NONAQUEOUS ELECTROLYTIC SOLUTION AND NONAQUEOUS ELECTROLYTIC SOLUTION BATTERY INCLUDING NONAQUEOUS ELECTROLYTIC SOLUTION

The present invention relates to a nonaqueous electrolytic solution comprising an electrolyte, a nonaqueous solvent, a compound represented by general formula (I), and at least one specific anion-containing compound selected from an anion-containing compound having a P═O bond and a P—F bond, an anion-containing compound having an S═O bond and an S—F bond, and an alkyl sulfate anion-containing compound, in which the mass ratio of the compound represented by the general formula (I) to the specific anion-containing compound satisfies a specific range. The present invention also relates to a nonaqueous electrolytic solution battery comprising a negative electrode and a positive electrode capable of occluding and releasing metal ions, and the nonaqueous electrolytic solution.
