NONAQUEOUS ELECTROLYTE SOLUTION, AND NONAQUEOUS ELECTROLYTE BATTERY

A nonaqueous electrolytic solution contains a salt compound represented by a specific general formula, a solute, and a nonaqueous organic solvent, in which the content of the salt compound with respect to the total amount of the nonaqueous electrolytic solution is 0.003% by mass to 0.1% by mass, and a nonaqueous electrolytic solution battery contains the nonaqueous electrolytic solution, so that there is provided a nonaqueous electrolytic solution that can exhibit an effect of improving a capacity retention rate after a long-term cycle at a high temperature and an effect of preventing an increase in resistance at a low temperature after high-temperature storage in a balanced manner, and a nonaqueous electrolytic solution battery containing the nonaqueous electrolytic solution.
