摘要 |
A non-aqueous secondary electrochemical battery (1) which comprises a complex oxide containing lithium for a cathode (6), a carbon material for an anode (4), and a mixed solvent for an electrolyte is disclosed. The mixed solvent is obtained by dissolving an inorganic salt in a mixture of a cyclic ester and a chain ester. The cyclic ester is selected from the group consisting of ethylene carbonate, propylene carbonate, butylene carbonate, and gamma -butyrolactone. The chain ester is selected from the group consisting of diethyl carbonate, dimethyl carbonate, ethyl formate, methyl formate, ethyl acetate, methyl acetate, and dimethyl sulfoxide. In this way, a non-aqueous secondary electrochemical battery having improved cycle life capabilities, discharge performance, and low temperature performance can be obtained. <IMAGE> |
