemicals, energy, and time required it hardly seems worth it for a few grams of metal. Which is why I expect them all to become landfill for the foreseeable future.
Sometime I don't understand the trend for big electric cars, when something like a closed golf car could be a lot more ecological and make more sense for small everyday travel. I've seen video of such a car sold by Chinese for 600$.
I remember when I took apart a charged lithium ion battery the anode (copper sheet) was getting warm to the touch indicating that there was lithium in the graphite. It was oxidising in air.
Could you have taken a different approach @11:11 ? Instead of using NaOH you could have started with HCl(aq) to transfer the different ions (Al3+, Li+, Co2+) into solution and, after vacuum filtering, let them cristalyze. Lithium chloride has a solubility of around 80 g/l , whereas cobalt(II)chloride of 529 g/l , aluminium chloride of 458 g/l each at 20°C. So you could filter lithium chloride out quite well, before the others start to cristallyze.
Very interesting. I have a feeling a punch is used to push the jellroll out after both ends are cut off on a auto bandsaw that is sprayed with cooland to prevent thermal runaway ! A big conveyor belt is full of cells getting the top and bottom cut !
I was looking for the formula of the lithium battery, but I did not find it, now you have discovered the secret of this phenomenon, thank you very much and great channel😍❤
Yeah as you discovered here, one needs to use relatively sharp pipe cutters and cut EXTREMELY slowly else it binds the inside. When done really slowly that will not be so much of a problem.

Great show. This reminds me the 1950s lead acid batteries and a removable top and you could unbolt a cell then replace it. Not as light but a lot more servicable.
Remember folks, there are two additional factors to consider before dismantling batteries. One is just because it can output the amps needed for your device doesn't mean its drained. Two is surface charge exists, ground the batteries with a specialized device for your cells, using a ground rod can cause thermal runaway.
Three is to use a plastic or wooden tool to remove the spot welded strips from the cells. This way you don't arc the cell even if there is or isn't any charge in it. Tip: Put some heat shrink around the tip of some needle nose pliers to help remove the strips and not arc the cell.
One of your better videos and that it saying a lot! Don't sell yourself short about yield. You actually achieved a yield about twice what you thought you did at 18:40 At 17:50 you say that you leave about half of that superfine precipitate behind to avoid burning out your vacuum pump so the yield of Lithium carbonate is the yield from about 5 cells not the ten you started with.
Well you only filtered half the cobalt nickel lithium solution, so you would have gotten closer to 13g. I always lose a lot of product in the filter discs because I am too lazy to scrape it all off. Assuming you did the same you could probably have gotten closer to 14 total. I think a few steps could be improved at scale and also cheaper reactions used, and then it would be worth recycling.
Great video! very interesting Thoisoi2 !! Looks like a very, very complicated process nevertheless. No wonder LiOn batteries get thrown away. Personally, I can't find a single place in my region that takes them for recycling. The single company I've found that will take them charges a processing fee leading me to conclude that is not economically feasible for them to do it (yet). One would think that with all this green push the manufacturers would've come up with a practical methods of recycling lion batteries, but no. I fear this will be a big issue soon and we are literaly trading fossil fuel energy independence for rare-earth dependence mostly coming from China.
@@Fred82ndAbn basically at some point if we can't find better methods, then stripping asteroids and planets in the solar system of materials might be the only solution in a long while. It'd be great if we made more breakthroughs in nuclear energy it's by far the best source of fuel and we can literally solve the coming water crises by using the passive heat from nuclear reactors to boil and make ocean water drinkable which has been done already and shown to be very effective
So where does the economically FEASIBLE Lithium occur? Afganistan and the Atacama as far as I know.... and the excrements od psychotics prescribed the carbonate salts🙄😆
@16:50 It's not primarily for cost-cutting, rather, nickel oxide can actually withstand a higher current as well as pack more lithium ions for higher capacity than cobalt oxide. (Manganese is even better at handling high current, at the expense of capacity.)
