With the growing energy demand associated with high safety and low-cost requirement, aqueous zinc-ion batteries (AZIBs) have been considered as one of the most promising next-generation batteries. However, some key issues, such as uncontrollable dendrites growth, severe corrosion, hydrogen evolution and side reactions of Zn anodes during charge/discharge process, have hindered its pragmatic applications. Two-dimensional (2D) materials hold advantages of unique physical and chemical properties, large surface areas and abundant active sites, which have been successfully used to overcome the above shortcomings of Zn anodes in recent years. In this review, the issues and challenges of Zn anodes are outlined. Then, the state-of-the-art progress on Zn anodes modification based on 2D materials such as graphene, 2D metal carbides and nitrides (MXenes), 2D metal-organic frameworks (MOFs), 2D covalent organic frameworks (COFs), 2D transition metal compounds and other 2D materials is discussed in detail. Finally, the perspectives of employing 2D materials in highly reversible Zn anodes are summarized and discussed. Graphical abstract
