Pengaruh Suhu Pra-Karbonisasi Terhadap Kinerja Elektroda Superkapasitor Berbasis Serabut Kelapa Muda

---

ABSTRACT
Supercapacitor is an electrochemical device that combines power delivery capability and charge storage capability. The main components of a supercapacitor are electrodes, separator, electrolyte and current collector. In this study, carbon electrodes are made from coconut fiber biomass waste with variations in the pre- carbonization of 2000C, 2250C and 2500C with the sample codes being SC-200, SC- 225 and SC-250. The fabrication of Carbon electrodes is carried out by several processes, namely pre-carbonization, chemical activation with a ZnCl2 activator of
0.5 M, followed by a carbonization process using N2 gas at a temperature of 6000C and physical activation using C02 gas at a temperature of 7500C. Mass decreases after pre-carbonization by 23.01%, 27% and 36.51%. The highest density value of the samples is found SC-225 with a mass loss percentage value of 41,66%. The X- ray diffraction analysis shows an semicrystaline structure to the (002) and (100) planes reflection with two broad peaks at 2θ angels around 240 and 440, are owned by SC-225 with respective values 12,629 nm and 10,224 nm. Cyclic Voltammetry showed that the SC-225 supercapacitor cell produces the highest capacitance value of 199.82 and the galvanostatic charge-discharge method obtained a much higher capacitance value of 276 F/g. In summary, the temperature SC-225 can be used as an activated Carbon electrode capable of improving the performance of the supercapacitor electrode.
