| Abstract: | In aluminium electrolytic capacitor based on formed etched anode foil with high anodic area expansion η and low dielectric film thickness d oxides of the other valve metals (such as Ta, Ti, Nb, Zr etc) and ceramics with high permittivity ε r are added to the formed foil in order to increase it's specific capacitance. Present paper introduces this new method. According to related patent literatures it can be induced to three main ways: physical, chemical and alloying. Thess ideas show that the anode foil aluminium electrolytic capacitor is facing a new technological innovation. |
