The cyclability and reversibility of aqueous zinc-ion batteries (AZIBs) are severely hampered by the safety concerns arising from Zn dendrite growth. Therefore, a stable anode with inhibited dendrites side reactions is crucial for AZIBs. Herein, we utilized methyl acetoacetate (MA) as an additive to prevent growth enable highly reversible anodes. Benefiting nucleophilic groups (carbonyl groups) in MA, MA molecules can preferentially adsorb on anode/electrolyte interface (AEI), forming molecular protective layer. Such layers not only regulate migration deposition zinc ions, but also inhibit induced decomposition free H2O at AEI. symmetric cell addition achieves long-term cycling stability 1,500 h 2 mA cm-2 capacity mAh cm-2. In addition, Zn//NVO full using MA-contained electrolyte demonstrates high specific (138.4 g-1) outstanding retention (92.8% after 600 cycles) 1 A g-1. This work provides principle use ester-based additives suppress durable metal
