Patent ID: 7377947

Claim:
Process for the production of an electrolyte capacitor, in which, on to a capacitor body at least comprising a porous electrode body of an electrode material, a dielectric, which covers the surface of this electrode material, a solid electrolyte at least comprising an electrically conductive material which completely or partly covers the dielectric surface, is applied a dispersion a) which at least comprises particles b) of an electrically conductive polymer which comprise at least one optionally substituted polyaniline and/or one polythiophene having recurring units of the general formula (I) or of the formula (II) or recurring units of the general formulae (I) and (II) wherein A represents an optionally substituted C 1 -C 5 -alkylene radical, R represents a linear or branched, optionally substituted C 1 -C 18 -alkyl radical, an optionally substituted C 5 -C 12 -cycloalkyl radical, an optionally substituted C 6 -C 14 -aryl radical, an optionally substituted C 7 -C 18 -aralkyl radical, an optionally substituted C 1 -C 4 -hydroxyalkyl radical or a hydroxyl radical, x represents an integer from 0 to 8 and in the case where several radicals R are bonded to A, these can be identical or different, and a binder c) and a dispersing agent d), and, for formation of an electrically conductive polymeric outer layer, the dispersing agent d) is at least partly removed and/or the binder c) is cured, wherein the particles b) of the conductive polymer in the dispersion a) have an average diameter of 70-500 nm.
