Sulfonic Acid‐Functionalized Zn Single‐Atom Catalysts With Dual Thiophilic and Sodiophilic Sites for High‐Performance Sodium−Sulfur Batteries

Zhiqiang Li, Jiayao Yu, Changlai Wang, Qianwang Chen et autres

ABSTRACT Metal single‐atom catalysts (SACs) for sodium−sulfur (Na−S) batteries typically rely solely on thiophilic binding sites to interact with the polysulfide anions of sodium polysulfides (NaPSs), which intrinsically restricts their catalytic efficiency in sulfur redox reactions. Herein, the sulfonic acid‐functionalized Zn single‐atom …

Coordination‐Bond‐Mediated Biomass Interfaces Govern Zinc Nucleation and Transport in Flow Batteries

Chengnuo Zhao, Changlai Wang, Haichao Huang, Derek L. Ho et autres

ABSTRACT The energy efficiency of aqueous zinc‐iodine flow batteries (AZIFBs) is constrained by unstable Zn electrodeposition/stripping at the anode, originating from inhomogeneous interfacial mass/charge transport and mismatched energy barriers for zinc nucleation vs. growth. Herein, we report a coordination‐bond‐mediated interfacial engineering strategy …
