 US Patent 11955294 Solid electrolytic capacitor containing an intrinsically conductive polymer

Article

Patent abstract

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 a conductive polymer containing repeating thiophene units of a certain formula.
