Abstract Sulfur offers a high‐energy‐density, low‐cost, and sustainable alternative to traditional battery cathodes, but its practical use is limited by sluggish uneven reaction polysulfide dissolution, necessitating electrocatalytic additives enhance conversion efficiency. Generating unpaired spin electrons has proven effective in enhancing performance Co‐based electrocatalysts. These increase adsorption weakening S─S bonds, facilitating their cleavage during sulfur reduction reactions. This work extends the strategy Fe–Ni‐based catalysts. The synthesis of NiSe 2 Fe‐doped particles reported investigate impact Fe doping on electronic structure, catalytic activity, introduced as coating cathode side Li–S (LSB) separator. Experimental analyses first‐principles calculations reveal that Fe‐rich cores surface density states at Fermi level introduce electrons, boosting LiPS conversion. synergistic effects significantly improve performance, cycling stability, overall LSB cells. Specifically, cells based ‐based separators achieve specific capacities 1483 mAh g⁻¹ 0.1C 1085 1C, along with remarkable retaining 84.4% capacity after 800 cycles. High sulfur‐loading tests further validate multifunctional membrane's effectiveness, showing significant retention reduced loss.
