Aqueous Zn-ion batteries (ZIBs) are promising safe energy storage systems that have received considerable attention in recent years. Based on the electrochemical behavior of Zn in the charging and discharging process, herein we review the research progress on anode materials for use in aqueous ZIBs based on two aspects: Zn deposition and Zn intercalation. To date, Zn dendrite, corrosion, and passivation issues have restricted the development of aqueous ZIBs. However, many strategies have been developed, including structural design, interface protection of the Zn anode, Zn alloying, and using polymer electrolytes. The main aim is to stabilize the Zn stripping/plating layer and limit side reactions. Zn-intercalated anodes, with a high Zn storage capacity to replace the current metal Zn anode, are also a potential option. Finally, some suggestions have been put forward for the subsequent optimization strategy, which are expected to promote further development of aqueous ZIBs.
水系锌离子电池（ZIBs）是很有前景的安全储能系统，近年来受到了广泛关注。基于锌在充放电过程中的电化学行为，本文从锌沉积和锌嵌入两个方面综述了水系锌离子电池负极材料的研究进展。迄今为止，锌枝晶、腐蚀和钝化问题限制了水系锌离子电池的发展。然而，人们已经开发了许多策略，包括结构设计、锌负极的界面保护、锌合金化以及使用聚合物电解质。主要目的是稳定锌的剥离/沉积层并限制副反应。具有高锌存储容量以替代当前金属锌负极的嵌入锌负极也是一种潜在选择。最后，针对后续的优化策略提出了一些建议，有望推动水系锌离子电池的进一步发展。
