Latest Patents

Fukui's most recent patent focuses on a method for manufacturing solid electrolytic capacitors, which involves a detailed process to enhance performance and reliability. The invention details the construction of a capacitor element created by winding a cathode foil and an anode foil, each with an oxidized film layer on the surface, with a separator in between. Key to this invention is the adjustment of the binder content in the separator to between 10 to 20% of the total weight, prior to a chemical repair process. Following the repair, the capacitor element undergoes immersion in a mixed liquid that combines a polymerizable monomer and oxidizing agent alongside a selected solvent. This triggers a polymerization reaction, leading to the formation of a solid electrolyte layer. Once completed, the capacitor is enclosed in an outer casing, sealed with rubber, and subjected to an aging process to finalize the creation of the solid electrolytic capacitor.
