The present invention provides a non-aqueous electrolytic solution and an electrical storage device using the non-aqueous electrolytic solution. The non-aqueous electrolytic solution is a non-aqueous electrolytic solution in which an electrolyte salt is dissolved in a non-aqueous solvent. Contains 0.001 to 5% by mass of 1,3-dioxane, and further contains 0.001 to 5% by mass of a specific phosphoric acid ester compound, a specific cyclic sulfonate compound, and a side containing allyl hydrogen At least one of chained cyclic anhydrides. The non-aqueous electrolytic solution can improve the electrochemical characteristics at high temperature, thereby not only reducing the capacity retention rate after a high-temperature cycle test, but also reducing the increase rate of electrode thickness. |
