Abstract: An improved process for forming an electrolytic capacitor is provided. The process comprises: providing an anode with an anode wire extending from the anode body; forming a dielectric on the anode to form an anodized anode; applying a first slurry wherein the first slurry comprises conducting polymer and polyanion, wherein the polyanion and conducting polymer are in a first weight ratio thereby forming a first slurry layer; and applying a second slurry on the first slurry layer wherein the second slurry comprises the conducting polymer and said polyanion and wherein the polyanion and the conducting polymer are in a second weight ratio wherein the second weight ratio is lower than the first weight ratio.

Abstract: A process for preparing a solid electrolytic capacitor comprising application of a non-ionic polyol prior to application of a conducting polymer layer.

Abstract: A process for preparing a solid electrolytic capacitor comprising application of coverage enhancing catalyst followed by application of a conducting polymer layer. Coverage enhancing catalyst is removed after coating and curing.
