摘要 以富锂锰基材料、人造石墨分别为正、负极活性材料,通过优化化成流程、充放电截止电压、负极/正极容量比(N/P)和电解液添加剂等参数,研制电动汽车用动力锂离子电池.N/P为1.37,采用氟代碳酸乙烯酯体系电解液,分别添加1%的正、负极成膜添加剂和HF酸捕捉添加剂,通过4.6V高压活化,以0.5C在2.00~4.35 V充放电,富锂锰基材料电池的放电比容量为179.8 mAh/g,首次循环的库仑效率为87%,比能量为187 Wh/kg,室温循环800次的容量保持率为80%. Based on lithium-riched manganese based material and artificial graphite as positive and negative active material, respec- tively, power Li-ion battery for electric vehicle was developed by optimizing parameters such as formation process, charge-discharge end voltage, capacity ratio of negative/positive(N/P) and electrolyte additive. When the N/P was 1.37, using fluorethylene carbo- nate(FEC) system electrolyte and adding 1% of cathode ,anode film forming additive,HF acid capture additive ,through 4. 6 V high voltage activation,when charged-discharged in 2. 00 - 4. 35 V with O. 5 C, the specific discharge capacity of battery with lithium- riched manganese based material was 179. 8 mAh/g, the Coulombic efficiency in initial cycle was 87% , the specific energy was 187 Wh/kg, the capacity retention ratio was 80% when cycled 800 times at room temperature.
