Abstract The main factors in improving supercapacitor charge storage are synergistic nano-hierarchical-pore structure modification and natural heteroatom doping strategy. These depend on the reasonable selection of precursors, activators, preparation strategies. In this study, Self-Boron Oxygen-doped carbon porous was achieved through an environmentally benign approach with a dual-solid-cell system electrode design precursor dried sugarcane bagasse, which converted into by dual-atmosphere vertical pyrolysis. Carbon pores studied at high temperatures 800°C-900°C, respectively. pyrolyzed 850°C has porosity as 563.72 m 2 g −1 excellent micropores reaching 92.8%. Morphological properties crystallinity have also been tested to provide support. as-prepared material undergoes significant transformation, resulting well-defined 3D hierarchical pore structure. Through series high-temperature pyrolysis processes, framework is broken down replaced various dopants, particularly boron oxygen, enriching material. Furthermore, element content reaches 87.17%, oxygen amount 12.38% 0.45%, ensuring Faraday reactions initiating pseudo-capacitance active extraordinary physico-chemical behaviour cells based bagasse achieves capacitive 151.6 F 1 A . energy output increases 21 Wh kg , power 167 W acidic medium.
