摘　　要：研究了以LiClO_4为电解质盐,采用不同配比的溶剂、添加剂配制成的系列电解液体系,在0℃工况,对采用不同配方电解液电池的放电性能进行了测试,且讨论了几种电解液的交流阻抗图谱。研究发现:加入配比为DME∶PC∶DOL体积比为5∶2∶3电解液的电池,界面阻抗小,稳定性好,容量保持率高。Using LiClO4 as solute, the electrolytes were made with solvents and additives with different ratios. The electrochemical performance of batteries with these electrolytes was tested at 0 ℃, and their EIS were also measured. The test results show that when the volume ratio of electrolyte is DME∶PC∶DOL=5∶2∶3, the battery has low interface resistance, good stability and high maintain capacity.
