In summary the successful conversion of novel biomass Argan Pulp into activated carbon was achieved through a two-step process carbonization followed by activation using KOH at different temperatures and ratios (700°C 800°C 850°C) (3:1 4:1). Among samples AP-800-4 exhibited highest specific surface area 3237 m2.g-1 total volume 1.63 cm3.g-1. The optimized porous (AC) electrode used to evaluate performance an Electrochemical Double-Layer Capacitor (EDLC). sample AP-800-3 exhibits high capacitance 460 F.g-1 current density 0.125 A.g-1 1M H2SO4 as electrolyte. Additionally it energy power densities up 16.5 Wh kg?1 ~170 W kg?1 respectively. Furthermore showed excellent cycling stability retaining 99% its after 2500 charge discharge cycles 1A.g-1. electrochemical behavior also investigated 6M Na2SO4 electrolytes. performed more efficiently in electrolyte than KOH. It delivered H2SO4 while lower capacitances 230 255 were observed for Overall differences three electrolytes indicate that choice significantly influences supercapacitor. Optimal outcomes are with Na2SO4 whereas demonstrates inferior performance. ranking can be determined follows: >
