Volta Invents the Electric Battery

Alessandro Volta announced his invention of the voltaic pile in a letter to the Royal Society of London on March 20, 1800, creating the first battery capable of producing steady electric current. Voltaic piles consisted of alternating discs of zinc and copper or silver separated by brine-soaked cloth or cardboard. This invention settled Volta's scientific dispute with Luigi Galvani over 'animal electricity' by providing a reliable source of continuous current. The voltaic pile enabled subsequent developments in chemistry and physics, including water decomposition through electrolysis and discovery of chemical elements, contributing to the emergence of electrochemistry.
