OverviewHistoryDesignFormatsUsesPerformanceLifespanSafety

Research on rechargeable Li-ion batteries dates to the 1960s; one of the earliest examples is a CuF 2/Li battery developed by NASA in 1965. The breakthrough that produced the earliest form of the modern Li-ion battery was made by British chemist M. Stanley Whittingham in 1974, who first used titanium disulfide (TiS 2) as a cathode material, which has a layered structure that can take in lithium ions without significant changes to its crystal structure. Exxon tried to commercialize this ba…
