I've never opened a lithium cell that has an internal short circuit before, so I thought it would be quite interesting to do. It was also a good opportunity to see how they jam so much chemistry into the standard 18650 package. If this is how stuffed a 2200mAh cell is then it shows why the 3000mAh cells are so expensive. There must be a lot of work in jamming even more chemistry in, and it shows how safety could be compromised by pushing everything to the edge to make it fit.
The other video where I discuss the rechargeability of over-discharged cells is here:-

If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
