Ongoing interest is focused on aqueous zinc ion batteries (ZIBs) for mass‐production energy storage systems as a result of their affordability, safety, and high energy density. Ensuring the stability of the electrode/electrolyte interface is of particular importance for prolonging the cycling ability to meet the practical requirements of rechargeable batteries. Zinc anodes exhibit poor cycle life and low coulombic efficiency, stemming from the severe dendrite growth, and irreversible byproducts such as H2 and inactive ZnO. Great efforts have recently been devoted to zinc anode protection for designing high‐performance ZIBs. However, the intrinsic origins of zinc plating/striping are poorly understood, which greatly delay its potential applications. Rather than focusing on battery metrics, this review delves deeply into the underlying science that triggers the deposition/dissolution of zinc ions. Furthermore, recent advances in modulating the zinc coordination environment, uniforming interfacial electric fields, and inducing zinc deposition are highlighted and summarized. Finally, perspectives and suggestions are provided for designing highly stable zinc anodes for the industrialization of the aqueous rechargeable ZIBs in the near future.

水性可充电锌离子电池中无树突状阳极的策略

由于其价格适中,安全和高能量密度,人们一直将注意力集中在用于批量生产储能系统的水性锌离子电池(ZIB)上。确保电极/电解质界面的稳定性对于延长循环能力以满足可充电电池的实际要求特别重要。锌阳极由于严重的枝晶生长和不可逆的副产物(例如H 2)而表现出较差的循环寿命和低库伦效率。和惰性ZnO。最近,人们在设计高性能ZIB的锌阳极保护方面做出了巨大努力。然而,人们对锌镀层/剥离的内在起源了解甚少,这极大地延迟了其潜在的应用。这篇评论没有关注电池指标,而是深入研究了触发锌离子沉积/溶解的基础科学。此外,突出并总结了调节锌配位环境,均匀界面电场和诱导锌沉积的最新进展。最后,为在不久的将来为水性可充电ZIBs工业化设计高度稳定的锌阳极提供了观点和建议。
