An electrode foil comprising a structure in which particles, which primarily include at least one of valve metal particles having a dielectric constant and ceramic particles, are deposited on a surface of a metal foil.
A method for manufacturing an electrode foil, comprising:
- placing an aluminum foil in a film-forming chamber of an aerosol chamber;
- aerosolizing aluminum powder;
- and
- spraying the aerosolized aluminum powder onto the aluminum foil placed in the film-forming chamber so as to deposit aluminum particles on the aluminum foil.
A method for manufacturing an electrode foil, comprising:
- placing an aluminum foil, a surface of which is subjected to etching treatment, in a film-forming chamber of an aerosol chamber;
- aerosolizing ceramic powder;
- and
- spraying the aerosolized ceramic powder onto the aluminum foil placed in the film-forming chamber so as to deposit ceramic particles on the aluminum foil.
A method for manufacturing an electrode foil, comprising:
- placing an aluminum foil, a surface of which is subjected to etching treatment, in a film-forming chamber of an aerosol chamber;
- aerosolizing a mixture of aluminum powder and ceramic powder;
- and
- spraying the aerosolized mixture of the aluminum powder and the ceramic powder onto the aluminum foil placed in the film-forming chamber so as to deposit aluminum particles and ceramic particles on the aluminum foil.
An electrolytic capacitor comprising:
- an anode foil composed of a metal with a valve action, a cathode layer, and an electrolyte layer interposed between the anode foil and the cathode layer,
- wherein the anode foil has on a surface thereof a dielectric oxide film layer formed by depositing particles having a dielectric constant.
An electrode foil for use in a capacitor, comprising a layer formed by depositing metal particles on a metal foil surface, wherein metal particles are deposited so as to have small gaps therebetween;
- and
- the metal particles are surface treated.
A capacitor comprising an electrode foil,
- the electrode foil comprising a layer formed by depositing metal particles on a metal foil surface, wherein metal particles are deposited so as to have small gaps therebetween;
- and
- the metal particles are surface treated.
