摘要
研究了不同阴极导电剂含量对锂离子蓄电池的充放电性能和阻抗性能的影响。对锂离子蓄电池交流阻抗谱测定表明,聚合物锂离子蓄电池阴极在充放电循环过程中,其电化学反应阻抗的变化值与电极中导电剂含量有一定的相关性,根据这一相关性得到一种新的确定锂离子蓄电池阴极中导电剂最佳含量的方法。
The influence of cathode conductive agent content to battery performance and AC impedance were investigated. The determination result of AC impedance spectrum of polymer lithium ion battery shows that the variation value of cathode charge transfer impedance is relative to the conductive agent content in this cathode. A new method of calibration of optimal cathode conductive agent content is presented according to this relativity.
