Aqueous zinc-ion batteries have attracted intensive attention because of their safety, low cost, and high theoretical capacity
however, their practical application is hindered by challenges, such as Zn dendrite formation, the hydrogen evolution reaction, and a limited cycle life. Herein, a zinc anode interface is prepared by combining sodium alginate (SA) with hydroxyl and carboxyl groups as a binder and zeolite imidazole framework (ZIF-7) as the ion transport channel. The carboxyl groups in SA exhibit strong Zn
