| Summary: | Highlights 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. |
