PROBLEM TO BE SOLVED: To provide nonaqueous electrolyte solution with high flame resistance and a nonaqueous electrolyte solution battery equipped with the nonaqueous electrolyte solution with excellent battery performance and high safety. SOLUTION: The nonaqueous electrolyte solution consists of a nonaqueous solvent containing cyclic phosphagen compound expressed in formula (I):(NPR<SP>1</SP><SB>2</SB>)<SB>n</SB>[in the formula, R<SP>1</SP>denotes a halogen element, an alkoxy group or an aryloxy group, each independently, and n denotes 3 to 4.], and difluorophosphate compound expressed in formula (II) [in the formula, R<SP>2</SP>is either an alkyl group, cycloalkyl group, alkenyl group, alkoxy-substituted alkyl group, or an aryl group] and succinimide compound expressed in formula (III) [in the formula, R<SP>3</SP>denotes an alkyl group, cycloalkyl group, aralkyl group, aryl group, alkoxy group, or an aryloxy group] and supporting salt. The nonaqueous electrolyte solution battery is provided with the nonaqueous electrolyte solution, a cathode and an anode. COPYRIGHT: (C)2007,JPO&INPIT |
