Abstract
A method of producing a capacitor electrode includes forming an oxide layer on a foil. The method also includes heating the foil to a target temperature so as to induce defects in the oxide layer. The target temperature is about 450° C. to 560° C. and the duration of heating the foil to the target temperature is less than 4 minutes. The oxide layer is reformed so as to generate a reformed oxide layer that is an aluminum oxide with a boehmite phase and a pseudo-boehmite phase.
