Dual-Site Functional Orchestration Enables Synergistic Anodic Modulation and Cathodic Mooring for Durable Zinc–Iodine Batteries

Caption

  • A dual-site functional orchestration strategy is proposed using 2-imidazolidone to simultaneously reconfigure the anodic solvation structure and suppress the cathodic polyiodide shuttle.
  • The carbonyl (C=O) group modulates Zn2+ solvation to induce preferred (002) deposition, while the imino (N-H) group chemically moors polyiodides via hydrogen bonding, achieving decoupled synergistic regulation.
  • This molecular engineering enables a record-breaking lifespan exceeding 5500 h at 8 mA cm-2 for Zn anodes and durable full-cell cycling with 79.4% capacity retention over 2500 cycles.
