Volta's 'Crown of Cups' battery. Historical illustration of a version of the 'Crown of Cups' battery described in 1800 by Italian physicist Alessandro Volta (1745-1827). This device consists of a series of containers (cells) holding brine and electrodes consisting of plates of zinc (Z) and copper (C, sometimes silver). Metal hoops (A) connect the cells in a series. When the ends are connected (centre), electricity flows. The 'pile' version of his battery is a stack of alternating discs of zinc and copper immersed in an electrolyte. Artwork from 'Electricite' (1911) by Max de Nansouty, part of the 'Les merveilles de la science' series of 1867-1891 by Louis Figuier.
