Entry Twenty: What's That in your iPod?

This weekend, I listened a lot to my iPod, which happens to be powered by a lithium-ion battery. This is a battery that uses the chemical reactions of lithium and carbon to produce energy, and it can store about 150 Wh of energy. The iPod is powered by a pack of these batteries, so it can play for several hours before it needs a recharge. This is great for listening to the Power Rangers Theme song over and over again, and also great for listening to anything else. The thing is, these batteries have the problem of occasionally bursting into flame, which is scary.
