STACKED CAPACITOR WITH ALUMINIUM ELECTRODES SEPARATED BY CONDUCTIVE POLYMER

摘要

The present invention a capacitor having a plurality of layers of aluminum foil connected to a first electrical terminal of the capacitor and another plurality of layers of aluminum foil connected to a second electrical terminal of the capacitor. The layers of aluminum foil are separated by a polymer such as a conductive organic polymer, so that each layer of polymer physically separates a layer of aluminum foil connected to the first terminal from a layer of aluminum foil connected to the second terminal. In some such embodiments the aluminum foil may be etched to provide greater surface area and capacitance, and also may be oxidized to form a dielectric layer.
