摘要:
A stacked solid electrolytic capacitor has an anode foil composed of a valve metal, a cathode foil having carbon grains that are evaporated or physically adhered to a surface thereof, a separator and a solid electrolytic layer composed of a conducting polymer. The anode foil, the separator and the cathode foil are stacked in order. The solid electrolytic layer is formed between the anode foil and the cathode foil.

A solid electrolytic capacity has an anode foil 2 having dielectric oxide layer 16 formed on surface thereof, a cathode foil 4 having whiskers 18 that are formed on surface thereof and hold carbide grains 17, a separator paper 6 and solid electrolytic layers 12 formed of a conducting polymer. The anode foil 2 and the cathode foil 4 were rolled together across the separator paper 6. The solid electrolytic layers 12 are formed between the anode foil 2 and the cathode foil 4. Thickness of a layer where the whiskers 18 hold the carbide grains 17 is 1 μm to 5 μm. A method of manufacturing a solid electrolytic capacitor having steps of generating whiskers on surface of a cathode foil after coating carbide grains on the surface of the cathode foil and drying the carbide grains, rolling the cathode foil and an anode foil having dielectric oxide layer formed on surface thereof across a separator, impregnating polymerizable monomers and an oxidizing reagent into the separator, polymerizing the polymerizable monomers and forming solid electrolyte layers between the cathode foil and the anode foil.

A capacitor has a capacitor element, a packaging material, and a sealing material. The capacitor element has an anode foil coupled to an anode terminal, a cathode foil coupled to a cathode terminal, a separator, and an electrolyte layer. The anode foil, the cathode foil and the separator are rolled together. The separator is between the anode foil and the cathode foil. The electrolyte layer is formed between the anode foil and the cathode foil. The packaging material has an opening and packages the capacitor element. The sealing material has a through hole where the anode terminal and the cathode terminal pass through and seals the opening of the packaging material. A given space is provided between the sealing material and the capacitor element. A stopper for securing the space is provided on at least one of the anode terminal and the cathode terminal.

A method of manufacturing a solid electrolytic capacitor includes: rolling an anode foil, a cathode foil and a separator together, the separator being a mixed fiber composed of a chemical fiber and a natural fiber and being between the anode foil and the cathode foil; degrading and removing the natural fiber with enzyme; and forming an electrolytic layer composed of solid polymer between the anode foil and the cathode foil after degrading and removing the natural fiber.
