摘要

本文研究了用于锂电池的LiPF6_乙烯碳酸酯(EC)_甲基乙酸酯(MA)电解液体系,测定了该体系在不同的溶剂配比和盐浓度下于20℃~-50℃时的电导率,给出该体系性能最佳的溶剂配比和盐浓度,以此进行循环伏安和充放电测试,并与商用电解液(LiPF6 EC 二乙基碳酸酯(DEC)进行了比较.

Abstract

The system of LiPF6_ethylene carbonate (EC) _methy1 acetate (MA) was studied. The conductivities of this system were measured under various composition and various salt concentrations at temperature range of 20~-50 ℃. The optimum composition of this system was selected. The tests of cyclic voltammography and charge_discharge were carried out. This system was compared with commercial electrolyte solution.
