Abstract
A process for forming a solid electrolytic capacitor and an electrolytic capacitor formed by the process. The process includes: providing an anode wherein the anode comprises a porous body and an anode wire extending from the porous body; apply a thin polymer layer onto the dielectric, andforming a dielectric on the porous body to form an anodized anode;applying a first slurry to the anodized anode to form a blocking layer wherein the first slurry comprises a first conducting polymer with an median particle size of at least 0.05 μm forming a layer of crosslinker on the blocking layer; andapplying a layer of a second conducting polymer on the layer of crosslinker.
