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.
