Published: May 28, 2024

Abstract Alloy catalyst is considered to be an important strategy solve the shuttle effect and sluggish kinetics of lithium‐sulfur batteries (LSBs). However, electronic structure alloy on sulfur conversion process has not been effectively analyzed. In this paper, based alloying strategy, such a FeCoNi regulated optimized, adsorption configuration catalytic are defined. The in situ Raman spectroscopy density functional theory (DFT) employed deeply understand mechanism conversion. A cell with modified separator delivers ultra‐low capacity attenuation 0.056% per cycle over 1000 cycles at 3 C. outstanding anti‐self‐discharge performance 8.1% 7 days also achieved. Furthermore, obtained high loading 9.7 mg cm −2 lean electrolyte 5.6 µL s −1 exhibits 81% retention after 100 cycles, providing research prospect for practical application batteries.
