A battery is ultimately a chemical separation of charge. The battery consists of two metal plates placed in a salt solution: one metal produces excess negative charges when reacting with the salt solution (leaving the metal negative) and one metal produces negative charge in the salt solution leaving the metal positive. Chemically this is often referred to as a [[https:// | A battery is ultimately a chemical separation of charge.
