Aqueous zinc batteries (AZBs) are considered one of the most promising candidates for grid-scale energy storage. However, achieving a stable electrode-electrolyte interface remains challenge developing high-performance AZBs. Herein, taking Zn||phenazine (PNZ) system as prototype, where proton uptake/removal mechanism dominates in cathode, carboxylic acid-functionalized cellulose hydrogel electrolyte is designed to simultaneously solve issues at both anode and cathode interfaces. Specifically, can not only regulate Zn
