    Abstract: One object is to provide a power storage device including an electrolyte using a room-temperature ionic liquid which includes a univalent anion and a cyclic quaternary ammonium cation having excellent reduction resistance. Another object is to provide a high-performance power storage device. A room-temperature ionic liquid which includes a cyclic quaternary ammonium cation represented by a general formula (G1) below is used for an electrolyte of a power storage device. In the general formula (G1), one or two of R1 to R5 are any of an alkyl group having 1 to 20 carbon atoms, a methoxy group, a methoxymethyl group, and a methoxyethyl group. The other three or four of R1 to R5 are hydrogen atoms. A− is a univalent imide anion, a univalent methide anion, a perfluoroalkyl sulfonic acid anion, tetrafluoroborate (BF4−), or hexafluorophosphate (PF6−).

    Abstract: 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.
