Diatomic Catalysts for Aqueous Zinc‐Iodine Batteries: Mechanistic Insights and Design Strategies

Angewandte Chemie International Edition, Год журнала: 2024, Номер 63(49)

Опубликована: Сен. 13, 2024

Abstract There has been a growing interest in developing catalysts to enable the reversible iodine conversion reaction for high‐performance aqueous zinc‐iodine batteries (AZIBs). While diatomic (DACs) have demonstrated superior performance various catalytic reactions due their ability facilitate synergistic charge interactions, application AZIBs remains unexplored. Herein, we present, first time, DAC comprising Mn−Zn dual atoms anchored on nitrogen‐doped carbon matrix (MnZn−NC) loading, resulting AZIB with capacity of 224 mAh g −1 at 1 A and remarkable cycling stability over 320,000 cycles. The electron hopping along Mn−N−Zn bridge is stimulated via spin exchange mechanism. This process broadens Mn 3d xy band width enhances metallic character catalyst, thus facilitating transfer between intermediates. Additionally, increased occupancy within d‐orbital Zn elevates Zn's d‐band center, thereby enhancing chemical interactions MnZn−NC I‐based species. Furthermore, our mechanism demonstrates potential applicability other Metal‐Zn−NC DACs spin‐polarized atoms. Our work elucidates clear mechanistic understanding provides new insights into catalyst design AZIBs.
