dc.description.abstractLinearly interlinked single atoms offer unprecedented physiochemical properties, but their synthesis for practical applications still poses significant challenges. Herein, linearly interlinked iron single‐atom catalysts that are loaded onto interconnected carbon channels as cathodic sulfur hosts for room‐temperature sodium‐sulfur batteries are presented. The interlinked iron single‐atom exhibits unique metallic iron bonds that facilitate the transfer of electrons to the sulfur cathode, thereby accelerating the reaction kinetics. Additionally, the columnated and interlinked carbon channels ensure rapid Na+ diffusion kinetics to support high‐rate battery reactions. By combining the iron atomic chains and the topological carbon channels, the resulting sulfur cathodes demonstrate effective high‐rate conversion performance while maintaining excellent stability. Remarkably, even after 5000 cycles at a current density of 10 A g−1, the Na‐S battery retains a capacity of 325 mAh g−1. This work can open a new avenue in the design of catalysts and carbon ionic channels, paving the way to achieve sustainable and high‐performance energy devices. ©2024 The Authors.
