  • Publication number: 20120068669
    Abstract: A device and method for harvesting, generating, storing, and delivering energy to a load, particularly for remote or inaccessible applications. The device preferably comprises one or more energy sources, at least one supercapacitor, at least one rechargeable battery, and a controller. The charging of the energy storage devices and the delivery of power to the load is preferably dynamically varied to maximize efficiency. A low power consumption charge pump circuit is preferably employed to collect power from low power energy sources while also enabling the delivery of higher voltage power to the load. The charging voltage is preferably programmable, enabling one device to be used for a wide range of specific applications.

  • Patent number: 7864507
    Abstract: An electric double layer capacitor (EDLC) in a coin or button cell configuration having low equivalent series resistance (ESR). The capacitor comprises mesh or other porous metal that is attached via conducting adhesive to one or both the current collectors. The mesh is embedded into the surface of the adjacent electrode, thereby reducing the interfacial resistance between the electrode and the current collector, thus reducing the ESR of the capacitor.

  • Patent number: 6621687
    Abstract: A microelectronic supercapacitor is amenable to being fabricated using micro electromechanical systems (MEMS) techniques. By utilizing MEMS techniques, the supercapacitor in accordance with the present invention can be formed with volumes <1 mm3. As such, such microelectronic supercapacitor is suitable for use in applications in which only a few millimeters are available for both a supercapacitor and an energy storage device, such as a battery.

  • Publication number: 20030044664
    Abstract: A microelectronic battery which provides increased battery capacity relative to known thin film batteries without the need for increasing the footprint. In order to provide increased capacity, the microelectronic battery in accordance with the present invention is formed from Zn/Air technology as a volumetric energy storage device. As a volumetric energy storage device, the height dimension of the device may be increased relative to known thin film batteries to provide increased battery capacity without the need to increase the footprint dimensions. As such, the microelectronic battery in accordance with the present invention is suitable for various applications which require a relatively high capacity power supply with a relatively small footprint.
