Abstract:
The electrolyte solution for a lithium ion secondary battery according to the present invention contains a nonaqueous solvent, a lithium salt and a compound represented by the general formula (Z) shown below. Thereby, a lithium ion secondary battery having high battery characteristics and simultaneously achieving a high safety as well can be provided. R—SO2—Ar1—O—R1 (Z) wherein Ar1 denotes a substituted or nonsubstituted divalent aromatic group having 5 to 30 atoms of the nucleus(es); R1 denotes a saturated or unsaturated monovalent hydrocarbon group having 1 to 20 carbon atoms; and R denotes a saturated or unsaturated monovalent hydrocarbon group having a perfluoroalkyl group and having 2 to 22 carbon atoms.
