Abstract The challenges of iodine dissolution and polyiodide shuttle behavior severely hinder the development zinc–iodine batteries (ZIBs). Among battery components, binders play a vital role in maintaining mechanical integrity facilitating conversion reaction iodine‐loading cathode ZIBs. Herein, series polyimide‐based polymers rich sulfonic acid group (R‐SO 3 H) are elaborately designed as functional for cathodes. According to spectroscopic characterization theoretical calculation results, PI‐4S binder with R‐SO H, hydroxyl imide groups holds stronger chemisorption capability I 2 /I − species, which effectively helps block active iodine's behavior. As result, corresponding ZIBs deliver reversible capacity 142.7 mAh g −1 over 600 cycles at 0.2 A , high 157.6 500 0.5 50 °C, durable cycling stability 88 15000 4 . This work guides autonomous design multifunctional polymer cathodes facilitates practical application

Aqueous zinc iodine (Zn//I 2 ) batteries have garnered widespread attention due to their high theoretical specific capacity and safety. However, the corrosion of Zn metal anodes, induced by H O molecules polyiodides, leads a short cycling life. Herein, 4‐tert‐Butylcalix[6]arene (TBCX)‐based Janus molecular layers, self‐assembled on interface, are utilized inhibit hydrogen evolution reaction (HER) confine thereby stabilizing anode achieving long‐life Zn//I battery. The hydrophobic tertiary butyl (C(CH 3 functional groups in TBCX layers repel molecules, depressing HER. Significantly, rate at Zn@TBCX is reduced 0.7 μmol h −1 cm −2 . Additionally, hydroxyl (OH) TBCX, with lone pair electrons, demonstrate polar affinity for preventing them from reaching interface thus suppressing polyiodides. Furthermore, zincophilic layer also acts as an ionic redistributor, enabling rapid homogeneous 2+ flux. Owing these attributes, symmetric cell can cycle stably 2200 5 mA , Zn@TBCX//I full cells deliver extended lifespan 6000 cycles A g retention ratio 98.8%.
