My exacto knife wounds opened back up just from watching this :o
No kidding, some gloves are cheap insurance.
maybe it was some suicide vid
Same.
This comment wins.
I gave a thumbs up...they might need an extra finger by now.
Aside from the substances used, the layout is pretty ancient. The battery really haven't changed an awful lot since the earlist cells. To think the bigger batteries out there are composed of units like this. So much potential for savings.
if you dissolve this lithium in heavy water do you get lithium deuteride instead of hydroxide? how well does lithium deuteride work for batteries i know 6 and 7 work for nuclear reactors
🤯🤯🤯🤯@@Aaron-zu3xn
human are genius just 2 sheet a 'paper' can produce 4.2V power
You don't know what is on the paper it is carbon and copper so it can produce upto 5 volta
Aluminum and copper not a carbon😅
@@Infinity-electronic o sorry
The genious was Alexander Volta we must remember that !. Up to now are modifications improved
The battery has been around for thousands of years. Reference Baghdad batteries.
man that razor knife really went the distance, I'm lucky if mine cuts tape half the time but MOSTLY my thumb.
I watched the video over I see now you had to break the razor a few times...I was like where did he find that razor!
This video helped me understand how a knife like this works...
Wow, i liked your German accent. Keep it up
Thank alot for this video it will help me alot with my project ❤️❤️
You are welcome 😊
Good video, I was a bit concerned about the way you used the knife.
Ok, now I realised that Li-ion batteries are pretty 'dry'.
Not even charged
It's just paper covered with another paper by another paper
Good job!
Thank you!
Damn, that's a really risky way of using such a sharp tool. I've got some scars from wounds opened by razors that I held like you did. You're lucky you didn't cut yourself, stitching fingers and thumbs hurts a lot more than softer body parts.
I wanted to get a closer look at the circuitry you skipped so quickly!
awsom
how
much. for. batry
I've been looking into 18650 batteries. Seen too many explosion videos. You scared me a bit when you stuck that X-Acto in there haha.
If you fully discharge Li-Ion battery then you can safely tear it down. When I tried the same with fully charged one it produces terrible chemical smoke but no fire or explosions at all.
How is it possible then to puncture positive end when its 0 volts . then miraculously there are 4.0volts?
@@milvolts1 Yes, 18650s can read 0 volts and have a full charge when the CID is popped. You have to check the cell with an ohm meter first to be safe.
@@milvolts1 Yes it's a CID. It's basically a fuse that disconnects the positive at the top of the can if the gas is inside get too much pressure. So essentially all you're doing is pushing that fuse back down
Thicker metal is copper. Black layer is cobalt and thinner foil is lithium. Is that correct???
A notice:Always wear gloves and glasses,to an larger extand a mask because of the lithiumhexafluorphosphate
Unless you are an absolute expert electrician or battery technician I would absolutely avoid doing this. Major electrical, explosion, and fire risk.
If the battery is fully discharged to 0-2 volts, it's totally safe. Otherwise, you're right, it can be very dangerous.
@@ElectronicsComputers Yes yes, I’m just putting this out there for non techies. I could imagine a normie seeing this and trying it on a partially charged cell 😅
fascinating
Thanks!
@@ElectronicsComputers So I had one of those Black and Deck handvacuums stop recharging on me. So I bought a $125 Hercules 5 amp 1/2 gallon cordless hand vacuum - so much better. So then I took apart the Black and Decker to recycle the lithium batteries. 3 cells. I was scared since I didn't know what would happen. I cut the wires and then I tried to remove the circuit board that was soldered on. Suddenly smoke and spark and nasty smell - so I obviously discharged one of the cells. I had forgotten to discharge the batteries since that Black and Decker kept turning off right away - not sure if it was a circuit board problem or just the batteries overused. But I know that is routine for those small handheld vacs with the recharging batteries hard-wired into them - not replaceable - they just run down real fast. So now I have the 3 lithium cells in a plastic bag and that in a plastic bucket - waiting to be driven to the recycling center. I'm not sure the best thing to do - if the wires touched maybe it will melt down another battery or something. hmm. But from your vid - it seems it will not explode - just smoke and sort of burn itself off from within like spontaneous combustion of a human.
