voltaic pile

The Voltaic pile is the first modern electric battery, invented by Alessandro Volta in 1800. Volta demonstrated that when metals and chemicals come into contact with each other they produced an electrical current. In his research, Volta placed together several pairs of alternating copper (or silver) and zinc discs separated by cloth or cardboard and soaked the cloth or cardboard in brine (salt water) to increase conductivity, and an electrical current was produced. On March 20, 1800, Volta wrote to the London Royal Society to describe the technique for producing electrical current using his pile.
