Abstract: Electrical devices containing continuous fibers that are infused with carbon nanotubes are described herein. The electrical devices contain at least a first electrode layer and a second electrode layer, where the first and second electrode layers each contain a plurality of continuous fibers that are infused with carbon nanotubes. In some embodiments, the electrical devices can be supercapacitors, further containing at least a base plate, a layer of separator material disposed between the first and second electrode layers, and an electrolyte in contact with the first and second electrode layers. The first and second electrode layers can be formed by conformal winding of the continuous fibers. The electrical devices can contain any number of additional electrode layers, each being separated from one another by a layer of separator material. Methods for producing the electrical devices are also described herein.

Abstract: Electrical devices having a plurality of stacked electrode layers are described. At least one of the electrode layers contains continuous fibers that are infused with carbon nanotubes. The continuous fibers can be disposed upon an electrically conductive base plate. The electrical devices can further contain an electrolyte contacting each electrode layer and a layer of separator material disposed between each electrode layer, in which case the electrical devices can form a supercapacitor. Such supercapacitors can have a capacitance of at least about 1 Farad/gram of continuous fibers. The capacitance can be increased by coating at least a portion of the infused carbon nanotubes with a material such as, for example, a conducting polymer, a main group metal compound, and/or a transition metal compound. Methods for producing the electrical devices are also described.
