Abstract
This study is to prepare the activated carbon from rubber seed-shells by \KOH\ activation Activated Carbons (ACs) for the electrochemical double layer capacitors (EDLCs). Impregnation-Activation Method using 2%wt \KOH\ solution as a chemical agent was used. The \BET\ surface area, pore volume and pore size distribution of \ACs\ were characterized using \N2\ adsorption technique. The surface morphology was evaluated with SEM. Electrochemical properties of the prepared \ACs\ electrodes have been studied using cyclic voltammetry (CV) in 30%wt of \KOH\ as electrolyte. All prepared \ACs\ had adsorption isotherm Type I indicating as the pore structure is mainly composed of micropores. Highest specific surface area (620 m2/g) with higher iodine number (639.73 mg/g) was obtained from the carbonization at 900oC. The specific capacitance of the microporous \ACs\ sheet electrode reached 63.2 F/g at 1 mV/s.
