Abstract

The present invention provides a nonaqueous electrolytic solution capable of improving electrochemical characteristics in a broad temperature range and an energy storage device using the same. [1] A nonaqueous electrolytic solution having an electrolyte salt dissolved in a nonaqueous solvent, the nonaqueous electrolytic solution containing, as an additive, an SOgroup-containing compound having a specified structure and [2] an energy storage device including a positive electrode, a negative electrode, and a nonaqueous electrolytic solution having an electrolyte salt dissolved in a nonaqueous solvent, wherein the nonaqueous electrolytic solution contains, as an additive, 0.001% by mass or more and less than 5% by mass of an SOgroup-containing compound having a specified structure in the nonaqueous electrolytic solution, are disclosed.