Interesting video, but you should look at Tesla's recycling process. No need to wait a decade for efficient recycling because they have solved it already. The trick is to not restore the substances into they element form but isolate and reuse materials as they are. Most degredation is caused by mechanical cracking of graphite or silicon, which isolates part of the material from charging cycle. Chemically it is still intact. Sometimes there are dendrite Chrystal's from metallic lithium but typically it indicates a battery abuse like too deep cycles or charging in cold.
you can reuse cycled batteries for lower power consuming processes, if you drain a used battery slowly enough, you will get nearly the same capacity, it's just that internal resistance rises, the method of recycling in the video is only needed after the batteries are completely unusable most batteries are not fully cycled, for example in a laptop, if you use the battery for long enough, one of the cells or the bms might break and the rest of the cells are sent to recycling even though they can be reused
A better term for your "accumulator" is a cell, cells comprise a battery. Often even individual cells like 18650 cells are also still called batteries (albeit technically incorrectly) especially if used individually instead of part of a pack of cells.
oh man that accent! i've been trying to master it for like 2 years and still can't even come close i love it it's hilarious!!! especially with the terrible dubbing mixed with great content. you nailed it, bravo dude. my hats off to you sir!
Nice experiment! So it sounds like the most economical way of recycling these now is freezing them, then shred and pulverize. Easier to separate the raw elements that way apparently, and freezing the batteries is easy and is supposed to make sure no reactions will occur while shredding. Now you have high quality already refined rare earth materials that just need to be separated out. This is what I have seen recently anyway and obviously has to be done in large scale with the right equipment. Redwood Recycling says they can recover 90% of usable materials already. If true, that's pretty good. If they really have this figured out, there's going to be big money in recycling this stuff when it catches on.
If you just want to recycle the battery into a new battery, you can use the same ratio of metal oxides as the original, so you don't need to separate each metal. I would try to skip the sulfuric acid step and burn off the carbon in a hot, high oxygen environment. Maybe a good application for a tube furnace. There might be some lithium in the graphite coating on the copper anode as well, but I'm not sure if it would be enough to worry about. That might depend on whether it's fully discharged.
Sounds like a great research project. Target minimal processing over purification for a new product. Surely, surely, oodles of people are working on that. Surely?? A big hurdle would be to ensure end-of-life returns to manufacturer. I've heard of only one company that has that goal.
@@chrisking7603 The recycling pipeline would at least need a way to separate different brands or compositions of batteries. It may be possible robotically to flick them into different bins based on the print, if it's still readable. Or you could just break them all down, measure what you get, and add enough new material to get the ratio of metals you need. In any case, the main thing is just getting people to recycle their batteries, however it goes from there.
Really well done man. You just explained a very complex scientific idea to a complete dummy (me) in your second language. Takes a really smart dude to do that. Sports figures and movie stars don't impress me...smart people like you do. Please keep up the great work my friend.
This is why I'm surprised we aren't switching to graphene batteries. They are SO much easier to recycle and they hold a lot more (and charge faster too).
i think the industrial recycling version of this will simply grind them up in an argon atmosphere (to skip the need to discharge them and limit the fire) and then a magnet removes the steel casing bits and other steps removing the lithium/cobalt/copper/etc. Of course given the difficulty and chemical processing needed unless lithium prices rise high enough to make recycling profitable no one it's going to spend money on trying to recycle them if it's cheaper to simply ship it as e-waste to Africa. I imagine some sort of industrial electrolysis/centrifuges will make it more practical from a chemical use standpoint, though on a large scale that will rival aluminum production in electriciy use (kinda pointless if coal is still the main fuel for that, might as well just go back to coal-powered steam boilers in cars and skip the power grid energy loss).
To anyone replicating this: although those high-current, medium-capacity batteries extracted from the Hilti battery pack were probably indeed an NMC chemistry (that is, lithium-nickel-manganese-cobalt oxide), the more recent 3000mAh and higher capacity cells are usually NCA, which also contains aluminum.
You are among my favorite educators. Thank you for you high level content. I respect your service to our scientific knowledge. Good Fortunes Great Successes and Many Blessings.
I'd suggest accumulating all the spent lithium cells possible, as quickly as possible. The world as a whole is quickly becoming aware of the fact that our ability to produce lithium at maximum capacity will be overshot by our consumption (Demand) by about 100% per year over the next 5 years... Whomever discovers a viable (Effiecient) way to recycle dead lithium cells will be wealthy beyond measure, without a doubt. And those who tried but had not yet succeeded in developing a procedure to do so, will have quite a valuable store of test materials leftover.
Yea, those pipe cutters crimp the tube and lock the roll in. I use sidecutters to clip the top off and then peel the casing down until it's loose. Anyone planning on doing that, be prepared to lose some blood. It's inevitable.

