In recent years, thanks to the investigation of the in-depth mechanism, novel cathode material exploitation, and electrolyte optimization, the electrochemical performance of rechargeable Zn-based batteries (RZBs) has been significantly improved. Nevertheless, there are still some persistent challenges locating the instability of the Zn anodes that hinder the commercialization and industrialization of RZBs, especially the obstinate dendrites and hydrogen evolution reaction (HER) on Zn anodes, which will dramatically compromise the cycle stability and Coulombic efficiency. Therefore, various strategies with fundamental design principles focusing on the suppression of dendrite and the HER have been carefully summarized and categorized in this review, which are critically dissected according to the intrinsic mechanisms. Finally, pertinent insights into the challenges and perspectives on the future development of Zn anodes are also emphasized, expecting to supply potential research directions to promote the practical applications of RZBs.
近年来，由于对深入机理的研究、新型阴极材料的开发以及电解质的优化，可充电锌基电池（RZBs）的电化学性能得到了显著提高。然而，仍然存在一些持续的挑战，即锌阳极的不稳定性阻碍了RZBs的商业化和产业化，特别是锌阳极上顽固的枝晶和析氢反应（HER），这将极大地损害循环稳定性和库仑效率。因此，本综述仔细总结并分类了各种基于抑制枝晶和HER的基本设计原则的策略，并根据其内在机制进行了批判性剖析。最后，还强调了对锌阳极未来发展的挑战和前景的相关见解，期望为促进RZBs的实际应用提供潜在的研究方向。
