Abstract:
A method for producing an electrode for a capacitor, the method comprising the steps of:providing an electrode charge eliminator; providing a body that is contacted with the electrode charge eliminator, the body comprised of a component A and a component B, wherein the component A is an electrically conductive material which can be partially transformed into a dielectric by oxidization, an absolute amount of free enthalpy &Dgr;G of the oxidation is greater with respect to the component A than with respect to the component B, and a surface energy of the component A is greater than a surface energy of the component B; oxidizing the component A in a surface layer of the body to form an electrode body having a dielectric layer on a surface of the electrode body; and treating the electrode body with heat at a temperature until the component B segregates to the surface of the electrode body and forms an intermediate layer between the electrode body and the dielectric layer.