So where does the economically FEASIBLE Lithium occur? Afganistan and the Atacama as far as I know.... and the excrements od psychotics prescribed the carbonate salts🙄😆
Coming from China & South America from mines that have a negative impact on people working in them and on the environment.
@16:50 It's not primarily for cost-cutting, rather, nickel oxide can actually withstand a higher current as well as pack more lithium ions for higher capacity than cobalt oxide. (Manganese is even better at handling high current, at the expense of capacity.)
This was amazing. Subbed. Got me really thinking and yeah, what a nightmare this is to work with after these batteries lives are done.
Interesting video, but you should look at Tesla's recycling process. No need to wait a decade for efficient recycling because they have solved it already.
The trick is to not restore the substances into they element form but isolate and reuse materials as they are. Most degredation is caused by mechanical cracking of graphite or silicon, which isolates part of the material from charging cycle. Chemically it is still intact. Sometimes there are dendrite Chrystal's from metallic lithium but typically it indicates a battery abuse like too deep cycles or charging in cold.
always interesting to watch your videos
I do not understand all of the chemistry but I enjoy watching you do it.
Love these videos. Keep up the good work
19:14 Charge $2 extra for a spoon of that guacamole and you'll make up the difference in lost Lithium.
Fantastic video! The topic is super interesting and there are companies that are recycling batteries on commercial scale. Best regards!
I want to thank you for answering the questions I've always had but people are too afraid to find out
you can reuse cycled batteries for lower power consuming processes, if you drain a used battery slowly enough, you will get nearly the same capacity, it's just that internal resistance rises, the method of recycling in the video is only needed after the batteries are completely unusable
most batteries are not fully cycled, for example in a laptop, if you use the battery for long enough, one of the cells or the bms might break and the rest of the cells are sent to recycling even though they can be reused
It was cool to see you as a "regular" dude at the beginning! Great Video!
A better term for your "accumulator" is a cell, cells comprise a battery. Often even individual cells like 18650 cells are also still called batteries (albeit technically incorrectly) especially if used individually instead of part of a pack of cells.
An accumulator stores energy fyi.
oh man that accent! i've been trying to master it for like 2 years and still can't even come close i love it it's hilarious!!! especially with the terrible dubbing mixed with great content. you nailed it, bravo dude. my hats off to you sir!
Excellent video. Seeing science in action on real world problems is very interesting. Thank you for the video.
great experiment...even the goal is not fully reached but it really highlight the process
Ok, for your next project, separate PU239 from spent uranium fuel rods.
Lol
One of the very few Channels I enjoyed watching. 👏👏
🍻 cheers from Oregon! Thanks for the videos!!
Chemistry is awesome! Thanks for the video
Nice experiment! So it sounds like the most economical way of recycling these now is freezing them, then shred and pulverize. Easier to separate the raw elements that way apparently, and freezing the batteries is easy and is supposed to make sure no reactions will occur while shredding.
Now you have high quality already refined rare earth materials that just need to be separated out. This is what I have seen recently anyway and obviously has to be done in large scale with the right equipment. Redwood Recycling says they can recover 90% of usable materials already. If true, that's pretty good.
If they really have this figured out, there's going to be big money in recycling this stuff when it catches on.
I love your videos so so much! Is there a chance we could get a version of the video with the original audio with subtitles?
His main channel is Thoisoi and is in Russian. Go watch it if you like. 🤷♂️
@@Burnt_Gerbil thanks! Does it have subtitles, though?
@@GuidoPerdomo - Nope. Either watch this video with English captions or the other one in Russian.
A great idea
If you just want to recycle the battery into a new battery, you can use the same ratio of metal oxides as the original, so you don't need to separate each metal. I would try to skip the sulfuric acid step and burn off the carbon in a hot, high oxygen environment. Maybe a good application for a tube furnace. There might be some lithium in the graphite coating on the copper anode as well, but I'm not sure if it would be enough to worry about. That might depend on whether it's fully discharged.
Sounds like a great research project. Target minimal processing over purification for a new product. Surely, surely, oodles of people are working on that. Surely?? A big hurdle would be to ensure end-of-life returns to manufacturer. I've heard of only one company that has that goal.
@@chrisking7603 The recycling pipeline would at least need a way to separate different brands or compositions of batteries. It may be possible robotically to flick them into different bins based on the print, if it's still readable. Or you could just break them all down, measure what you get, and add enough new material to get the ratio of metals you need. In any case, the main thing is just getting people to recycle their batteries, however it goes from there.
