Abstract Aqueous Zn ion batteries (AZIBs) have attracted considerable research interest because they offer potential solutions for battery safety concerns, enable long‐duration energy storage, maintain cost‐effectiveness, and support diverse application scenarios. However, the electrochemical performance of AZIBs is hampered by inherent issues arising from water molecules present in water‐based electrolytes. Water are a double‐edged sword AZIBs, which could serve not only as rapid transporter 2+ ions but also instigator anode corrosion, passivation, hydrogen precipitation, narrow window, cathode dissolution, exacerbation zinc dendrite growth aqueous environments. In light these challenges, this review analyzes fundamental principles underlying molecules’ role triggering water‐related problems. It then innovatively summarizes methods to mitigate activity alleviate interface perspective “water repulsing” trapping” including approaches such protection, electrolyte engineering, separator modification, so on, hoping stimulate imagination researchers playing with molecules. should be clarified that modification strategies do exist independently, complementary intersections. Finally, optimization mitigating water‐induced realize high‐efficiency commercially viable proposed, aiming fresh perspectives insights advance AZIB technology.
