| Abstract: | 10 Ah LiFePO4 Li-ion power battery was prepared by using LiFePO4 and MCMB as positive and negative active materilas.Functional electrolyte was used in 10 Ah LiFePO4 Li-ion power battery.The battery performance between the incorporate cap and freestanding cap used in the battery were researched respectively.For the battery used incorporate cap,its average internal resistance was 2.0 mΩ,its maximal discharge rate and maximal charge rate were 10 C and 5 C,respectively,and its 5 C cycle capacity retained 86.4% after 600 cycles.For the battery used freestanding cap,its average internal resistance was 3.4 mΩ,its maximal discharge rate and maximal charge rate were 5 C and 3 C,respectively,and its 1 C cycle capacity retained 87.4% after 600 cycles. |
