The first battery was created by Alessandro Volta in 1800. It was prompted by the discovery of “animal electricity” which Luigi Galvani made when he placed two different metals in a frog leg and noticed the leg twitched. As Alessandro Volta believed that the leg contraction was due to the metals and not the animal nature, he proved such by creating the first battery: a column of alternating disks of Zinc (anode) and copper (cathode) separated by a cloth soaked in brine (the electrolyte). This battery was called the Voltaic pile.
