    摘要： To provide an ionic liquid which has at least one of properties such as high ionic conductivity, a small reduction in ionic conductivity at a low temperature, a low melting point, and a low viscosity. To provide a power storage device having higher initial charge and discharge efficiency than a power storage device containing a conventional ionic liquid. A cyclic quaternary ammonium salt is liquid at room temperature and contains a quaternary spiro ammonium cation having an asymmetrical structure including two aliphatic rings and one or more substituents bonded to one or both of the two aliphatic rings and an anion corresponding to the quaternary spiro ammonium cation. The power storage device includes a positive electrode, a negative electrode, and a nonaqueous electrolyte containing the cyclic quaternary ammonium salt as a nonaqueous solvent.

    摘要： When cellulose is used as a separator, the cellulose is impregnated with an ionic liquid. Charge and discharge are repeated with this separator touching a surface of a current collector; then, the separator is changed in color. Thus, it is an object to provide a power storage device with a structure in which a side reaction other than a battery reaction, e.g., a change in color of separator, is unlikely to occur. In the power storage device, a separator impregnated with an ionic liquid is not in contact with a surface of a current collector. The separator has a tubular shape, a bag-like shape, or a sheet-like shape. The separator includes cellulose. The power storage device including the ionic liquid is non-volatile and non-flammable. The power storage device can be bent.

    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.
