 US Patent 11756746 Solid electrolytic capacitor containing an intrinsically conductive polymer

Article

A solid electrolytic capacitor containing a capacitor element is provided. The capacitor element contains a sintered porous anode body, a dielectric that overlies the anode body, a solid electrolyte that overlies the dielectric, and an external coating that overlies the solid electrolyte and includes conductive polymer particles. The solid electrolyte includes an intrinsically conductive polymer containing repeating thiophene units of a certain formula.
