Abstract: An improved capacitor is provided. The capacitor comprises a working element wherein the working element comprises an anode comprising a first dielectric on the anode, a cathode and a conductive separator between the first dielectric and cathode. The conductive separator comprises a separator and a first conductive polymer wherein the first conductive polymer at least partially encapsulates the separator. A second conductive polymer at least partially encapsulates the first conductive polymer and wherein the first conductive polymer has a higher conductivity than the second conductive polymer. An anode lead is in electrical contact with the anode and a cathode lead is in electrical contact with the cathode.
