LTO cells can also be re-operated after an event of an over-discharge, unlike conventional graphite based Li-Ion cells. This feature enables the user to operate the battery cells under extreme environmental and operational conditions. Conventional Li-ion batteries use a graphite anode whereas LTO cell use titaniumbased compound. Kokam's specialized technology maximizes the performance of cells.
