The supercapacitor has a high potential for future energy utilization. The fundamental thing is that compared to batteries, supercapacitors have a higher energy density. This study aims to determine the performance of supercapacitors by utilizing activated carbon based on oil palm empty fruit bunches (OPEFB) as electrodes and adding redox-active to Gel Polymer Electrolyte (GPE). Synthesis of GPE produced by mixing 1 gram of PVA, 1 gram of KOH, and K3[Fe(CN)6] as redox-active with varied weights (0; 0.02; 0.04; 0.06; 0.08; and 0.1 gram) were mixed into 10 ml of deionized water and agitated at 90 oC until a thick homogenous solution was produced. The dehydration process is carried out by left at room temperature and left overnight. Redox-active may increase energy density and specific capacitance by adding pseudocapacitance from the additional electron channel. The rise in the redox-active ratio helps to improve the electrolyte polymer gel's ionic conductivity. Characterization of polymer electrolyte gel with adding K3Fe(CN)6] yielded the energy density of 0.8682 Wh/kg, capacitance value of 30.96 F/g, and the ability to keep the capacitance value of 59.07%. The results of this study offer an alternate approach to overcoming present obstacles and prospects for increasing the energy density of supercapacitor cells. [ABSTRACT FROM AUTHOR] |
