Reporters obtained the following quote from the background information supplied by the inventors: "Embodiments of the present invention generally relate to methods of forming an energy storage device. More particularly, embodiments described herein relate to methods of forming electric batteries and electrochemical capacitors.
"Fast-charging, high-capacity energy storage devices, such as supercapacitors and lithium (Li+) ion batteries, are used in a growing number of applications, including portable electronics, medical, transportation, grid-connected large energy storage, renewable energy storage, and uninterruptible power supply (UPS) applications. In each of these applications, the charge time and capacity of energy storage devices are important parameters. In addition, the size, weight, and/or expense of such energy storage devices can be significant limitations. Further, low internal resistance is necessary for high performance. The lower the resistance, the less restriction the energy storage device encounters in delivering electrical energy. For example, in the case of super capacitors, lower internal resistance allows faster and more efficient charging and discharging thereof. In the case of a battery, internal resistance in a battery impacts performance by reducing the total amount of useful energy stored by the battery as well as the ability of the battery to deliver the high current pulses demanded by digital devices.
"Accordingly, there is a need in the art for faster charging, higher capacity energy storage devices that are smaller, lighter, have a longer cycle life, and can be more cost effectively manufactured. There is also a need in the art for components for an electrical storage device that reduce the internal resistance of the storage device."
In addition to obtaining background information on this patent, VerticalNews editors also obtained the inventors' summary information for this patent: "Embodiments of the present invention generally relate to methods of forming an energy storage device. More particularly, embodiments described herein relate to methods of forming electric batteries and electrochemical capacitors. In one embodiment a high surface area electrode for use in an electrochemical device is provided. The high surface area electrode comprises a substrate having a conductive surface, a porous amorphous silicon layer on the conductive surface of the substrate, wherein the porous amorphous silicon layer has a series of interconnected pores, and carbon nanotubes embedded within the series of interconnected pores of the amorphous silicon layer.
