Voltaic Pile

Definition

The voltaic pile is considered the first true battery, invented by Alessandro Volta in 1800. This revolutionary device generated a steady electric current through a series of alternating discs made from zinc and copper, separated by cardboard soaked in saltwater. The voltaic pile laid the groundwork for modern electrochemistry and battery technology, showcasing the practical use of chemical reactions to produce electricity.
