Process for the production of electrolyte capacitors
First Claim
1. Process for the producing an electrolyte capacitor which comprises applying a dispersion A) on to a porous body wherein said porous body comprises a porous electrode body of an electrode material and a dielectric which covers the surface of this electrode material, 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, wherein the particles B) of the conductive polymer in the dispersion A) have an average diameter of 1-100 nm, and films produced from particles B) have a specific conductivity in the dry state of greater than 10 S/cm.
