Abstract

See full text

The demand for improvements in lithium non-aqueous electrolyte secondary batteries has been constantly increasing in recent years, but the durability—most prominently the cycle characteristics—have resided in a trade off relationship with properties such as the capacity, resistance, and output characteristics. A problem has thus been a poor overall property balance. In order to solve this problem, the present invention uses a non-aqueous electrolyte solution including, in addition to an electrolyte and a non-aqueous solvent, (A) at least one compound selected from the group consisting of carbonates having a carbon-carbon unsaturated bond, compounds represented by the following general formula (1), sulfoxides, sulfites, sulfones, sulfonates, sultones, and sulfates; (B) a fluorine atom-containing cyclic carbonate; and (C) a compound that has at least two isocyanate groups in the molecule.
