The Voltaic Pile is considered the first true battery, invented by Italian scientist Alessandro Volta in 1800. It consists of alternating discs of zinc and copper, separated by layers of cardboard soaked in saltwater. This arrangement creates a chemical reaction that generates a steady flow of electric current. The invention of the Voltaic Pile marked a significant advancement in the study of electricity. It provided a reliable source of electrical energy for experiments and laid the groundwork for future developments in electrochemistry and battery technology.
