Abstract
A wet electrolytic capacitor that contains an anodically oxidized porous anode body, a cathode containing a metal substrate coated with a conductive coating, and a working electrolyte that wets the dielectric on the anode. The conductive coating is formed through anodic electrochemical polymerization ('electro-polymerization') of a precursor colloidal suspension on the surface of the substrate. The colloidal suspension includes a precursor monomer, ionic surfactant, and sulfonic acid, which when employed in combination can synergistically improve the degree of surface coverage and overall conductivity of the coating.
