Embodiment Construction

[0025] The present invention is partly related to electrical devices containing a layered structure with carbon nanotubes injected into a substrate (that is, a substrate with carbon nanotubes or a substrate with carbon nanotubes). The electrode material formed by the substrate material), wherein the layered structure is wound into a spiral shape along the central axis. The invention also relates in part to methods for manufacturing such electrical devices. In addition, the present invention also partially relates to equipment used to manufacture such electrical devices.

[0026] As mentioned earlier, supercapacitors generally exhibit much higher capacitance values ​​than traditional capacitors or electrolytic capacitors. Therefore, supercapacitors have received significant attention in energy storage applications such as solar energy harvesting, hydroelectric energy harvesting, and wind power plant energy harvesting. The fast charging and discharging cycle of supercapacitors ma...

Abstract

Electrical devices having electrodes containing carbon nanotubes infused to a substrate are described herein. The electrical devices contain at least a first electrode material containing a first plurality of carbon nanotubes infused to a first substrate and a second electrode material containing a second plurality of carbon nanotubes infused to a second substrate. The first electrode material and the second electrode material are wound in a spiral configuration about a central axis. The electrical devices can be supercapacitors, which also contain at least an electrolyte in contact with the first electrode material and the second electrode material, and a first separator material disposed between the first electrode material and the second electrode material. Methods and apparatuses for making the electrical devices are also disclosed herein.

Description

Technical field [0001] Cross-reference of related applications [0002] The present invention claims priority to U.S. Provisional Patent Application Serial No. 61 / 309,828 filed on March 2, 2010 under 35 U.S.C. §119, which is incorporated herein by reference in its entirety. [0003] The present invention relates generally to energy storage, and more particularly to energy storage using carbon nanotubes. Background technique [0004] Capacitors are electrical components used to accumulate and store charge. Capacitors are different from batteries on at least two levels. First, in a capacitor, charge storage is based on physical charge separation rather than battery chemical charge separation. Second, the charging and discharging rates of capacitors are much faster than the chemical reactions that occur in batteries. [0005] In traditional capacitors, two conductive plates are used to maintain charge separation, and the two conductive plates are separated by a dielectric material. W...
