    • The invention discloses a method for forming a conductive polymer with an electrophoretic deposition cell, into porous anode for electrolytic capacitors. The conductive polymer is directly deposited on the oxide layer of the anode body. The electrolytic polymerized conductive polymer material form the cathode in solid electrolyte capacitors. The method allows low ESR capacitors to be produced. The invention provides a high yield and low cost industrial process with efficient materials utilization. The present invention successfully deposits particles from dispersion on continuous, highly insulating dielectric layers using electrophoretic deposition by use of EPD voltage near or above the anode dielectric formation voltage, where the anode body is positively biased relative to the EPD counter electrode, thereby allowing a current to be driven through the dielectric layer.
