Abstract High redox kinetic barriers and the severe shuttle effect of lithium polysulfides (LiPSs) are two primary challenges for practical deployment lithium‐sulfur (Li–S) batteries. Herein, highly dispersed Co nanoparticles embedded into S, N co‐doped hollow chained carbon sphere (Co@SNC) well‐designed prepared served as an effective host catalyst Li–S Doped S‐atoms can effectively modulate electronic metal‐support interaction between matrix, which induces charge redistribution increased d‐orbital energy levels. Co@SNC provide strong chemical with LiPSs reduce Li + diffusion barrier, anchor accelerate conversion kinetics. The chain‐like structure also synergistically suppresses shuttling enables high sulfur loadings rapid charge/mass transfer. These merit batteries based on reversible capacity, impressive rate performance, prolong cycling stability a low capacity decay 0.024% per cycle over 1700 cycles. Notably, Co@SNC/S electrode still delivers initial 814.9 mAh g −1 superior performance even at loading poor electrolytes.

Abstract Precisely modulating d‐p orbital coupling of single‐atom electrocatalysts for sulfur reduction reactions in lithium‐sulfur batteries maintains tremendous challenges. Herein, a dynamic d‐p‐π modulation is elucidated by unsaturated Fe centers on nitrogen‐doped graphitized carbon (NG) coordinated with trithiocyanuric acid featuring p‐π conjugation to engineer single atom architecture (Fe N4‐ S pπ ‐NG). Intriguingly, this coordination microenvironment the center dynamically reconstituted during charge/discharge processes, because formation trilithium salts rooted from departed axial ligands interfacial coating cathode, and then it recovers initial configuration. Theoretical experimental results unravel that conjugated ligand reinforcing enables charge interaction, thereby strengthening LiPSs adsorption, reducing Li 2 decomposition barrier Fe─S S─Li bonds. Thus, N4 ‐S endow considerable electrochemical performances, highlighting an intriguingly strategy electrocatalysts.
