Wollaston battery pile. Historical illustration of the battery designed in the 1810s by British chemist William Hyde Wollaston (1766-1828). This design consists of seven plates immersed in an acid in glass containers. The plates are a U-shaped piece of copper, with a plate of zinc inside (cork prevents the metals touching). Wires at the terminals (left and right) allow connection to supply power to a circuit. Wollaston's design allowed the zinc-copper plates in the battery to be raised out of the acid, making it last longer. Artwork from 'Electricite' (1911) by Max de Nansouty, part of the 'Les merveilles de la science' series of 1867-1891 by Louis Figuier.
