ABSTRACT
Supercapacitor is energy storage media ultilizes a wide electrode surface and high porosity to obtain a more considerable capacitance value rather than conventional capacitors. The supercapacitor has several main components, one of which is the electrode. Material selection and fabrication of the electrodes play an important role in improving the performance of the supercapacitor. In this research, Carbon electrodes on supercapacitors are made from Citronella leaves using variating temperatures. The fabrication of Carbon electrodes starts from the pre-carbonization with a temperature of 200℃ for 2 hours, chemical activation using KOH activating agent with a concentration of 0.3M, carbonization process using N2 gas with a temperature of 600℃ and physical activation using CO2 gas with temperature variations, of 750℃, 800℃, and 850℃. The optimum physical activation temperature of the Citronella leaf-based Carbon electrode is found at 800℃, with the highest a density reduction percentage of 51.42%. The electrode with a temperature of 800℃ has meso pores with an average size of 39.21 nm and a percentage of carbon content of 88.50%. X-ray diffraction analysis showed that the sample at 800℃ has a semicrystalline structure with a diffraction angle of 2θ at an angle of 24.55º and 44.28º, with the highest Lc/La ratio of 0.76 and the average number of microcrystalline layer (Np) is 2.56. Analysis of electrochemical properties showed that the sample at 800℃ had the highest specific capacitance using CV method and GCD method, are 249.31 F/g and 266.67 F/g respectively.
