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.
