- Abstract
Supercapacitors are gaining much attention as electrochemical energy storage for their fast charging rates, high power density, good cycle performance, quicker charge-discharge, longer device life, and abundant materials. According to the storage mechanism, supercapacitors are divided into 3 types; EDLC (Electric Double Layer Capacitor), pseudocapacitor, and hybrid. Activated carbon is an excellent candidate as the primary material for making EDLC supercapacitors, and coal is one of the best precursor materials. Activated carbon can be synthesized by chemical and physical activation, where KOH and ZnCl2 are often widely used. However, several researchers have studied the manufacture of activated carbon using ZnCl2 activators still using a low temperature respectively, under 500℃. However, pore development is influenced by temperature. This research focuses on synthesizing activated carbon from coal using a ZnCl2 activator with different temperature variations at room temperature, 500, 800, and 1100℃. Briefly, the experiment begins with synthesizing coal-activated carbon with temperature variations. Then, the powder obtained was carried out by microstructure measurement, including SEM and XRD. The prime is the primary material for making electrodes and deposited on nickel foam to know its electrochemical performance. Furthermore, the electrodes are arranged with the separator and electrolyte into a coin cell device for electrochemical characteristics to be carried out. The electrochemical measurements include Cyclic Voltammetry (CV), Charge-Discharge (CD), and Electrochemical Impedance Spectroscopy (EIS) using the Gamry potentiostat and Battery Testing Equipment instruments.
