Abstract

The present invention discloses a manufacture method for a solid state capacitor unit used for increasing the capacitance, comprising the steps of: printing a slurry or a glue solution containing metal particles on the surface of a tinsel; performing heat treatment or electrochemical treatment to form a dielectric oxide film; immersing the tinsel in a mixed liquor containing 3,4-ethylenedioxythiophene, P-ferrous benzene sulfonic acid and 1-butanol until a preset position; forming a solid electrolyte layer composed of an electroconductive high polymer 3,4-ethylenedioxythiophene through chemical oxidation coincidence on the dielectric oxide film, and repeating this step for a plurality of times; immersing the tinsel with the solid electrolyte layer already formed in a solution which can dissolve carbon powders in an aqueous solution or an organic solvent; drying the tinsel under preset temperature and time conditions to form a carbon layer; and then forming a silver-coated layer on the surface of the carbon layer, thereby obtaining a capacitor component. The manufacture method for the solid state capacitor unit used for increasing the capacitance has the advantage of being able to greatly increase the capacitance.
