Pengaruh suhu aktivasi fisika terhadap elektroda karbon aktif dari biomassa Sisik ikan gabus (channa striata) pada sel superkapasitor

Supercapacitors are superior energy storage devices that are safe and environmentally friendly with high power density. Supercapacitors consist of electrodes, current collectors, electrolytes, and separators. This study uses snakehead fish scale biomass with variations in physical activation temperature, namely 700°C, 800°C, and 900°C, with sample codes SG700, SG800, and SG900, respectively. The carbon electrode manufacturing process began with pre-carbonization, chemical activation, carbonization using N2 gas, and physical activation using CO2 gas. The highest density shrinkage value was found in sample SG900, which was 21.12%. The SG carbon electrode contained O-H, C≡C, C=C, and PO43-, has an amorphous structure with crystal peaks caused by the crystalline phase of hydroxyapatite (HAp) at an angle of 2θ around 23º-24º and 42º, and has a surface morphology dominated by mesopores. The N2 gas isothermal adsorption-desorption test produced type IV with a hysteresis loop that has a specific surface area of 81.056 m2/g. Electrochemical testing using Cyclic Voltammetry (CV) with 1 M H2SO4 electrolyte on SG900 carbon electrodes produced a specific capacitance of 132.00 F/g. Based on the results of the physical and electrochemical properties of snakehead fish scale carbon electrodes, it can be concluded that physical activation temperature can improve the performance of supercapacitor cell electrodes.
Keywords: Cork fish scales, physical activation temperature, supercapacitor
