Abstract
High voltage C/LiCoO2 Li-ion battery was developed,its specific energy was 217.4 Wh/kg.The optimal areal density of cathode was 2.66 mg/cm2 at 6 C discharge in 3.00-4.35 V at 25 ℃.83.4％ of nominal capacity could be obtained at 1 C discharge at-32 ℃.When charging with 1 C to 4.35 V,discharging with 4 C to 3.00 V and cycled for 300 times,the capacity retention rate was 91.3％.In high temperature storage test,battery was held at 75 ℃ in 2 d and expansion didn't appear.The voltage dropped only 0.146 V and internal resistance was risen 0.5 mΩ.After recovery,the capacity recovery rate reached to 87.7％.关键词