Good info
Glad it was helpful!
I have a novel question - could you lay there layers and make holes (*adding heat insulating coating covering everything except the holes, and some non-electrical but heat transfering coating insnide the holes at the last stage) for a coolant to flow through them to make a large rectangular battery? The goal being getting more battery density for extremely large batteries (solar batteries, car batteries). I can't imagine the current way of stacking a tonne of cylindrical batteries wrapped in a heat insulating material is better?
it seems is other way around last one is cathode... cos cathode is side where copper is installed
Your background music sounds so much like Buck Rogers by Feeder.
I wonder how could you understand this is LiNiMnCo cathode material? As I see, haven't taken analysis on the cathode material.
yours was dry inside....strangely mine started leaking clear liquid when i peeled off the spot welded tab - guess it took out some of the original material too. Smelled solvent-like.
I have disassembled a bunch of different Li-Ion batteries but never seen any liquids even in pouch type cells.
I have disassembled a bunch of different Li-Ion batteries but never seen any liquids even in pouch type cells.
mine also leaking akin of burned smelly liquid
@@ElectronicsComputers
They probably shorted electrodes which were not completely discharged.
You did not short your electrodes.
It is also possible their cells were overcharged or over discharged, both conditions capable of causing the same reaction.
I can assure everyone that 18650s' are very capable of leaking. All lithium-ion cells are capable of leaking.
What they were seeing and smelling was hydrofluoric acid. (Hydrogen fluoride + water)
A highly toxic chemical created in the following chemical reaction process.
LiPF6 → LiF + PF5
PF5+H2O → POF3 + 2HF
Li-ions leak when they short or overcharge and get punctured. My dad is really unsafe with batteries, so I've seen a lot of messy things and learned my own safety. @@rickyrustan819
Thank you for your good video. Can i buy it(disassembled EoL lithium ion battery)?
Just make it yourself. But first completely discharge it.
I have a question the shell of the battery insulated? Or does need to conduct electricity
What I mean is the whole casing conducting electricity or only the top tip?
The top contact is positive and the whole casing is negative.
hi, nice and informative videos. I am just curious, what about opening it in fully charged mode? Is there still some paste like alkaline batteries or almost completely dry except with that toxic gas emission?
It's not completely dry but you won't see any paste or liquid either.
@@ElectronicsComputers ok, got it!
It won't possible blow up in your hands when it's fully charged ..make sure you have battery on the carpet or couch so it can't spark with anything when trying to open battery with a sharp pointy object doing a thrusting stabbing motion with it.
It would explode if you trued to cut it open when charged
@@Jmandude5 No. It might catch fire.
so the "lithium" is just a coated? not an actual lithium foil? Linicomno2? you sure bout that?
In these batteries yes that's what it is. In disposable lithium batteries you generally have a solid foil of metallic lithium though.
Why don’t they use 1% gold in the cathode?
It all comes down to manufacturing cost, you obviously don't want to spend a lot of money on something which doesn't necessarily demand utmost efficiency
I had ons of these and it completey infladed
What happen if i remove a lithium battery cote .. Is't bad idea or there is no problem doing that ?
Depends on where it's installed and what it may touch.
@@ElectronicsComputers Can you please explain to me briefly what's the function of the first layer ( The blue one ).. Thank you
That’s just the coating, the entire battery except for the small dot at the one end is technically the “negative” part of the battery. The small dot with the insulator around it is the “positive. The coating just helps to make sure you don’t accidentally short the positive to the negative.
@@davidmoore4680 Thank you
What’s that black stuff on it ?
Graphite
@@ElectronicsComputers thanks
what is the effect when opening it without safety gloves .it's dangerous?
You don't want any chemicals on your hands.
lithium and sweaty hands go hand in hand.
Don't you have a frikin dremal man because you worry me with that knife
ok put it back together now
What is artificial graphite?
