No, not particularly- the energy stored in an li ion cell is only a small amount of its potential energy. The cathode (eg cobalt oxide) and the organic electrolyte act as an oxidizer and fuel, >10x more energetic than the energy stored in the lithium.
Solid state batteries carry far less energy than a normal battery.
- api 8y agoHow could that be the case if they hold more energy or are more dense? It's just physics. I wasn't saying they couldn't work, just that if they did fail they'd have the potential to fail spectacularly. Same is true for a gasoline tank.
- hwillis 8y agoIf solid state cells had 3x more energy per volume, they'd have slightly less energy to release than a normal li ion cell, and those aren't bombs. Flamethrowers at worst. A bomb requires way more than just energy, it needs to have a mechanism to release quickly. Li ion has a mechanism like that, but solid state batteries don't.
