Poly(ethylene oxide) (PEO)-based solid-state lithium-sulfur batteries (SSLSBs) have garnered considerable interest owing to their impressive energy density and high safety. However, the dissolved lithium polysulfide (LiPS) together with sluggish reaction kinetics disrupts electrolyte network, bringing about ionic conductive breakpoints severely limiting battery performance. To cure this, we propose an in situ welding strategy by introducing phosphorus pentasulfide (P

High-entropy alloy (HEA) electrocatalysts have attracted increasing attention for improving sulfur reaction kinetics and anchoring lithium polysulfides (LiPSs) in lithium-sulfur batteries (LSBs). However, fundamentally understanding the relationship between components of HEAs adsorption catalysis LiPSs remains a challenge. Here, FeCoNiMnRu are employed as model to first disclose selective adsorption-catalysis effect LiPSs, induced by competition spin polarization electronegativity Ni−Co−Ru sites HEAs. By correlating electron structure, we find that high-electronegativity Ru induce transfer from Co sites, generating local delocalization, while Ni adopt high-spin state. Specifically, with stronger Ni−S covalency can sustainably anchor electron-delocalized Co−Ru function better LiPS conversion. Consequently, benefiting LSBs FeCoNiMnRu/CNF interlayers deliver exceptional cycling performance (0.06% per cycle over 500 cycles at 1 C, an outstanding areal capacity 11.2 mAh cm−2 0.1 C). This work offers key insights extending enable high-performance LSBs.
