This invention discloses a method for manufacturing high specific capacity anodic aluminum foils for electrolytic capacitors, which comprises the steps of: (1) performing a first time electrical corrosion, and (2) performing a second time electrical corrosion. This invention can significantly raise both the capacity and the mechanical properties of the anodic aluminum foils. For a capacitor of 63 V, the specific capacity of the anodic aluminum foils can reach 13.5 muf/cm2, and the tensile strength can reach 20-23 N/cm. This invention is particularly suitable for the corrosion of low voltage aluminum foils (25-100 V), and has such advantages as improved specific capacity and mechanical properties of the aluminum foils, high yiled of the aluminum foils.
