ELECTROLYTIC SOLUTION, FOR ELECTRICAL STORAGE DEVICES SUCH AS BATTERIES AND CAPACITORS, CONTAINING SALT WHOSE CATION IS ALKALI METAL, ALKALINE EARTH METAL, OR ALUMINUM, AND ORGANIC SOLVENT HAVING HETEROELEMENT, METHOD FOR PRODUCING SAID ELECTROLYTIC SOLUTION, AND CAPACITOR INCLUDING SAID ELECTROLYTIC SOLUTION

摘要

Provided is an electrolytic solution in which a metal saltand a solvent exist in a new state . The electrolytic solution ofthe present invention is an electrolytic solution containing a saltwhose cation is an alkali metal , an alkaline earth metal , or aluminum,and an organic solvent having a heteroelement . Regarding anintensity of a peak derived from the organic solvent in a vibrationalspectroscopy spectrum of the electrolytic solution, IsIo issatisfied when an intensity of an original peak of the organic solventis represented as Io and an intensity of a peak resulting from shiftingof the original peak is represented as Is .
