An electrolyte for driving electrolytic capacitors and electrolytic capacitors using the electrolyte are described. The electrolyte comprises at least one quaternary ammonium salt of aliphatic saturated dicarboxylic acid having from 6 to 10 carbon atoms in total or a quaternary ammonium salt of glutaric acid, dissolved in a solvent comprised of an aliphatic polyol. When applied to an electrolytic capacitor, the electrolyte ensures improvements in loss characteristic and high temperature characteristics with time. Thus, the capacitor has a prolonged life.
