How batteries will change the world.
Introduction
Batteries are the future. They're used in everything from cell phones to cars, but they also have applications far beyond those uses. Batteries can store energy over long periods of time, which makes them great for storing electricity for later use or charging devices when there's not enough sunlight available. That same ability to store energy also means batteries could replace oil as a fuel source--and even eliminate solar panels altogether!
