What's on the Horizon for Battery Power?

An electric battery is an energy-storing device consisting of one or more electrochemical cells that converts chemical energy into electrical energy. Batteries and fuel cells work similarly by converting chemical energy into electrical energy. However, batteries require recharging or disposal (a sealed system), whereas fuel cells require re-fuelling. There are a range of battery types, however, Lithium-ion (Li-ion) batteries are the most commercially successful and developed. The technology is used in vehicles and consumer electronics to provide power.
