水系锌离子电池（AZIB）因其优异的安全性、成本效益和环境友好性而备受关注，被认为是最有前途的大规模储能候选者之一。具有高重量/体积容量的锌金属阳极对于先进的 AZIB 是必不可少的。然而，原始锌金属阳极在实现足够的循环稳定性方面遇到了严峻的挑战，包括枝晶生长、析氢反应、自腐蚀和副产物形成。由于所有这些反应都与电解质/锌界面密切相关，因此微妙的界面工程非常重要。许多针对界面工程的策略已经被开发出来。在这篇评论中，对这些策略和观点的及时更新进行了总结，特别专注于锌的可控合成、锌表面工程、电解液配方和隔膜设计。此外，还阐明了这些策略相应的内在原理，有助于寻求新的策略。最后，讨论了实用AZIB未来发展的挑战和前景，包括进行先进的原位测试、电池模型的统一、一些边界问题等。这篇综述有望指导未来的发展并提供指路明灯水系锌离子电池的发展方向。

Recent Progress on Zn Anodes for Advanced Aqueous Zinc-Ion Batteries

Aqueous Zn-ion batteries (AZIBs) have attracted much attention due to their excellent safety, cost-effectiveness, and eco-friendliness thereby being considered as one of the most promising candidates for large-scale energy storage. Zn metal anodes with a high gravimetric/volumetric capacity are indispensable for advanced AZIBs. However, pristine Zn metal anodes encounter severe challenges in achieving adequate cycling stability, including dendrite growth, hydrogen evolution reaction, self-corrosion, and by-product formation. Because all these reactions are closely related to the electrolyte/Zn interface, the subtle interface engineering is important. Many strategies targeted to the interface engineering have been developed. In this review, a timely update on these strategies and perspectives are summarized, especially focusing on the controllable synthesis of Zn, Zn surface engineering, electrolyte formulation, and separator design. Furthermore, the corresponding internal principles of these strategies are clarified, which is helpful to help seek for new strategies. Finally, the challenges and perspectives for the future development of practical AZIBs are discussed, including the conducting of in advanced in situ testing, unification of battery models, some boundary issues, etc. This review is expected to guide the future development and provi beacon light direction for aqueous zinc ion batteries.
