ABSTRACT:
The present invention provides an electrolyte for use in a secondary lithium battery comprising (i) vanadium oxide-based cathode active material having a molar ratio of oxygen to vanadium between two and three, (ii) an anode active material selected from the group consisting of lithium, lithium ion dischargeable alloys, lithium ion dischargeable intercalation or insertion compounds, and (iii) an electrolyte solution of lithium salt(s) dissolved in a mixed organic solvent. The organic solvent is a mixture of three kinds of solvents, namely ethylene carbonate (EC), propylene carbonate (PC) and 2-methyltetrahydrofuran (2MeTHF) in the following ratio:
