Abstract:LiFePO_4 and LiMn_2O_4 was mixed with the mass ratio of 78:9 and used as cathode material of Li-ion battery. The pro-per charge-discharge voltage range of 14500 type battery using the mixed cathode was 4.20~2.50 V. When 1.0 C cycle at room temperature,the capacity retention rate was 87.47% after 250 cycles,when 1.0 C cycle at 60 ℃,the capacity retention rate was 84.62% after 12 cycles. When the battery was stored 7 d at 60 ℃ with 100% SOC,the capacity retention rate was 82.50%,the capacity recovery rate was 89.01%.
Keywords:LiFePO_4  LiMn_2O_4  Li-ion battery  cathode material  mixed cathode  LiFePO_4  LiMn_2O_4
