Aqueous zinc (Zn)-ion batteries (ZIBs) have garnered significant attention as promising energy storage devices, primarily due to their low cost, high power density, and excellent safety profile. However, the commercial viability of these batteries is hindered by several issues related to the Zn metal anode, including dendritic growth, hydrogen evolution reaction (HER), surface corrosion, and passivation. This review delves into the root causes and key factors influencing these challenges from both electrochemical thermodynamics and kinetics perspectives. Subsequently, viable strategies to mitigate these issues are systematically summarized, including Zn anode reconstruction, artificial solid-electrolyte interphase (SEI) protection, electrolyte formulation optimization, and separator functionalization. Recent research advancements are examined thoroughly, with a focus on the mechanisms behind these approaches and the resulting battery performance. The review also critically assesses the strengths and limitations of these solutions. Finally, we highlight crucial research directions aimed at advancing the practical application of Zn metal anodes in future aqueous ZIBs.
