ENPOLITE: Comparing Lithium-Ion Cells across Energy ...
Research in lithium batteries began in 1912 under G.N. Lewis, but the breakthrough came in 1958 when Harris noticed the stability of Li-metal in a number of nonaqueous (aprotic) electrolytes such as fused salts, liquid SO 2, or lithium salt into an organic solvent such as LiClO 4 in propylene carbonate (C 4 H 6 O 3).
