Battery is any device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy. Batteries are made from many materials including various metals, carbon, polymers and even air. The most common are lead-acid batteries used in vehicles and lithium ion batteries used for portable electronics. Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to battery banks the size of rooms that provide standby power for telephone exchanges and computer data centers.
Batteries have recently received significant research and development, because they are hoped to provide a solution for energy storage in a transition from fossil fuels to alternative energy, both for transport and electricity production and for powering portable devices of all kinds.
