If 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. Flamethrower

If 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.
