NOVELTY - The device e.g. super capacitor (300), has two electrode layers comprising a set of continuous fibers (302, 305) e.g. continuous carbon fibers, that are infused with carbon nanotubes (303, 306) e.g. metallic carbon nanotubes. A layer of separator material (304) e.g. thin film dielectric substance, is placed between the two electrode layers, where the separator material is permeable to ions of an electrolyte e.g. organic electrolyte. The electrolyte is in contact with the electrode layers. An electrode terminal located on a base plate (301) is connected to the set of continuous fibers.    USE - Electrical device e.g. super capacitor (claimed) such as electric double-layer capacitor, electrochemical double-layer capacitor, super condenser, ultra capacitor and pseudo capacitor, for accumulating and storing electric charge in a hybrid gas-electric vehicle and an energy storage application e.g. solar energy collection, hydroelectric energy collection and wind farm energy collection.    ADVANTAGE - The device is produced by making electrodes with carbon nanotube-infused fibers without need to contact the carbon nanotube-infused fibers with a separate electrode plate, thus allowing design process to incorporate multiple electrode layers to the device, and hence increasing the amount of electrical energy that can be stored in the device. The continuous fibers have closely spaced adjacent windings so as to obtain a larger number of carbon nanotubes per unit area, thus leading to higher electrode layer surface areas and a higher capacitance per unit weight of the continuous fibers. The spacing between the adjacent windings of the continuous fibers can be varied to provide a desired capacitance in the super capacitor of a given size.    DETAILED DESCRIPTION - The continuous fibers comprise a fiber form selected from a group consisting of a fiber tow, fiber tape and fiber ribbon. An INDEPENDENT CLAIM is also included for a method for producing an electrical device.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of super capacitors viewed in parallel to longitudinal axes of continuous fibers of electrode layers.