Artificial graphite, is a man-made form of carbon that is used as an anode material in lithium-ion batteries. Artificial graphite is produced by high-temperature treatment of carbon materials such as petroleum coke, coal-tar pitch, or other carbon-rich materials.
@@ElectronicsComputers thanks
Is it toxic? I mean should we wear mask? What ig yhe black powdery substance get in contact? Is it harmful or smething?
yes and no... There are foil and plastic strips inside. The black stuff is graphite and some chemicals. There's no acid or something that can damage your skin... When the battery is fully discharged it's completely safe to disassemble. It's not gonna ignite or produce smoke. But if you open fresh fully charges cell then get ready for white smoke and toxic fumes. So, discharge it with a lamp, resistor or whatever you have to load the battery.
@@ElectronicsComputers oh thanks for the reply. Really good to be aware of dangers before undertaking any battery dismantling.
So nervous that he might cut his finger
I'm very careful with sharp tools even though it doesn't look like that.
Thought it would be more "gold" in there, keep digging.
they. stop. mking. shem. with. lead. rods. why?
cost. of.batry
Now put it back together and flush it
what is the outer metal casing made from?
It's made from nickel-plated steel.
❤️❤️❤️❤️❤️🇧🇩🇧🇩🇧🇩🇧🇩🇧🇩🇧🇩 Bangladesh
Now put it back
Can I ask why there is no liquid inside the battery?
There's no any liquid inside. Actually when you disassemble new Li-Ion batteries you'll see some gel polymer electrolyte but definitely not a liquid one.
@@ElectronicsComputers Lithium-ion battery contains liquid electrolyte for NMC, NCA, and LFP chemistries. When you open it this will evaporate very quickly so you can not see. If you want to see that then you just cut the cell from top and bottom and put in centrifuge at 10k RPM for 10 minutes you will find around 2-3 ml of electrolyte in 18650 size cell.
But in LIB's they say that the electrolyte is liquid.. so are these different, I'm confused b/w LIB's and solid state lithium batteries
Cool
thanks!
So its just a magic scroll huh
Where's the electrolyte?
It barely noticeable on the foil.
😊😊😊
It looks dry but my lithium cell is leaky should I open it
Don't open it!
@@ElectronicsComputers so how to dispose it living in a third world country
@@fortunedecoder9344 give it to first world countries we recycle them
Which brand knife are you using?? I wants to purchase it.
Something like this I believe: amzn.to/3rHplBL
damn and these things can burn or explode lol
Only when fully charged
Where is the lithium or am I blind?
Lithium is a part of metal oxide which is applied onto the plastic separator. that separator act as a protection layer in case if the graphite layer will be damaged due to high temperature.
@@ElectronicsComputers Thanks!
Laptop battery pack?
That cell was from some HP battery pack.
How do you get the mAh and amp?
Is this dangerous to take the Lithium-Ion battery apart?
If the Li-ion battery is completely discharged then no. Otherwise it can Catch Fire.
@@ElectronicsComputers
Thank you for your tutorial and I have successfully disassemble a Li-ion battery today!
@@yuhaohan1451 I'm happy to help!
@@ElectronicsComputers what about if it contains an electrolyte
cringe at 0:17! that hyper extension 😝
1:15 Actually, you have that statement wrong, it is the reverse of what you said, the plastic membrane allows electric conduction, but does not allow the Lithium or Iron ions to travel across, if it did, the battery would not be able to be recharged !
Aren't they just AA batteries in disguise ?
Disassembly? Should be Destroy a lithium battery!
anyways, you can see what's inside of it and how all the parts put together.
its easy to pull the razor into ur thumb like that
wakeupreallifealive and 139th like and 17th comment!!!!!!!!!!!
you are brave lol
Thanks!
I tried it, why does it smell so bad
That's how a Li-Ion battery smells inside.
@@ElectronicsComputers well if I bymistakely consumed it, will something happen😅
@@asmikatke same😢😢
dumy
Do not do this at home!
Duhhh.. you do it at someone else's home.
This is horrifically reckless.
