Abstract:
The present invention aims to provide an electrolyte solution containing a quaternary ammonium salt as an electrolyte salt and is capable of providing an electrochemical device having a high capacitance retention and reducing generation of gas. The electrolyte solution of the present invention contains a solvent, a quaternary ammonium salt, and a nitrogen-containing unsaturated cyclic compound. The unsaturated cyclic compound is a nitrogen-containing unsaturated heterocyclic compound. The unsaturated cyclic compound excludes salts of the unsaturated cyclic compound and ionic liquids obtainable from the unsaturated cyclic compound.
Abstract:
Provided is an electrolyte salt comprising a quaternary ammonium cation indicated by formula (1) and a trimethylsilyl alkanesulfonate anion indicated by formula (2). (In the formula, R 1 -R 4 each independently indicate a C1-4 alkyl group or an alkoxyalkyl group indicated by -(CH 2 ) n -OR. Any two among R 1 -R 4 can mutually bond and form a ring together with a nitrogen atom to which same have bonded. The remaining two can mutually bond and form a spiro ring having a nitrogen atom as the spiro atom therefor. R indicates a methyl group or an ethyl group. n indicates 1 or 2 and m indicates 2 or 3.)
