Abstract
The overcharge characteristics and effect factors of lithium-ion cells containing LiMn_(2)O_(4)cathodes were studied in detail.Overcharge testing of Lithium-ion cells with a systematic variation in the cell balance demonstrated that the overcharge characteristics of Lithium-ion cells was affected by the amount of cathode in the cells,which is independent of the amount of anode material.The rate of charge was found to be an important parameter,as electrolyte complete decomposition at low charge rates caused the end of overcharge testing,while high charge rates accelerated the rate of heat generation in the cells and the cell temperature increased as a result of insufficient heat dissipation.The cell temperature rise led to the separator shut down and testing end.
