FIELD: electricity.
SUBSTANCE: method to make an electrolytic capacitor includes at least a) anode oxidation of a porous electrode body (2) of electrode material to form a dielectric (3), covering the surface of this electrode material; b) application onto the porous body, including at least the porous electrode body (2) of the electrode material and the dielectric (3); of dispersion (A), containing at least particles B) of electroconductive polymer and a disperser D), c) and at least partial removal and/or hardening of the disperser D) to form solid electrolytes (4), the dielectric fully or partially covering the surface, at the same time the maximum voltage of anodic treatment during anode oxidation of the porous electrode body (2) makes more than 30 V, and particles B) of the electroconductive polymer in the dispersion A) have the average diametre from 1 to 100 nm.
EFFECT: low equivalent serial resistance and low leakage current of electrolytic capacitors with solid electrolyte, having high rated voltage.
