Charge/Discharge Electrode Properties of Asymmetry Electrochemical Capacitor with High Currents

Electrochemical capacitor with 67 mm length,20 mm width and 170 mm height,was assembled with asymmetry electrode,in which Ni(OH)_2 and activated carbon was used as the anode and cathode electrode materials,respectively.High capacitance was given of 14 000 F with the high discharge velocity of 0.24 A/s if activated carbon with the specific surface area of 1 114 m~2/g was chosen. Moreover,its(capacitance) would keep high and decrease only 9.4% even if it was charged and discharged repeatedly from 1.6 to 0.8 V...
