A battery is an electrochemical device that converts stored chemical energy into electrical energy. Batteries are made up of one or more cells, each of which consists of an anode, a cathode, and an electrolyte. When a battery is supplying power, electrons flow from the anode to the cathode through the electrolyte.

Batteries are used in a wide variety of applications, including portable devices, electric vehicles, and grid-scale storage. The most common type of battery is the lead-acid battery, which is used in automobiles and other vehicles. Other common types of batteries include nickel-cadmium, nickel-metal-hydride, and lithium-ion.
