A Synchronous Strategy to Zn‑Iodine Battery by Polycationic Long‑Chain Molecules

Caption

  • A long chain polycation (Pah⁺) is propos ed to simultaneously regulate Zn anode deposition , mitigate side reactions and stabilize iodine cathode chemistry.
  • The iodophilic and low diffusivity nature of Pah enables effective polyiodide immobilization, suppressing the shuttle effect and ensuring a stable redox environment.
  • The Zn iodine battery delivers high areal capacity (~4 mAh cm-2 at 1 C) and excellent durability, with 95% capacity retained over 1000 cycles.
