Metal sulfides, characterized by high crystalline stability and narrowed band gap, are recognized as effective electrode materials for energy storage in alkaline environments. This study enhances the surface activity Co9S8/Ni3S2 hollow nanorod arrays incorporating phosphorus (P) doping. In situ Raman spectroscopy confirms that P doping facilitates rapid reconstruction media, resulting substantial amounts of oxyhydroxides significantly enhance density supercapacitors. The optimized P–Co9S8/Ni3S2 (1 h) demonstrates a 4.56-fold increase performance over original Co9S8/Ni3S2, achieving capacitance 20.5 F·cm–2 at 3 mA·cm–2 2 M KOH. hybrid supercapacitor device assembled with activated carbon achieves an 1.73 mWh cm–2 power 4.95 mW cm–2, showcasing cycling life 84.6% capacity retention after 10,000 cycles. work effectively reconstructs oxyhydroxide species on electrodes environments through engineering, providing valuable guidance design reconstructions metal sulfide using atom engineering.
