Non-aqueous electrolyte solution and non-aqueous electrolyte solution secondary battery using it
Document Type and Number:
Japanese Patent JP6361518
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide: a nonaqueous electrolytic solution which enables the improvement of both of initial battery characteristics and post-endurance test battery characteristics; and a nonaqueous electrolytic solution secondary battery using such a nonaqueous electrolytic solution.SOLUTION: A nonaqueous electrolytic solution for secondary batteries comprises: an electrolyte; a nonaqueous solvent; an aromatic carboxylic acid ester given by the formula (1); and at least one compound selected from a fluorine-containing cyclic carbonate, a sulfur-containing organic compound, phosphonate, an organic compound having a cyano group, an organic compound having an isocyanate group, a silicon-containing compound, an aromatic compound other than the aromatic carboxylic acid ester, a particular carboxylic acid ester, a cyclic compound having more than one ether linkage, a monofluorophosphate, a difluorophosphate, a borate, an oxalate, and a fluorosulfonate. [formula (1)] (Arepresents an aryl group; nand aare an integer of one or two; when ais one, Ris an aryl group or the like, whereas when ais two, Ris an arylene group or the like.)
