MOF‐Derived High‐Entropy Biphasic Sulfides for Zn‐I 2 ‐S Synergistic Batteries with Machine‐Learning‐Assisted Prediction and In Situ Synchrotron Spectroscopy

ABSTRACT The practical application of aqueous zinc batteries remains constrained by the intrinsic limitations of monocomponent systems, such as the shuttle effect in Zn‐I 2 batteries and the sluggish kinetics in Zn─S batteries. To overcome these limitations, we developed a Zn‐S‐I 2 synergistic battery that synergistically exploits the complementary advantages of dual redox couples. A bifunctional high‐entropy sulfide (HES) catalyst anchored on N‐doped carbon nanosheets was engineered via a surfactant‐assisted metal‐organic framework (MOF) derivatization route. The entropy‐stabilized HES forms a unique wurtzite/zincblende biphasic structure, creating abundant grain boundaries and synergistic active sites.…
