17. The First Battery Alessandro Volta (1745 – 1827) Generate electricity by putting a layer of cardboard soaked in brine between discs of copper and zinc – a voltaic cell. When he made a ‘pile’ of these cells, he increased the amount of electricity generated. This was the first battery – a collection of cells. Newmark, CHEMISTRY,  1993, page 46 Zinc disc Copper disc
