由于安全问题较少、操作条件简单、资源丰富且成本效益高，可充电水系锌离子电池（ZIB）有望成为替代主流锂离子电池的有力候选者。然而，作为负极材料，锌金属不可避免地会受到锌枝晶生长、析氢反应（HER）以及水性电解质中固有腐蚀的影响，这些都严重限制了ZIB的可靠性。为了实现ZIB的商业化，人们开发了各种策略，例如保护涂层的设计、剥/镀锌的主体材料以及插层阳极材料，以克服锌金属的固有局限性。开发 ZIB 的高效阳极需要全面了解结构与性能的关系。本综述旨在全面综述ZIB阳极由于不同的锌储存机制而在锌表面保护涂层和插层阳极材料方面的研究进展。首先，总结了锌金属负极和插层负极材料的局限性。其次，总结了锌阳极保护涂层设计的各种策略和进展。第三，还根据很少报道的插层负极材料的存储机制、材料规格和局限性进行了讨论。最后，提出了开发 ZIB 高性能阳极的潜在研究方向和策略，为未来的研究工作提供了见解。
Rechargeable aqueous zinc-ion batteries (ZIBs) are promising as a competitive candidate to replace the dominant lithium-ion batteries due to fewer safety concerns, simplified operational conditions, abundant resources, and cost-effectiveness. However, as anode material, zinc metal suffers from the inevitable zinc dendrites growth, hydrogen evolution reaction (HER), and inherent corrosion in aqueous electrolytes, which severely restrict the reliability of ZIBs. To realize the commercialization of ZIBs, various strategies such as the design of protective coating layers, host materials for zinc stripping/plating, and intercalated anode materials, were developed to overcome the inherent limitations of zinc metal. A thorough understanding of the structure-performance relationship is required for the development of efficient anodes for ZIBs. This review aims to provide a comprehensive overview of the research progress of ZIB anodes concerning protective coating layers on zinc surfaces and intercalated anode materials due to different zinc storage mechanisms. First, the limitations of zinc metal anode and intercalated anode materials are summarized. Second, A summary of diverse strategies and advancements in protective coating layers design for zinc anode is presented. Third, the rarely reported intercalated anode materials are also discussed based on their storage mechanisms, materials specifications, and limitations. Finally, the potential research directions and strategies for developing a high-performance anode for ZIBs were proposed to offer insights into future research endeavors.
