NOVELTY - The capacitor has opposite polarity electrodes (124a,124b) comprising activated carbon impregnated with aqueous electrolyte, which are arranged on current collector (122). A separator (116) comprising inert, electrically-insulating and ion-permeable material, is arranged between electrodes. A rigid dielectric frame (126) is arranged along the perimeter on surface of collectors, to enclose the electrodes. A capillary comprising porous hydrophobic material, is formed in frame and is extended into portion of electrode, to evacuate discharged gases from electrodes out of the capacitor.    USE - Electric double-layer capacitor for use in low-power electrical equipment, and hybrid or fuel cell vehicles.    ADVANTAGE - The evacuation mechanism provided within the frame provides safe storage of the residual electrolyte seeping out from the electrodes while preventing leakage currents and electrolytic bridging between the capacitor elements during the capacitor fabrication process. The graphite film is provided in the capacitor, so that electrolytic leakage of the capacitor can be prevented effectively, while maintaining the electrical conductivity of capacitor. The frame serves to delimit the electrode region of film, to facilitate the pressing of films together when preparing the capacitor stack. The frame is utilized in conjunction with the electrodes of varying thicknesses, so as to ensure the reproducibility and stable electrical performance characteristics of capacitor at variety of charging currents. The gases are evacuated through the capillaries and notches, so that the swelling and bursting of the capacitor can be prevented. The capillaries allow for the removal of the released gases while keeping inside the aqueous electrolyte, so that the electrolytic dehydration can be minimized. The capillaries are chemically treated in a certain way so as to prevent the escape of gas from around the capillary. The straps are used in the capacitor, so as to prevent the curvature of plates. The electrode dehydration causes an increase of capacitor internal resistance and the increase in the overall voltage of electrodes, while resulting in lower overall voltage limit for electrolysis.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the method for manufacturing electric double-layer capacitor.
