Zinc-air batteries (ZABs) are promising energy storage systems because of high theoretical energy density, safety, low cost, and abundance of zinc. However, the slow multi-step reaction of oxygen and heavy reliance on noble-metal catalysts hinder the practical applications of ZABs. Therefore, feasible and advanced non-noble-metal electrocatalysts for air cathodes need to be identified to promote the oxygen catalytic reaction. In this review, we initially introduced the advancement of ZABs in the past two decades and provided an overview of key developments in this field. Then, we discussed the working mechanism and the design of bifunctional electrocatalysts from the perspective of morphology design, crystal structure tuning, interface strategy, and atomic engineering. We also included theoretical studies, machine learning, and advanced characterization technologies to provide a comprehensive understanding of the structure-performance relationship of electrocatalysts and the reaction pathways of the oxygen redox reactions. Finally, we discussed the challenges and prospects related to designing advanced non-noble-metal bifunctional electrocatalysts for ZABs.
锌空气电池（ZABs）因其高理论能量密度、安全性、低成本以及锌资源丰富，是很有前景的储能系统。然而，氧气的多步缓慢反应以及对贵金属催化剂的严重依赖阻碍了锌空气电池的实际应用。因此，需要找到可行且先进的空气阴极非贵金属电催化剂来促进氧催化反应。在这篇综述中，我们首先介绍了过去二十年锌空气电池的进展，并概述了该领域的关键发展。然后，我们从形态设计、晶体结构调控、界面策略和原子工程的角度讨论了双功能电催化剂的工作机制和设计。我们还纳入了理论研究、机器学习和先进表征技术，以全面理解电催化剂的结构 - 性能关系以及氧氧化还原反应的反应途径。最后，我们讨论了设计用于锌空气电池的先进非贵金属双功能电催化剂相关的挑战和前景。
