Panasonic Genuine CR-P2 Photo Lithium Battery Retail Pack - Single

Just like a tank of gasoline or a bullet in a gun, a battery has a lot of energy in it. And if that energy is released in a way that we don't want it to be released a fire can occur or even an explosion. Nowadays lithium ion batteries are used in pretty much everything from children's toys to laptop computers, our cell phones, power tools, and even some vehicles. If there was a simple way to describe why a battery would catch fire and explode, um there would be a simple way to prevent it from happening. There's a lot of pieces and processes that go into making the battery work. If any of those processes go wrong there's a chance for energy to be released. And the reason that happens really is because the electrolyte inside of the battery is an organic solvent, and that solvent is flammable. So if the battery can't vent you build up pressure as the electrolyte burns and then it explodes.
