The lithium-ion batteries were first conceptualized by Prof. Wittingham 1970s with the discovery of Li-TiS2 but the very low potential generated resulted in limiting its energy density and subsequently its practical applications. Lithium-ion batteries were commercialized due to the discovery of cathode chemistries like Lithium cobalt oxide (LiCoO2) , Lithium manganese oxide (LiMn2O4) and Lithium iron phosphate (LiFePO4) by Professor Goodenough in the 1980s and 1990s.
