The vent is for venting gasses when charging and discharging. The pressure when the things explode, is too much for the tiny vent holes. The whole battery swells, then the case bursts and a fireball ensues.

@@zyeborm Gah, comment mix-up with initial response (deleted and posted correct response). I'm well aware that lipoly cells are flammable. But these aren't lipos, they're NMC cells (aka "normal lithium ion" in your words), which are also potentially flammable but are generally packaged in such a way that they combust fairly slowly with specially designed pressure release break points and such. Notably, electrolytic caps *also* fail explosively, and as such the casings they use *also* have pressure releases in a similar vein to metal cased NMC cells. That's the point I was making, that these capacitor casings are presumably actually pretty decent substitutes since they have similar design requirements

Thanks Clive, lovely stuff as always and, after reading the comments, I feel right at home here. Many, many, many happy hours in the 70's with homemade black power until the local chemist figured out what we were doing and banned us from the shop. Not to be out manoeuvred, I continued my pyromaniac pursuits by simply sending Granny in for the 2lbs bags of Sulfur and Saltpeter. Never did quite get the mix right as there was often a plastic-like residue left after combustion, probably too much sulfur I guess. Made lovely rocket fuel but no good for bangers. Biggest mishap was allowing a friend to bend some glass rods using a spirit burner on the same chest freezer (Mum's) I was mixing on. Burned his lip while trying to blow on the hot glass and dropped it in the plastic mixing bowel. There must have been half a pound of the stuff that went up with more smoke than I have ever seen before or since. What fun... still got all 9 finger and 8 toes though so came through all that, and more, without any major trauma🤞 FYI, the rockets were fused with salvaged cordite taken from a bunch of 1939/40 303 rounds found with a metal detector. When not compressed they used to give you a good 2 or 3 seconds to retire to a "safe" distance 🤣🤣🤣 Cheers all, thanks for the memories 🍺

⁠​⁠​⁠@@darrylkinslow5613 These capacitor style batteries are much smaller than 18650s. They're also generally put in disposable devices. Given that, it's pretty fair to call 1000mAh a whopping amount. Also your numbers are way off. The max capacity for an 18650 is about 3600mAh. Anything that claims to be much larger is most likely fake. As for charge circuitry using half the power of the battery if you tried to use it to charge a smartphone, that's also an overestimate. The switching regulator to boost the voltage from the battery to 5V (for USB) should be close to 90% efficient. Modern phones also use switching regulators to drop back down to the charging voltage, which should also be close to 90% efficient. The actual battery charging process is also very efficient with modern cells, so I'd expect maybe 25% losses or so. EDIT: well, thinking a little more, if you're trying to do fast charging at higher currents it might be more inefficient and closer to 50% losses as you were saying. But 5V + 500mA should be pretty efficient.

​Ahhh the memories ... investigating battery internals... and more. ...Half a dozen discarded car batteries in series and a couple of the carbon rods from those ancient massive carbon zinc phone batteries (Eveready No. 6), was rather spectacular (even in daylight) when an arc was drawn. Lotsa light, heat, smoke, superficial burns and singed things. And yes we had the equivalent of the E.C. pie dish for flaming bits and pieces. Heaven knows what the neighbors thought. Gave a bit of a tingle if hands wet and mishandled. Added dubious bonus was occasionally a freshly overcharged battery would be ignited by sparks and spray acid around. (Had to keep leads as short as possible, so car batteries, carbon rods and user all in close proximity) Clothing with numerous holes from sparks and acid raised parental eyebrows. Survived. (& Learnt a lot of practical things that added to a really useful career)

It'll be about the same for a very long time I think. About the only different type of battery in the last few hundred years since Volta is the liquid metal/molten salt batteries. They use different density metals and salts to make up the cell, heat the whole thing to red hot and let gravity sort it out. It's still about the same structure is just all liquid and red hot lol. Aluminium air batteries might count as different too but they aren't rechargeable so I don't know if they count

Another thing is that the demand for batteries for smart devices has been relatively constant over the last years, while the demand for EV batteries *exploded*, so the impact and scale of child labor has only gotten worse.

Easy to get the lithium strip w/o discharging battery. Use a small tube cutter to penetrate the metal. Immerse it in a hydrocarbon to keep it from reacting (such as naphtha, hexane, or even gasoline). Use 2 pairs of plyers to pull the cut tube apart. With some practice, you can do it in under 1 minute.

With the use of the casing of an electrolytic capacitor, the cell can build up some internal pressure without expanding. On the other side of things, when there is too much pressure, it explodes like an electrolytic capacitor when the diodes of the Wien bridge become shorted...

Hm, I'm starting to think this is not a li-ion battery with a strange form factor but a "li-ion capacitor" or LIC. It's a relatively modern (2010-ish for commercial product) bit of a crossbreed between a lithium battery and a supercap, it should have higher charge/discharge speed than a battery (but lower than an actual cap that can dump everything in a snap) and higher capacity than a capacitor (but much lower than a battery).
