A Battery is a chemical device that stores electrical energy in the form of chemicals and by means of electrochemical reaction, it converts the stored chemical energy into direct current (DC) electric energy. Alessandro Volta, an Italian Physicist, invented the first battery in 1800.
The electrochemical reaction in a battery involves transfer of electrons from one material to another (called electrodes) through an electric current.
