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.

Lithium‐ion batteries (LIBs) are indispensable in modern electronic instruments and electric vehicles because of their high energy density long cycle life. However, the performance traditional LIBs is constrained by limited theoretical specific capacities structural stabilities, failing to meet demands next‐generation high‐performance applications. Transition metal sulfides emerging as promising electrode materials due low cost, capacities, superior intrinsic properties. Compared oxides, exhibit enhanced electrical conductivity, faster ion diffusion, multi‐electron transfer capabilities, which collectively enable higher density, better rate performance, improved cycling stability. Flame spray pyrolysis (FSP) offers a scalable, cost‐effective method for synthesizing functional structured materials. This one‐step process facilitates precise control over particle composition, morphology, enabling complex modifications such doping, homogeneous mixing, coating, noble promotion/functionalization. FSP also produces metastable nanoparticle phases allows direct deposition onto electrodes without binders or solvents, streamlining fabrication. The integration synthesis with production continuous chain holds immense potential large‐scale manufacturing LIB electrodes. approach anticipated revolutionize storage technologies, addressing challenges scalability.
