What was Alessandro Volta's battery called?

Alessandro Volta's invention, known as the Voltaic pile, is recognized as one of the first true batteries that could provide a continuous source of electrical current. The Voltaic pile was constructed from alternating discs of zinc and copper, separated by layers of cardboard soaked in saltwater or acid, which served as an electrolyte. This arrangement created a chemical reaction that released electrons, generating an electric potential difference between the two different metals, resulting in a flow of electricity.

The significance of the Voltaic pile lies in its ability to produce a steady electrical current, which laid the foundational principles for future advancements in electrochemistry and battery technology. It represented a pivotal moment in the history of electricity as it demonstrated that chemical reactions could be harnessed to generate electrical energy.
