摘要： An object of the present invention is to provide a nonaqueous electrolytic solution and a nonaqueous electrolytic solution battery capable of showing high output characteristics at a low temperature even after the battery is used to some extent, and capable of showing good high-rate properties, and further capable of showing sufficient performance again at low temperature even after stored at a high temperature. The present invention is characterized in the use of a nonaqueous electrolytic solution containing a nonaqueous organic solvent and an electrolyte dissolved in the nonaqueous organic solvent, the nonaqueous electrolytic solution comprising a difluoro ionic complex (1-Cis) in a cis configuration represented by the general formula (1-Cis), and at least one compound selected from the group consisting of a carbonate having an unsaturated bond, a carbonate having a fluorine atom, an acid anhydride, and a compound having an isocyanato group.
