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

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.

Thicker metal is copper. Black layer is cobalt and thinner foil is lithium. Is that correct???

[@dragoncloud7830]

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.

[@ElectronicsComputers]

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.

[@milvolts1]

How is it possible then to puncture positive end when its 0 volts . then miraculously there are 4.0volts?

[@paulkrush565]

​@@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.

[@drewrinker2071]

@@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

[@pedroemn]

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.

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?

[@ElectronicsComputers]

It's not completely dry but you won't see any paste or liquid either.

[@michaelvillame]

@@ElectronicsComputers ok, got it!

[@codyramos3200]

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.

[@MenkoDany]

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?

[@nicm5616]

They just stack square or rectangle sheets then assemble slightly differently.

[@theduder2617]

@@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

[@ElectronicsComputers]

The top contact is positive and the whole casing is negative.

[@xaviqq5]

it seems is other way around last one is cathode... cos cathode is side where copper is installed

[@Khabirov88]

Is it toxic? I mean should we wear mask? What ig yhe black powdery substance get in contact? Is it harmful or smething?

[@ElectronicsComputers]

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.

[@davidmoore4680]

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.

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.

@@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.

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.

[@raghvendragupta9740]

@@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
