Rechargeable zinc-ion batteries (ZIBs) are attractive for large-scale energy storage due to their superiority in resources, safety, and environmental friendliness. However, the lack of suitable ZIBs cathode materials limits their practical applications. In consideration of the excellent electrochemical performance of phosphate materials in monovalent ion (Li , Na ) batteries, they were also employed as ZIBs cathode materials recently and performed well with high potential. But they also suffer from low capacity and poor conductivity, and the energy storage mechanism is not clear yet. This Review provides a state-of-the art overview on the developments of phosphate cathode materials in ZIBs, including NASICON-type phosphates, fluorophosphates, olivine-structured, layered-structured, and novel-structured phosphate materials mainly. This study presents the reaction mechanism and electrochemical performance of phosphate cathode materials in aqueous ZIBs, and future research directions are discussed, which are intended to provide guidance for exploring high-potential cathode materials for ZIBs.
可充电锌离子电池（ZIBs）因其在资源、安全和环境友好性方面的优势，在大规模储能领域具有吸引力。然而，缺乏合适的ZIBs正极材料限制了它们的实际应用。鉴于磷酸盐材料在一价离子（Li⁺、Na⁺）电池中具有优异的电化学性能，它们最近也被用作ZIBs正极材料，并在高电位下表现良好。但它们也存在容量低、导电性差的问题，且储能机制尚不清楚。本综述对ZIBs中磷酸盐正极材料的发展进行了最新概述，主要包括NASICON型磷酸盐、氟磷酸盐、橄榄石结构、层状结构和新型结构的磷酸盐材料。本研究介绍了磷酸盐正极材料在水系ZIBs中的反应机理和电化学性能，并讨论了未来的研究方向，旨在为探索ZIBs的高电位正极材料提供指导。
