Recent years have witnessed the renaissance of aqueous Zn-ion batteries (AZIBs). Nevertheless, the current development of high-performance AZIBs is confronted by the rapid capacity decay and irreversible cycling of Zn anodes, the culprit of which is unremitted dendritic growth. Harnessing the preferential deposition of Zn is an effective manoeuvre in the sense of alleviating problematic dendrite issues. Meanwhile, numerous studies have revealed that the crystallographic orientations of as-deposited Zn are close related to battery performance. Nonetheless, there is a lack of comprehensive overview to shed light on the formation rules and underlying mechanisms relating to induced orientation. In this review, we summarize the emerging design strategies of steering Zn orientational deposition and elaborate on the mechanistic insights toward the realization of highly reversible Zn anodes. The existing challenges and future outlooks in this realm are proposed at the end of the review to envisage the commercialization of AZIBs.

将定向沉积转向高性能锌金属阳极的新兴策略

近年来见证了水系锌离子电池 (AZIB) 的复兴。然而，目前高性能 AZIBs 的发展面临着快速容量衰减和 Zn 阳极不可逆循环的问题，其罪魁祸首是未缓解的枝晶生长。就减轻有问题的枝晶问题而言，利用 Zn 的优先沉积是一种有效的策略。同时，大量研究表明，沉积态锌的晶体取向与电池性能密切相关。尽管如此，仍缺乏全面的概述来阐明与诱导定向相关的形成规则和潜在机制。在这篇评论中，我们总结了引导 Zn 定向沉积的新兴设计策略，并阐述了实现高度可逆 Zn 阳极的机理见解。在审查结束时提出了这一领域的现有挑战和未来展望，以设想 AZIB 的商业化。
