    PEMBUATAN ELEKTRODA KARBON AKTIF BERBASIS BIOMASSA TANDAN KOSONG KELAPA SAWIT SEBAGAI MATERIAL UNTUK ELEKTRODA SEL SUPERKAPASITOR
    (Elfitra, 2023-12) Gunawan, Firman
    Porous carbon electrodes based on biomass derivatives have been widely used as the basis for making supercapacitor cell electrodes, because their application can be applied in the long term, sustainable, renewable, easily available, and economically valuable. This research uses biomass derived from empty palm bunches (OPEFB) using ZnCl2 activator and heteroatom doping as a supercapacitor cell carbon electrode. The synthesis process of supercapacitor cell electrodes goes through several stages, namely the hydrothermal carbonization stage with a temperature of 180°C, chemical activation using ZnCl2 chemical activation using ZnCl2 , nitrogen doping as much as 3 grams, carbonization with N2 gas at a temperature of 600°C and physical activation with CO2 gas at a temperature of 800°C. The highest density shrinkage value is owned by the TKKS-M sample which is 57.344%.
