Actually a bomb is something that is programmed to detonate intentionally under certain conditions. There are plenty of other similarly energetic chemicals around the house, like gas in cylinders. The problem with some batteries is, unlike a bomb, the detonation conditions are hard to control. Luckily battery ignition, as enegetic as it is, is low velocity.
