In the current study, the performance characteristics of symmetric super-capacitor (SC) utilizing activated carbon electrodes have been analyzed in an aqueous 1M potassium hydroxide (KOH) solution implemented as the electrolyte. Activated carbon (AC) is derived from Chitosan (CS), which possesses remarkable biodegradable characteristics via the chemical activation method at N2 atmosphere conditions using ZnCl2 as activating agent. To evaluate how CS performs at various activation temperatures of 500, 600, and 700°C, the experiment was conducted. The effect on activation temperature here on porous properties of prepared AC was investigated systematically, using surface area and pore size analysis. Additional morphological properties of synthesized AC were analyzed using the techniques of scanning electron microscopy (SEM) and Energy Dispersive X-Ray Analysis (EDX). Symmetric super-capacitor electrodes were fabricated, and their performance was analyzed in a two-electrode system applyin
