<![CDATA[Activated carbon electrodes from orange peel biomass materials for supercapacitor applications with variety of type separator have been prepared. Activated carbon was prepared by pyrolysis process at 800° under N2 gas envinroment. Electrochemical characterization was tested on avariety of separators, i.e, JR-800-W (using Whatman paper number 40), JR-800-E (using eggshell membrane, and JR-800-O (using orange fruit membrane). The results of chemical measurement for the cyclic voltammetry method on the three samples are capacitance values of 191.82 F/g on JR-800-W, 115.08 F/g on JR-800-E, and 94.17 F/g on JR-800-O. The capacitance value in the galvanostatic charge-discharge method are 174.24 F/g with IR drop of 0.067 for sample JR-800-W, 133.22 F/g with IR drop of 0.14 for sample JR-800-E, and 116.8 F/g with IR drop of 0.36 for sample JR-800-O. Whatman paper separators produce good electrochemical properties, indicating the use of separators can affect the performance of activated carbon electrodes for supercapacitor applications.]]>
