摘　　要：研究了极片面密度、隔膜厚度以及电解液等因素对锂离子电池高倍率放电性能的影响.通过实验优化制备的实验电池以20 C大电流放电电压平稳,20 C循环100次,容量保持率为93%以上.电池具有较好的倍率性能和循环性能.The influence factors of the high rate discharge performance of Li - ion battery were studied. With the factors optimized combination, a Li - ion battery was developed with discharge fiat voltage platform at 20 C rate, and the 20 C discharge capacity retained 90% of the initial discharge capacity after 100 cycles. The rate discharge performance and cycle performance were fine.
