摘　　要：水系锌离子电池由于具有较高的能量密度、成本低廉、安全性高和环境友好等优势,因此在智能硬件、小型电动车、大规模储能等领域具有广阔的应用前景。然而,锌金属负极存在的枝晶问题导致电池循环寿命缩短,严重制约了其实际应用。通过分析锌负极的沉积/溶解过程及其可能出现锌枝晶的路径,从人工界面层构筑、基底结构设计及电解液优化三个方面综述了无枝晶锌金属负极的近期研究进展,系统阐述了其主要设计策略及作用机制。最后,对锌金属负极未来发展方向进行了展望。Aqueous zinc-ion batteries(AZIBs)have the vast prospect for applications in intelligent hardware,small electric vehicles,power grids and other fields in that for their benefits of higher energy density,economic viability,intrinsic safety,and environmental friendliness.Nevertheless,short cycle life restricts the practical applications of AZIBs,severe dendrite growth of zinc metal anodes is the main cause of that.Recent research advances on dendritefree zinc metal anodes were reviewed from three aspects of constructing artificial interface layers,designing substrate structures,and optimizing electrolyte through analyzing the plating/stripping process of zinc anodes and the possible paths of zinc dendrites growth,then systematically main design strategies and mechanisms were described.Finally,the future development of zinc metal anodes for AZIBs were summarized and prospected.
