    摘要： A nonaqueous electrolyte of the present invention includes an ionic liquid including a first alicyclic quaternary ammonium cation having one or more substituents, a second alicyclic quaternary ammonium cation having an alicyclic skeleton that is the same as an alicyclic skeleton of the first alicyclic quaternary ammonium cation, and a counter anion to the first alicyclic quaternary ammonium cation and the second alicyclic quaternary ammonium cation and an alkali metal salt. In the second alicyclic quaternary ammonium cation, one of substituents bonded to a nitrogen atom in the alicyclic skeleton is a substituent including a halogen element. In the ionic liquid, the amount of a salt including the second alicyclic quaternary ammonium cation is less than or equal to 1 wt % per unit weight of the ionic liquid, or is less than or equal to 0.8 wt % per unit weight of the nonaqueous electrolyte.

    摘要： A power storage device using an organic solvent as a nonaqueous solvent for a nonaqueous electrolyte, in which a CV charging period in CCCV charging can be prevented from being extended and which has high performance, can be provided. The power storage device includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. The nonaqueous electrolyte includes an ionic liquid including an alicyclic quaternary ammonium cation having one or more substituents and a counter anion to the alicyclic quaternary ammonium cation, a cyclic ester, and an alkali metal salt. In particular, in the power storage device, the ionic liquid content is greater than or equal to 70 wt % and less than 100 wt % per unit weight of the ionic liquid and the cyclic ester in the nonaqueous electrolyte, or greater than or equal to 50 wt % and less than 80 wt % per unit weight of the nonaqueous electrolyte.
