Patent ID: 8313538

Claim:
A process for the producing an electrolytic capacitor which comprises Subjecting a porous electrode body of an electrode material to anodic oxidation for formation of a dielectric which covers the surface of the electrode material, Applying a dispersion A) on to the porous body wherein the porous body comprises the porous electrode body of the electrode material and the dielectric, wherein said dispersion A)comprises at least particles B) of an electrically conductive polymer and a dispersing agent D), and forming a solid electrolyte which completely or partly covers the dielectric surface, and the dispersing agent D) is at least partly removed and/or cured, in the absence of chemical in situ oxidative polymerization, wherein the maximum anodizing voltage during the anodic oxidation of the porous electrode body is greater than 30 V and the particles B) of the conductive polymer in the dispersion A) have an average diameter of from 1 to 100 nm and wherein the particles B) additionally comprise at least one polymeric anion.
