Abstract:
Provided are a nonaqueous electrolytic solution having an electrolyte salt dissolved in a nonaqueous solvent, the nonaqueous electrolytic solution containing from 0.001 to 5% by mass of 1,3-dioxane and further containing from 0.001 to 5% by mass of at least one selected from a specified phosphoric acid ester compound, a specified cyclic sulfonic acid ester compound, and a cyclic acid anhydride containing a side chain having allyl hydrogen; and an energy storage device using the same. This nonaqueous electrolytic solution is capable of improving electrochemical characteristics at high temperatures and further capable of not only improving a capacity retention rate after a high-temperature cycle test but also decreasing a rate of increase of an electrode thickness.
