Abstract
Provided are a foil for a cathode of a capacitor, which can secure both a high capacitance and a high strength, and a manufacturing method thereof. The foil for a cathode of a capacitor includes an aluminum foil and a carbon-containing layer formed on a surface of the aluminum foil. An interposition layer containing aluminum and carbon is formed between the aluminum foil and the carbon-containing layer. The manufacturing method of a foil for a cathode of a capacitor includes a step of arranging an aluminum foil in a space containing a hydrocarbon-containing substance and a step of heating the aluminum foil.
Claims5
A foil for a cathode of a capacitor, comprising:
- an aluminum foil;
- a carbon-containing layer formed on a surface of said aluminum foil;
- and
- an interposition layer that is formed between said aluminum foil and said carbon-containing layer and contains aluminum and carbon, wherein
- said carbon-containing layer is formed so as to extend outward from the surface of said aluminum foil.
A manufacturing method of a foil for a cathode of a capacitor, comprising the steps of:
- arranging an aluminum foil in a space containing a hydrocarbon-containing substance;
- and
- heating said aluminum foil,
- wherein said step of arranging the aluminum foil involves adhering at least one kind selected from the group consisting of a carbon-containing substance and an aluminum powder to a surface of the aluminum foil, and then arranging the aluminum foil in a space containing a hydrocarbon-containing substance.
