Pengaruh Penambahan Nitrogen Pada Karbon Aktif Berbasis Tandan Kosong Kelapa Sawit Untuk Aplikasi Baterai Ion Lithium

Biomass is a renewable energy source that can be converted into carbon for lithium-ion battery (LIB) energy storage devices. This study employs oil palm empty fruit bunch (OPEFB) biomass as a carbon anode for LIBs. The nitrogen doping process was optimized using melamine externally with a TKKS : melamine ratio of 1:0, 1:1, and 1:2 were made to achieve a high capacity of LIB. The OPEFB biomass underwent a hydrothermal carbonisation process at 180℃ for 8 hours to produce hydrochar powder. It was chemically activated using a 1.47 M ZnCl2 activating agent and nitrogen-doped externally with a TKKS : melamine ratio 1:1 and 1:2. The carbonization process was then carried out at 800℃ with nitrogen gas for 2 hours. X-Ray Diffraction analysis reveals two broad peaks at angles of 2θ approximately 24º and 42º-44º on the (002) and (100) scattering planes, respectively. Scanning Electron Microscopy analysis indicates the presence of 3D hierarchically connected pores. Energy Dispersive X-ray analysis highlights that the TKKS-2 sample shows the highest nitrogen content of 16.0%. N2 Adsorption-Desorption Isothermal analysis demonstrates that TKKS has a surface area of 307.566 m2.g-1. Fourier Transform Infrared analysis indicates that TKKS activated carbon comprises C=C, C=N, C=O, C-C and C-N functional groups. The electrochemical properties of lithium-ion batteries reveal that the TKKS-2 sample boasts an oxidation value of 0.360 A, validated by Cyclic Voltammetry analysis, charge/discharge capacitive properties of 333 mAh.g-1 and 343 mAh.g-1 were analyzed using Charge-Discharge and Electrochemical Impedance Spectroscopy methods, which revealed Rct results of 29.2 Ω. The study suggests that doping LIBs derived from TKKS biomass with external nitrogen using melamine can enhance their performance.
Keywords: OPEFB, 3D hierarchical carbon, Nitrogen and LIB
