%X A natural polymer known as bacterial cellulose (BC), derived from a symbiotic culture of bacteria and yeast (SCOBY), is utilized as the electrodes for the electrochemical double-layer capacitors (EDLC). Bacterial cellulose which can be easily obtained from the local market, possesses an exceptional structure that allows for the elimination of non-biodegradable binders and the use of current collectors in the EDLC electrodes. A green polymer electrolyte system consisting of methylcellulose, potato starch and lithium bromide. This electrolyte demonstrates a conductivity of (1.38 ± 0.54) � 10-4 S/cm, electrochemical stability of 1.3 V, and an ionic transference number of 0.98. The optimized electrolyte is used in the EDLC. Cyclic voltammetry analysis reveals that he fabricated EDLC has a capacitive behavior without any peaks indicating redox reactions. The EDLC undergo charging and discharging for up to 5000 cycles, with specific capacitances of 26 F/g. The EDLC shows a maximum power density of 1730 W/kg, with energy density of 3.6 Wh/kg. © 2024 Penerbit UTM Press. All rights reserved.
