Electrolyte mixture, electrolytic capacitor having the same and oxidant mixture for conjugated polymer synthesis

摘要

An electrolyte mixture for an electrolytic capacitor is provided. The electrolyte mixture includes a conjugated polymer, a polyether and a nitrogen-containing compound, or includes the conjugated polymer, the polyether and a nitrogen-containing polymer, or includes the conjugated polymer and a polyether with nitrogen-containing functional groups. The electrolyte mixture provides a very high static capacitance for an electrolytic capacitor having the same.
