dc.description.abstractThis study focuses on the development of a mesoporous activated graphene oxide (AGO) based electrode derived from Sri Lankan Vein Graphite, aiming to achieve an ultra-high specific capacitance in electrochemical double-layer capacitors (EDLCs). The AGO material is synthesized from Sri Lankan graphite using a cost-effective and environmentally friendly chemical synthesis route. The resulting AGO exhibits a 3-dimensional mesoporous structure with a specific surface area exceeding 700 m2/g, as determined by Brunauer-Emmett-Teller analysis. EDLC electrodes are prepared by mixing synthesized AGO with a binder and conductive additive, and the electrode performance was analyzed while maximizing AGO loading. An enhanced specific capacitance of 529 F/g in 1M HCl electrolyte is achieved, which is among the best-reported values for AGObased electrodes so far. The observed high capacitance is attributed to the high specific surface area, 3-dimensional mesoporous structure with well-connected pores, and the efficient ion and electron transport in the electrode.en_US
