<P>PROBLEM TO BE SOLVED: To provide an electrolytic solution arranged to impart an excellent high-temperature resistance without causing the swell of a battery or the like, and a nonaqueous electrolytic solution battery. <P>SOLUTION: The electrolytic solution for a nonaqueous electrolytic solution battery includes an organic solvent and a solute. The electrolytic solution comprises, as additive agents: at least one compound selected from a compound group including bis(oxalate)borate; an imide salt having a sulfonic acid ester group expressed by the formula (I), M[R<SP POS="POST">1</SP>OSO<SB POS="POST">2</SB>NSO<SB POS="POST">2</SB>OR<SP POS="POST">2</SP>]<SB POS="POST">n</SB>(I), where R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>are independent of each other and each represent at least one organic group, M is an alkali metal cation or the like, and n is an integer which is the same as the valence of the cation; and at least one compound selected from a second compound group including an imide salt having a phosphoryl group expressed by the formula (II), M[R<SP POS="POST">3</SP>R<SP POS="POST">4</SP>OPNPOR<SP POS="POST">5</SP>R<SP POS="POST">6</SP>]<SB POS="POST">m</SB>(II), where R<SP POS="POST">3</SP>, R<SP POS="POST">4</SP>, R<SP POS="POST">5</SP>and R<SP POS="POST">6</SP>are independent of each other and each represent an organic group, R<SP POS="POST">7</SP>represents at least one organic group, M represents an alkali metal cation or the like, and m is an integer which is the same as the valence of the cation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
