The Voltaic pile was the first modern electric Battery , invented by Alessandro Volta in 1800 . Volta demonstrated that when Metal s and Chemical s come into contact with each other they produced an Electric al current. In his research, Volta placed together several pairs of alternating Copper (or Silver ) and Zinc discs separated by cloth and soaked the cloth 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. William Nicholson and Anthony Carlisle discovered Electrolysis of water using the Voltaic pile. Humphry Davy showed that electricity from Voltaic piles was caused by a chemical reaction (not by differentials between metals as previously believed). William Hyde Wollaston showed that electricity from Voltaic piles was identical to electricity produced by Friction . Davy also used the Voltaic pile to decompose and discover materials. Contact Tension was an early theory that attempted to explain the action of the voltaic pile; it is now an Obsolete Scientific Theory and has been replaced by the current theories of Electrochemistry .
