Abstract
The performance of 2 ％ state-of-charge (SOC) (the remained capacity was 0.1 Ah) for graphite/lithium iron phosphate (LiFePO4) Li-ion battery after stored for 6 h under different temperatures (25 ℃,50 ℃,60 ℃ and 70 ℃) was studied.The normal/high temperature charge retention ability,low temperature(-20 ℃) discharge and normal temperature 1 C cycle(2.50-3.65 V) performance were tested.The normal/high temperature charge retention ability and low temperature (-20 ℃) discharge performance of the batteries increased firstly and then decreased with the increasing of store temperature,when the store temperature was 60 ℃,the optimal value of performance mentioned above was achieved.The discharge capacity retained round 88 ％ for the stored temperature above 50 ℃ of rated capacity after 1 500 cycles at 1 C.关键词
