AbstractThe development of an all-solid-state hybrid A1/C electrochemical capacitor (EC) device incorporating electrodes consisting of high surface area carbon material coated with a film of anodized aluminum metal with dielectric oxide film on the surface and a high conductivity Polypyrole polymer electrolyte is proposed. The modeling of the energy density of new A1/C hybrid EC device based on actual cell data reported for carbon EC indicates that the practical energy density of the proposed hybrid A1/C EC device is about 33 Wh/1.The proposed solid-state hybrid A1/C EC device will have several attractive features:a) High cell voltage above 6 volts b) Practical energy density at 6 Volts to be 33 Wh/1 c) Operating temperature range between - 50 degree C and 200 degree C
