Abstract:
Provided is an improved capacitor formed by a process comprising: providing an anode comprising a dielectric thereon wherein the anode comprises a sintered powder wherein the powder has a powder charge of at least 45,000 μFV/g; and forming a first conductive polymer layer encasing at least a portion of the dielectric by applying a first slurry wherein the first slurry comprises a polyanion and a conductive polymer and wherein the polyanion and conductive polymer are in a weight ratio of greater than 3 wherein the conductive polymer and polyanion forms conductive particles with an average particle size of no more than 20 nm.
