November 6, 2015Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.AbstractThe present invention relates to an improved method to produce an electrical storage device having useful characteristics such as higher charge density, small volume, long-term reliable charge/discharge cycles, low leakage current, and the like. The dry preunit has useful properties in that it can be stored for long periods prior to contact with a non-aqueous or aqueous electrolyte. When the electrode surfaces are contacted with a non-aqueous or aqueous electrolyte, the novel capacitors produced are useful as a portable power supply in applications such as in defibrillator, electrical vehicles, radiotelephones etc.Other References
