Pembuatan Dan Karakterisasi Elektroda Karbon Dari Limbah Daun Kelapa Sawit Untuk Aplikasi Superkapasitor Menggunakan Aktivator Zncl2

---

Synthesis of palm leaves biomass waste (DK/Elaeis guineensis Jacq) using the chemical activator ZnCl2 at various concentrations was carried out to obtain optimal physical and electrochemical conditions for the supercapacitor electrode. The research method used is an environmentally friendly and low-cost synthesis that is suitable for producing nanocarbon materials that have high value. Series of processing stages such as drying, particle refinement, chemical activation, and pyrolysis are carried out. This research focuses on the effect of adding concentrations of the chemical activator ZnCl2 0,5 M, 0,7 M, dan 0,9 M to produce nanocarbon materials with the best physicochemical characteristics. The research results show that the DK- ZnCl2-0,7 sample is in the best condition with a carbon percentage reaching 77,02% which is supported by the availability of multi self-doping heteroatom oxygen (21,94%), phosphorus (0,26%), boron (0,31%) and nitrogen (0,48 %) which supports the emergence of properties psudocapacity. Apart from that, the pore structure of nanoparticles in large quantities and reinforced by their amorphous nature is certainly a determining factor in optimizing their application in supercapacitors. These favorable physical conditions can increase the specific capacitance by 75,33 F/g for CV and 124,92 F/g for GCD, with specific energy of 17.35 Wh/kg and specific power of 153,84 W/kg in the GCD test. Electrochemical testing of DK- ZnCl2 samples was carried out in a potential window of 0–1 V with a current of 1 A in 1 M H2SO4 aquous electrolyte. The results of this research show the great potential of palm leaves waste as a supercapacitor electrode material for renewable energy storage development with nanostructure and natural B,P,O,N multi-heteroatom doping for competitive electrochemical performance.
