PROBLEM TO BE SOLVED: To provide an electrolyte arranged to use a quaternary ammonium salt as an electrolyte salt, which enables the materialization of an electrochemical device high in capacity-keeping rate and hard to produce gas.SOLUTION: An electrolyte comprises: a solvent; a quaternary ammonium salt; and an unsaturated cyclic compound including a nitrogen atom. The unsaturated cyclic compound is an unsaturated heterocyclic compound including a nitrogen atom, provided that the unsaturated cyclic compound does not include a salt of the unsaturated cyclic compound, or an ionic liquid obtained from the unsaturated cyclic compound.SELECTED DRAWING: None |
