CAPACITOR INCLUDING ELECTROLYTE CONTAINING SALT USING ALKALI METAL, ALKALI-EARTH METAL OR ALUMINUM AS CATIONS, AND ORGANIC SOLVENT HAVING HETERO ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a capacitor including an electrolyte where a metal salt and a solvent are present in a new condition.SOLUTION: A capacitor comprises an electrolyte which contains a salt using alkali metal, alkali-earth metal or aluminum as cations, and an organic solvent having a hetero element. Related to peak intensity originally coming from the organic solvent in vibrational spectra of the electrolyte, when intensity of a peak of the original organic solvent is "Io", and intensity of a peak where the peak shifts is "Is", the relation: IsIo is satisfied.SELECTED DRAWING: None
