Abstract Transition bimetallic sulfides show significant promise for energy‐related applications because of their plentiful active sites and synergistic redox activity. However, limited pore size low‐conductivity issues hinder application. The structure NiCo–S with rich sulfur vacancies is first predicted by density functional theory (DFT) calculations. Different vacancy concentrations are modeled DFT calculations, the results confirm that enhance conductivity electrode material more beneficial adsorption OH * species. It verified differential charge electric field formed on surface can lead to strong interfacial interactions electron aggregation, which promotes electron/ion transfer kinetics. Furthermore, nanosheets prepared carbon cloth enriched different (denoted as NiCo‐Sv‐x, x representing concentration vacancies) sulfide etching NiCo‐MOF annealing under H 2 /Ar atmosphere. NiCo‐Sv‐x electrodes obtained applied cathode supercapacitors anode oxygen evolution reaction. Through combining experimental theoretical analysis, effect defect engineering electrochemical performance materials further confirmed.

Abstract The search for advanced electrode materials to solve slow ion diffusion and poor conductivity issues has spurred the development of fast‐charging sodium‐ion batteries (SIBs). Herein, a 2D metallic anode, KCu 4 S 3 , is reported expertly crafted using KSCN molten salt approach, laying foundation SIBs. It found that mixed metal‐valence states within this compound provide substantial advantages, particularly in enhancing high‐rate capability ensuring long‐term durability. mechanism appears facilitate these benefits can be traced formation NaCu 2 intermediate, which assist electron transfer during Na + (de)intercalation. In situ observations confirm sodiation products sodium polysulfide recover original phase upon desodiation. Such distinctive characteristics endow with remarkable electrochemical performances, including an impressive capacity 355 mAh g −1 at 20 A 100% retention 3000 cycles. Moreover, full cell exhibits high energy density 332 Wh kg retains 92% its across 150 cycles 1 . This work opens new horizons field materials, making significant step forward shaping future
