摘要
Abstract
The cycle performance of lithium iron phosphate (LiFePO4) cathode Li-ion battery was studied. When the battery cycled with 1 C,100% depth of discharge (DOD),the cycle number under normal temperature was more than 1 800 times,it was only about 200 times under 60 ℃ high temperature. The growth of internal resistance and thickness of the battery under high temperature was bigger than under normal temperature, which indicated that the capacity decay was accelerated by high temperature. The capacity under normal temperature increased about 9.46% after injecting electrolyte into the battery which suffered at high temperature cycle. The lack of electrolyte was one of the reasons that caused the decay of cycle performance of battery under high temperature,but it wasn't the primary reason.关键词
