METHOD FOR PRODUCING ELECTROLYTE CAPACITORS HAVING HIGH NOMINAL VOLTAGE

摘要

Preparing electrolyte capacitors comprises anodically oxidizing a porous electrode body of an electrode material to form a dielectric, which is coated on the electrode material; applying a dispersion containing at least an electrically conductive polymer particle and a dispersing agent on the porous body containing the porous electrode body; forming a solid electrolyte, in which the dielectric surface is partially or totally coated by the dispersion agent; at least partially removing the dispersion agent and hardening the obtained components.
