Latest Patents

Katsunori Nogami holds a patent for a solid electrolytic capacitor and the process for producing the same. The patent describes a capacitor element fabricated by winding an anode foil and a cathode foil via a separator. This element is impregnated with 3,4-ethylenedioxythiophene and an oxidizing agent to form poly(ethylenedioxythiophene) through chemical polymerization. The use of a nonwoven fabric composed chiefly of synthetic fiber as a separator allows for the favorable formation of a solid electrolyte without reaction with the oxidizing agent. The process includes dipping the capacitor element in water at 80 to 100°C for 1 to 20 minutes to remove the binder in the separator, thus preventing adverse effects on electric characteristics. The oxidizing agent is utilized at a concentration exceeding 40% by weight relative to the solvent, ensuring a high degree of polymerization and a dense, homogeneous solid electrolytic layer.
