Pengaruh Suhu Aktivasi Fisika Terhadap Elektroda Karbon Aktif Sel Superkapasitor Dari Biomassa Biji Kurma Khalas

---

Physical activation can affect the quality of carbon electrodes so that it can improve the performance of supercapacitor cells. In this study, carbon electrodes were prepared from the Khalas Dates Seeds by varying their physical activation temperatures of 700C, 750C and 800C. Those samples were coded according to their activation temperatures, i.e. BKK-700, BKK-750 and BKK-800. The carbon electrode preparation began with the pre-carbonization process, followed by a chemical activation process using 0.3 M of KOH activator, then carbonized at a temperature of 600C and continued to physical activation under CO2 flow. The BKK-750 sample has the highest density loss with an average density loss of 36%. XRD pattern analysis shows that activated carbon is amorphous which was characterized by the presence of two sloping peaks around the 2θ angle of 22°- 24° and 44°- 46° which represent the orientation of the (002) and (100) hkl planes. The lowest Lc and the highest La are belongs to BKK-750 of 8.56 nm and 11.84 nm, respectively. FTIR analysis shows absorption wave number of 1627 cm-1, 2200-2300 cm-1, 2924 cm-1, and 3425 cm-1 which indicated the presence of functional groups C=O, C=C, C–H and O–H. SEM analysis showed that mesoporous and nanofiber morphological structures with an average diameter of
11.5 nm and 22.8, respectively. The BKK-750 supercapacitor cell had the highest specific capacitance value of 244, 63 F/g-1 and 258, 88 F/g-1, energy density of 33,98 Whkg-1 and 7.11 Whkg-1, and power density of 123.56 Whkg-1 and 125.46 Whkg-1, according to electrochemical analysis using cyclic voltammetry and galvanostatic charge-discharge. The temperature of 750C was found to be the best for manufacturing activated carbon electrodes produced from the biomass of the Khalas Date Palm in improving the performance of supercapacitor cells in this study.
