Abstract The practical applications of aqueous Zn/I 2 batteries (AZIBs) operating within a wide temperature range are severely hindered by the uncontrolled shutting polyiodide ions (I 3 − / I 5 ) and rampant side reactions. In this study, tolerant polyanionic hydrogel (borax‐bacteria cellulose p (AMPS‐AM)) with ion selective permeability is designed for inhibiting effect reactions under extreme temperatures from −50 to 50 °C. zincophilic R−SO significantly enhances transport Zn 2+ cations promotes uniform growth metal along (002) plane. Moreover, abundant hydrophilic groups in hydrogels effectively suppress both hydrogen evolution reaction formation by‐products reducing water reactivity. Furthermore, theoretical calculations, visualization experiment situ Raman spectroscopy confirm that group hinders shuttle process /I anions through electrostatic repulsion. Consequently, gel electrolyte facilitates ultra‐stable full cell at low current density C over 100 A pouch negative/positive capacity ratio 3.3 exhibits stable performance 350 cycles an impressive high‐areal 2.03 mA h cm −2 , thereby establishing solid foundation its applications.
