electrolyte solution, for electrical storage devices such as batteries and capacitors, containing salts whose cation is an alkali metal, alkaline earth metal, or aluminum, and organic solvent having heteroelement, method for producing said electrolyte solution, and capacitor including said electrolyte solution

摘要

an electrolyte solution in which a metal salt and a solvent are present in new states. An electrolyte solution according to the present invention contains a salt, wherein alkali metal, an alkaline earth metal, or aluminum, function as cations, and an organic solvent having a heteroelement. This electrolyte solution is characterized by the fact that with respect to an intensity of a peak assigned to the organic solvent in a vibrational spectrum of the electrolyte solution, if io is the original peak intensity of the organic solvent and is is the intensity of a peak of change. of the organic solvent, i and i satisfy is io.
