Supercapacitors are receiving considerable attention as energy storage devices for portable and wearable electronics. Their large-scale commercialization hinges on the design development of cost-effective, stable electrode materials with high surface area exceptional conductivity. This study reports synthesis an organic linker-based three-dimensional reduced graphene oxide (3D-rGO) a potential material high-energy supercapacitors. Characterization shows that crafted 3D-rGO is robust microporous 3D network specific 930 m2/g. Electrochemical tests reveal possesses outstanding charge capabilities, achieving capacitance approximately 470 F/g at 10 A/g density around 65.3 Wh/kg power 5000 W/kg. Additionally, it exhibits cyclic stability, retaining 120% its after cycles. A prototype flexible symmetric device utilizing PVA-H2SO4 gel electrolyte 44 F/g, 12.05 (at 2 A/g), impressive 98.4% retention 10,000 cycles 5 A/g. These findings underscore cost-effective highly efficient applications.
