<p>PROBLEM TO BE SOLVED: To provide electrolyte solution, that is gained by having quaternary ammonium salt dissolved in a nonaquous solvent which enables to improve voltage resistance, without increasing the electrical resistance and also provide and electric double-layer capacitor having the electrolyte solution. SOLUTION: This electric double-layer capacitor has electrolyte solution, that is gained by solving such ammonium salt that is represented in formula 1 [in the formula, X represents BF4, PF6, ClO4, AsF6, SbF6, AlCl4 or RfSO3 (Rf=fluoroalkyl group); n represents a number 0 through 5; R1, R2 and R3 are respectively a hydrogen atom, an alkyl group, an aralkyl group, alkynyl group, an aryl goup, or a heterocyclic group, or R1 and R2 may form a ring structure with two carbon atoms that are combined with each other] into a nonaquous solvent.</p> |