The translator is using a fake accent and I'm here for it.
Really well done man. You just explained a very complex scientific idea to a complete dummy (me) in your second language. Takes a really smart dude to do that. Sports figures and movie stars don't impress me...smart people like you do. Please keep up the great work my friend.
Very well done, excellent analysis and conclusion, thumbs up and subscribed!
Best video i found for my research purpose 🙂, congrats bro you got new subscriber!!
18:50 Did you verify that this white powder in fact contains lithium? (e.g. with a flame test or something)
This is why I'm surprised we aren't switching to graphene batteries. They are SO much easier to recycle and they hold a lot more (and charge faster too).
Thanks, that was indeed well put together.
I LOVE THIS CHANNEL!
Thanks very much bro, priviet! we needed a good video like this, finally!
wow, that is some deep research, thank you!
I'm curious how the process would differ for LiPo batteries
very similar to mine but I forgot a lot of details. Your videos are perfect
You are a seriously great scientist and teacher.
i think the industrial recycling version of this will simply grind them up in an argon atmosphere (to skip the need to discharge them and limit the fire) and then a magnet removes the steel casing bits and other steps removing the lithium/cobalt/copper/etc. Of course given the difficulty and chemical processing needed unless lithium prices rise high enough to make recycling profitable no one it's going to spend money on trying to recycle them if it's cheaper to simply ship it as e-waste to Africa. I imagine some sort of industrial electrolysis/centrifuges will make it more practical from a chemical use standpoint, though on a large scale that will rival aluminum production in electriciy use (kinda pointless if coal is still the main fuel for that, might as well just go back to coal-powered steam boilers in cars and skip the power grid energy loss).
To anyone replicating this: although those high-current, medium-capacity batteries extracted from the Hilti battery pack were probably indeed an NMC chemistry (that is, lithium-nickel-manganese-cobalt oxide), the more recent 3000mAh and higher capacity cells are usually NCA, which also contains aluminum.
Woud be interesting to know how the lithium isotope composition is in this recovered lithium. Is it possible to isolate lithium 6 from the batteries?
Thank you thoisoi! Recycling is the ultimate graal for tomorow. Great video. hope somebody find the right way. I 'll be the ultimate hero.
I love this channel! I love his accent too!
I don't like the accent
Can u show us how to get différents chemicals like lithium in batteries, or lanthanides in lighters, or potassium chlorine from salt
potassium chlorine from salt sounds really hard to separate
@@陳柏廷-u5p not that hard bcz at boilling température of water 100°c the solubility of KCl is bigger than that of NaCl
One of the best videos I have watched
Love your vid so much :)
Sir can you please tell us how to separate the Ni and Co from that paste like substance.🙏
Lithium is as common as dirt. Wouldn't it be more valuable to extract the cobalt?
Great video. Nice work !!
Thank you , Mr.Scientist , I am enlightened.
We would be laughing if we could efficiency recycle Lithium from batteries. Your methods are precise and clear. Thanks for this video.
Very enjoyable.
Thanks for the upload ✌️
You are among my favorite educators. Thank you for you high level content. I respect your service to our scientific knowledge. Good Fortunes Great Successes and Many Blessings.
I'd suggest accumulating all the spent lithium cells possible, as quickly as possible. The world as a whole is quickly becoming aware of the fact that our ability to produce lithium at maximum capacity will be overshot by our consumption (Demand) by about 100% per year over the next 5 years... Whomever discovers a viable (Effiecient) way to recycle dead lithium cells will be wealthy beyond measure, without a doubt.
And those who tried but had not yet succeeded in developing a procedure to do so, will have quite a valuable store of test materials leftover.
These guys are the real deal. 😂😂😂 They specifically did what the warning ⚠️ ⛔️ told them not to do.
This guy is so clever that he speaks in cursive English
underrated comment alert- I told my mom your joke and she laughed :D
For the penultimate step, where you added NaOH and Co and Ni separated .... is it possible to use LiOH instead?
Congratulations for not giving up after obtaining the green solution :)
Oh and for filtering the green-paste solution you should look for proper dissolvent I think :) Just need to look in the tables :)
Yea, those pipe cutters crimp the tube and lock the roll in. I use sidecutters to clip the top off and then peel the casing down until it's loose. Anyone planning on doing that, be prepared to lose some blood. It's inevitable.
