Abstract: A capacitor of the type having a cathode and an anode and an electrolyte disposed between the cathode and the anode, the capacitor comprising an electrochemical cathode comprising an aluminum current collector coated with a finely divided material, an electrolytic anode comprising aluminum coated with aluminum oxide, an electrolyte in contact with the finely divided material on the cathode and the aluminum oxide on the anode.

Abstract: A capacitor having an electrochemical cathode electrode, an electrolytic anode electrode, and a substantially non-aqueous electrolyte disposed between the cathode and anode electrodes. The cathode includes a metal and a finely divided material, i.e. a conducting material with a very high ratio of surface area to volume. The anode includes an oxide forming metal and a corresponding metal oxide. The substantially non-aqueous electrolyte is in contact with the finely divided material forming a double layer electrochemical cathode capacitor. The cathode provides the foundation for interleaving a plurality of anodes with a plurality of cathodes. Insulating layers separate the interleaved anodes from the cathodes.

Abstract: A capacitor of the type having a cathode and an anode and an electrolyte disposed between the cathode and the anode, the capacitor comprising an electrochemical cathode comprising a metal current collector, at least one conductive adhesion layer deposited on the metal current collector, a finely divided material deposited on the adhesion layer, an electrolytic anode comprising an oxide forming metal and a corresponding insulating metal oxide, and an electrolyte in contact with the finely divided material on the cathode and the oxide on the anode.
