摘要:
Provided is an electrolytic solution in which a metal salt and a solvent exist in a new state. The electrolytic solution of the present invention is an electrolytic solution containing a salt whose cation is an alkali metal, an alkaline earth metal, or aluminum, and an organic solvent having a heteroelement. Regarding an intensity of a peak derived from the organic solvent in a vibrational spectroscopy spectrum of the electrolytic solution, Is>Io is satisfied when an intensity of an original peak of the organic solvent is represented as Io and an intensity of a peak resulting from shifting of the original peak is represented as Is.
