Abstract:
An electrochemical capacitor comprising a body (1), at least one bank of elements (2) installed therein and leadouts (3) connected thereto;said at least one bank of elements consisting of series connected end elements (4), and internal elements (5); said internal elements (5) comprising: porous electrodes (6, 7) formed of activated carbon particles, a bulk collector, electronic insulting separators (8, 9), and an electron-conducting collector (10); said separators and electrodes are impregnated with an electrolyte; the electrochemical capacitor further comprising hold downs (11) which are interconnected and mounted in the capacitor body, electron-conducting conductors (12) intended for leveling-out voltage in the series-connected elements of the at least one bank; and a coating (14) disposed on the at least one bank of elements (2); said electron-conducting conductors are arranged in openings (13) of each of the separators (8,9); an additional layer (15) being provided between the coating (14) and the body (1);said body is self-supporting and the porous electrodes (6, 7) are elastic.
