Among the various energy storage systems, the rechargeable Zn–air battery is one of the most promising candidates for the consumer electronic market and portable energy sources. In a Zn–air battery, surface/interface chemistry plays a key role in their performance optimization of power density, stability and rechargeable efficiency. A Zn–air battery requires gas-involved ORR (oxygen reduction reaction) and OER (oxygen evolution reaction) reactions, always leading to complex reactions and sluggish kinetic processes at the three-phase interface, in which rational surface/interface nanoengineering at the micro and meso-level play a decisive role. In this review, we cover the influence of surface/interface properties of electrocatalysts and air electrodes on the performance of rechargeable Zn–air batteries, and the latest surface/interface nanoengineering progress from the micro to meso-level is surveyed. Moreover, the surface/interface characteristics of electrocatalysts and air electrodes at the triple-phase interface, which are closely related to the four key parameters of electrical conductivity, reaction energy barrier, reaction surface area and mass transfer behavior, are also described in detail. Based on the discussion of the latest achievements of surface/interface nanoengineering, some personal perspectives on future advanced development of rechargeable Zn–air batteries are presented as well.

可充电锌空气电池的表面/界面纳米工程

在各种储能系统中，可充电锌空气电池是消费电子市场和便携式能源最有希望的候选者之一。在锌空气电池中，表面/界面化学在优化功率密度，稳定性和可充电效率方面起着关键作用。锌-空气电池需要气体参与的ORR（氧还原反应）和OER（氧释放反应）反应，总是导致三相界面处复杂的反应和缓慢的动力学过程，其中在微观表面进行合理的表面/界面纳米工程而中观水平起着决定性的作用。在这篇综述中，我们涵盖了电催化剂和空气电极的表面/界面性质对可再充电锌空气电池性能的影响，并调查了从微观到介观水平的最新表面/界面纳米工程进展。此外，还详细描述了在三相界面处的电催化剂和空气电极的表面/界面特性，这些特性与电导率，反应能垒，反应表面积和传质行为这四个关键参数密切相关。在对表面/界面纳米工程的最新成果进行讨论的基础上，还提出了一些关于可充电锌空气电池未来发展的个人观点。还详细描述了反应能垒，反应表面积和传质行为。在对表面/界面纳米工程的最新成果进行讨论的基础上，还提出了一些关于可充电锌空气电池未来发展的个人观点。还详细描述了反应能垒，反应表面积和传质行为。在对表面/界面纳米工程的最新成果进行讨论的基础上，还提出了一些关于可充电锌空气电池未来发展的个人观点。
