History of the battery his iron scalpel, the leg twitched. Galvani believed the energy that drove this contraction came from the leg itself, and called it "animal electricity". However, Alessandro Volta, a friend and fellow scientist, disagreed, believing this phenomenon was caused by two different metals joined together by a moist intermediary. He verified this hypothesis through experiment, and published the results in 1791. In 1800, Volta invented the first true battery, which came to be known as the voltaic pile. The voltaic pile consisted of pairs of copper and zinc discs piled on top of each other, separated by a layer of cloth
Battery electric vehicle Vehicles. In the European Union, on average, between 2009 and 2013 there was a reduction of the electricity Carbon Intensity of 17%. In a Life-cycle assessment perspective, considering the GHG necessary to build the battery and its end-of-life, the GHG savings are 10-13% lower. Although electric cars do not produce any tailpipe emissions, carbon dioxide is still emitted when the electric vehicle is being manufactured. The lithium-ion batteries used in the vehicle take more materials and energy to produce because of the extraction process of the lithium and cobalt essential to the battery. This means the bigger the electric vehicle,
