When something keeps ending up in the headlines on a regular basis, I like to learn a little bit more about it. Lithium-Ion batteries are one of those things. They are great for powering devices of all kinds. I have one in my pocket in a flashlight, one in my phone, another in a keychain flashlight. You get the idea. Unfortunately, when things go wrong with them, they can make quite a mess. The eggheads at Wired took an in-depth look at the power storing pyrotechnics and have some information here that you may find interesting.
