Effect of Aqueous Electrolyte to the Supercapacitor Electrode Performance Made from Sugar Palm Fronds Waste

Abstract The effect of aqueous electrolyte to the supercapacitor electrode performance made from Sugar palm ( Arenga pinnata ) fronds waste has been successfully analyzed. preparation activated carbon was used a combination chemical and physical activation methods. conducted using potassium hydroxide with 0.5 M concentration CO 2 gas. electrochemical sugar (SPFs) tested cyclic voltammetry method two-electrode configuration. 1.0 H SO 4 , 6.0 KOH, Na were as electrolytic solutions in this study. specific capacitance SPFs electrodes obtained are 130 F/g for electrolyte, 110 KOH 79 respectively. In addition, properties also parameter indicated shrinkage after processes. Based on XRD pattern, semicrystalline structure. characteristic peaks pre-carbonization based FTIR spectra show slightly different.
