Karakterisasi Sel Superkapasitor Dari Karbon Aktif Biomassa Sabut Kelapa Berdasarkan Pengaruh Konsentrasi Aktivator Zncl2

---

Biomass-based activated carbon has attracted attention due to its excellent performance as a supercapacitor material. These advantages are derived from its significant surface area and multi-doped heteroatoms, which synergistically enhance the energy storage capacity and conductivity efficiency. In this study, activated carbon was synthesized from coconut fiber through pre-carbonization, chemical activation using ZnCl2 with various concentrations (0.3 M, 0.5 M, and 0.7 M), carbonization in N2 gas at 600°C, and physical activation with CO2 gas at 850°C. The coconut fiber-based activated carbon sample has amorphous properties and functional groups such as C–O, C=C, C≡C, and C–H. The resulting morphology is nanosheets with the highest surface area at SK-0.5 M, which is 618.645 m2/g with micropores of 351.209 m2/g and mesopores of 267.436 m2/g. Optimal activated carbon shows a high carbon content reaching 95.51%. In addition, the presence of self-dopping Oxygen (3.32%), Boron (0.43%), and Phosphorus (0.74%) contributes to providing optimum electrochemical properties showing a specific capacitance value of 176.6 F / g through Cyclic Voltammetry testing and 137.07 F / g through Galvanostatic Charging-Discharging. The results of the study indicate that coconut fiber-based activated carbon has the potential to be used as a supercapacitor electrode. This study provides an understanding of the effect of ZnCl2 concentration on electrode performance where 0.5 M is the optimal condition for high and environmentally friendly energy storage.
Keywords: coconut fiber, activated carbon, ZnCl2 concentration, supercapacitor
