Lithium-sulfur (Li-S) batteries suffer from sluggish kinetics due to the poor conductivity of sulfur cathodes and polysulfide shutting. Current studies on redox catalysis mainly focus adsorption catalytic conversion lithium polysulfides but ignore modulation electronic structure catalysts which involves spin-related charge transfer orbital interactions. In this work, bimetallic phosphorus trisulfides embedded in Prussian blue analogue-derived nitrogen-doped hollow carbon nanocubes (FeCoPS3/NCs) were elaborately synthesized as a host reveal relationship between activity spin state configuration for Li-S batteries. Orbital splitting FeCoPS3 drives transition low-spin high-spin states, generating more unpaired electrons 3d orbit. Specifically, nondegenerate orbitals involved result upshift energy levels, active states. Such tailored increases transfer, influences d-band center, further modifies with potential reaction pathways. Consequently, cell FeCoPS3/NC exhibits an ultralow capacity decay 0.037% per cycle over 1000 cycles. This study proposed general strategy sculpting geometric configurations enable topology regulation battery catalysts.
