  • ENERGY STORAGE DEVICES
    Publication number: 20090180238
    Abstract: Double-layer energy storage devices and methods for manufacturing thereof are disclosed. Such devices and methods are useful for lessening self-discharge of the double-layer energy storage devices. An energy storage device and methods of manufacture that address the problem of capacitor self-discharge due to electrode misalignment, mismatch and/or unpaired electrodes is provided. The rate of self-discharge of a capacitor is increased when electrodes of electrode pairs are not well matched either by misalignment of the electrodes in one or more electrode pairs (e.g., along a longitudinal side or a terminal end of an electrode), or due to errors in the manufacture of electrodes where the electrodes of an electrode pair are not topographically matched (mismatch). In addition, self-discharge of a capacitor is increased if an unpaired electrode (an electrode without a counter-electrode) exists at the beginning, end or both of a roll or stack of capacitor units.

  • Capacitor with battery form factor housing
    Patent number: 7307830
    Abstract: High reliable energy density capability of double-layer capacitor electrode technology now enables the use of capacitors as supplements to, or replacements for, battery technologies. In one application, when sized to a standard battery form factor, the large end terminal surface areas of such form factors enable that the energy density of capacitors can now be safely used as direct drop-in replacements for batteries.
