Early electric battery. Historical artwork of a voltaic pile,the first modern type of electric battery,which was invented in 1800 by the Italian physicist Alessandro Volta (1745-1827). A voltaic pile consists of alternating units (one shown at right) of plates of two different metals and a piece of wet cardboard or cloth. Here,from top to bottom,the unit is: copper plate,wet cardboard,zinc plate. A pile of these units makes up the voltaic pile in the main picture. Wires at top and bottom carry the electric current,produced by a chemical reaction,to power an electrical device. Zinc and copper are still used in batteries today.
