The 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.
