Lead-acid battery

In 1859, Planté invented the lead-acid cell, the first rechargeable battery. His early model consisted of a spiral roll of two sheets of pure lead, separated by a linen cloth and immersed in a glass jar of sulfuric acid solution.Dell ''et al.'' (2001) The following year, he presented a nine-cell lead-acid battery to the Academy of Sciences. In 1881, Camille Alphonse Faure would develop a more efficient and reliable model that saw great success in early electric cars. Planté also investigated the differences between

This device was a mechanical predecessor of the modern-day Marx generator.

Death and legacy

He died on 21 May 1889 in the Bellevue part of Meudon, near Paris. In 1989 the Bulgarian Academy of Sciences established the Gaston Planté Medal, which is awarded every few years to scientists who have made significant contributions to the development of lead-acid battery technology.
