Voltaic pile

1800

The voltaic pile was the first electrical battery that could provide a continuous current. It was invented by the Italian physicist Alessandro Volta and consisted of a stack of alternating zinc and copper discs separated by cloth or cardboard soaked in brine or acid. Volta announced it in a letter to the Royal Society of London. It grew out of his debate with Luigi Galvani over animal electricity, the twitching of frogs' legs, in which Volta argued that the electricity came from the contact between different metals and not from the animal tissue. The pile led to rapid advances: the electrolysis of water, Humphry Davy's discovery of new elements such as sodium and potassium, and later the study of electromagnetism. The unit of electric potential, the volt, is named after Volta.
