Pengaruh Penambahan Karbon Nanotube Pada Karbon Aktif Berbasis Kulit Biji Mahoni Untuk Elektroda Sel Superkapasitor

The activated carbon electrode obtained from mahogany seed husk has been synthesized through a combination of chemical and physical activation methods for use in the production of supercapacitor cells. This research involves the addition of carbon nanotubes by 2%, 4%, and 8% during the chemical activation process with sample codes KBM-02, KBM-04, and KBM-08, respectively. Characterization of the physical properties of the KBM electrode involves X-ray diffraction, Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy, FTIR, BET, and the characterization of the electrochemical properties of supercapacitor cells using Cyclic Voltammetry and Galvanostatic Charge-Discharge methods. The research results indicate that the microstructure of the electrode exhibits a semi-crystalline structure with peaks (002) and (100) at angles 23º-26º and 42º-45º. The KBM-08 sample shows a nanofiber structure with the highest carbon content reaching 93,13%. The KBM carbon electrode reveals the presence of functional groups such as O-H, C-C, C=C, C≡C, and C=O. N2 adsorption isothermal analysis indicates that the KBM-08 sample has a specific surface area of 528,554 m2/g with mesoporous distribution. Electrochemical analysis of supercapacitor cells using Cyclic Voltammetry and Galvanostatic Charge-Discharge methods with 1 M H2SO4 electrolyte shows that the KBM-08 sample achieves the highest specific capacitance, reaching 366,4 F/g and 350,5 F/g. The addition of carbon nanotubes to the carbon matrix in the KBM biomass-based supercapacitor electrode successfully enhances its performance.
