However, their practical deployment is hampered by the notorious polyiodide shuttle effect and sluggish redox kinetics. Herein, an Al-TCPP(Fe) metal-organic framework (MOF) is designed and synthesized with specific functional sites as an advanced iodine host. The unique microporous structure of this MOF provides significant spatial confinement, which effectively suppresses the dissolution and migration of polyiodide intermediates, thereby mitigating the shuttle effect. Furthermore, precisely engineered Fe-N₄ catalytic sites embedded within the MOF framework induce a quantum size effect under naAdvanced materials (Deerfield Beach, Fla.)Quantum Size Effect Synergizes Space-Limited Domain Action for Advanced Aqueous Zinc-Iodine Batteries.PMC12810656E411130705223790472023A395G2023B15151200952024JH1/11700013XDB060040022309179Ma QLi SZhao CXie YChen ZJin MFeng GLi QWang XWang YNie YLuo DfalseQuantum Size Effect Synergizes Space-Limited Domain Action for Advanced Aqueous Zinc-Iodine Batteries.Rechargeable aqueous zinc-iodine batteries (AZIBs) demonstrate immense potential for large-scale energy storage owing to their high theoretical capacity, resource abundance, and low cost.
