Alessandro Giuseppe Antonio Anastasio Volta (UK: / ˈ v ɒ l t ə /, US: / ˈ v oʊ l t ə /; Italian: [alesˈsandro ˈvɔlta]; 18 February 1745 – 5 March 1827) was an Italian physicist and chemist who was a pioneer of electricity and power, [1] [2] [3] and is credited as the inventor of the electric battery and the discoverer of methane.
A voltaic pile on display in the Tempio Voltiano (the Volta Temple) near Volta's home in Como, Italy Voltaic pile, University History Museum of the University of Pavia. The voltaic pile was the first electrical battery that could continuously provide an electric current to a circuit. [ 1 ]
In 1800, Volta invented the first true battery, storing and releasing a charge through a chemical reaction instead of physically, which came to be known as the voltaic pile. The voltaic pile consisted of pairs of copper and zinc discs piled on top of each other, separated by a layer of cloth or cardboard soaked in brine (i.e., the electrolyte ).
Italian physicist Alessandro Volta built and described the first electrochemical battery, the voltaic pile, in 1800. [6] This was a stack of copper and zinc plates, separated by brine-soaked paper disks, that could produce a steady current for a considerable length of time. Volta did not understand that the voltage was due to chemical reactions.
A year after Galvani published his work (1790), Alessandro Volta showed that the frog was not necessary, using instead a force-based detector and brine-soaked paper (as electrolyte). (Earlier Volta had established the law of capacitance C = Q / V with force-based detectors). In 1799 Volta invented the voltaic pile, which is a stack of ...
Alessandro Volta demonstrates his battery to Napoleon. Alessandro Volta, a contemporary physicist, believed that the effect was explicable not by any vital force but rather it was the presence of two different metals that was generating the electricity. Volta demonstrated his theory by creating the first chemical electric battery. [9]

A silver oxide cell was first constructed by Alessandro Volta in late 1800. [4] This consisted of a circle of cups of a liquid saline electrolyte, containing alternating zinc and silver strips connected by wire. It is claimed that 20 such cups were sufficient for the hydrolysis of water. [5]
