电解液对圆柱形Li/MnO2电池性能的影响

摘要

Cylindrical Li/MnO2 batteries were assembled using LiC1O4 electrolyte, LiPF6 electrolyte and a mixture of these two electrolytes to analyses the effect of LiPF6 to the performance of battery. Through the introducing of LiPF6 led the rising of open circuit voltage and decreasing of capacity, but the largest reduce of peak temperature was 137 ℃ during over-discharge. That was beneficial to improve the safety performance of the battery.%使用LiClO4电解液、LiPF6电解液及两者的混合电解液装配圆柱形Li/MnO2电池,分析LiPF6对电池性能的影响.引入LiPF6后,虽然开路电压上升,放电容量下降；但过放电时的峰值温度最高下降137℃,有利于提高电池的安全性能.
