"And if you think you can store more energy in a solid battery without turning it into explosive you're out of luck, next step up from lithium in energy density is a gunpowder"
I had a minor LiPo 'scare' the other day when I was doing some battery capacity/behavior testing on a device. I soldered up what SHOULD have been a simple current monitoring 'thing' that went between the battery and device, so I could do long-term measurements with a microcontoller. Unfortunately, even under the magnifier, I couldn't see a tiny solder finger that shorted out the LiPo battery. Within 10 seconds it swelled up like a balloon and started melting the vinyl covering on the table it sat on. I rapidly disconnected it, and when the swelling didn't go back down, I quickly ran with it to a nearby sink and doused it with water (and within a few seconds, it suddenly collapsed to being 'flat' again) until it was 'cool to the touch'.
Unfortunately the battery couldn't be charged any more (must've melted inside). I really didn't need the thing blowing up in my face, so I'm glad it stayed "contained". THAT was only a 400maH battery. I can't imagine what the battery of a vehicle would be like, if something shorted it out [like a traffic accident?]
icon, because, that's almost what happened. having a fire extinguisher handy is helpful, but I'd rather not use it. Having a shower nearby to wash the burning lithium off won't be that much help, either.
just putting it into perspective...
/me points out, safe LiPo disposal: cut battery in half with scissors, drop into plastic cup with water in it. When bubbles stop, you can rinse the lithium out and toss the rest in the garbage. at least, that's what I'm inclined to do...
