  • SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR MANUFACTURING SAME
    Publication number: 20240079184
    Abstract: A solid electrolytic capacitor includes a capacitor element. The capacitor element includes an anode foil including a base material part and a porous part disposed on a surface of the base material part, a dielectric layer disposed on at least a part of a surface of the anode foil, a solid electrolyte layer covering at least a part of the dielectric layer, and a cathode lead-out layer covering at least a part of the solid electrolyte layer. The anode foil includes an anode section on which the solid electrolyte layer is not disposed, a cathode formation section on which the solid electrolyte layer is disposed, and a separation section located between the anode section and the cathode formation section. A first insulating material is disposed on a surface of the porous part in the separation section. And at least a part of a region of the porous part that is covered with the first insulating material includes a second insulating material.
    Type: Application

  • Electrolytic capacitor and method for production thereof
    Patent number: 11456121
    Abstract: An electrolytic capacitor includes a capacitor element. The capacitor element includes an anode body, a dielectric layer that covers at least a part of the anode body, a solid electrolyte layer that covers at least a part of the dielectric layer, and a cathode lead-out layer that covers at least a part of the solid electrolyte layer. The cathode lead-out layer includes a carbon layer and a silver-paste layer. The carbon layer is conductive and covers at least a part of the solid electrolyte layer. And the silver-paste layer covers at least a part of the carbon layer. The carbon layer contains carbon particles and silver.
