Big Clive performs a complete teardown of a lithium-ion phone battery, examining its internal layers and protection circuitry.

You can now buy me cake and things to take apart at:- patreon.com/bigclive So this started off as just trying to see how the circuitry was mounted in a lithium cell. I should really have discharged it first as it got a bit freaky at times. But this is a total teardown. Not just cracking out the circuit board, but the whole case and then the guts of the cell too.

Why it's here

What people say. Recommended for showing the physical internal structure of lithium-ion cells and their safety components.

Big Clive does a really amazing (and dangerous) tear down of what's inside a Lithium Ion cell, in case anyone wants to see what the parts in the diagram physically look like: link to this video

On “My 2015 MacBook Pro Retina Exploded”

EgyptAir is investigating if a phone or tablet may have led to a crash of one of their jets: link There have been many devices that have come under scrutiny for their Li-Ion cells. At least few devices explode, and I'm not aware of any killing people, but many have had these meltdowns. Big Clive successfully took one apart without it going boomb if anyone is interested in what's inside of them: link to this video

On “Samsung Galaxy Note 7 owners told to turn off device”

> The thinner the battery, the closer the positive and negative terminals are. Absolutely false. All lithium ion batteries are made of 4 paper thin layers: two electrodes and two separators. These are cut in narrow strips and folded on themselves many times over, even in a thin battery. A thinner battery will simply have fewer folds. The distance between the two electrodes is given by the thickness of the separators and it has nothing to do with the thickness of the cell. Here's a teardown: link to this video (possibly NSFW-ish language).

…alone 1. Still non-zero chance, don't open them! Primary/metal lithium batteries, on the other hand, are much more likely to burst into flames when opened. Notably, lithium-iron disulfide (AA/AAA "alkaline replacement") cells are notorious to do that just from air exposure, even if one is very careful to not short/pierce anything. 0 link 1 link to this video…
