摘　　要： 电化学可充的锌-空气电池具有能量密度高、水系电解液安全、经济性强等特点,在电动汽车、便携式电源以及大型储能方面具有广阔应用前景,是发展绿色清洁能源的重要产业方向。但该电池的空气电极制备过程需要高性能催化剂和特殊的电极结构,这些问题严重制约了锌-空气电池的产业化进程。本文从催化剂开发和电极结构设计两个角度分析空气电极研究开发现状,并对今后催化剂及空气电极的发展趋势进行讨论。开发高活性、高稳定性、价格合理的双功能电催化剂,进行高度结构化的空气电极设计与制备工艺研究;发展适合于批量化制造的三电极结构的锌-空气电池是未来锌-空气电池的重要方向。 Owing to the advantages of high energy density and safe aqueous electrolyte, zinc air batteries become an important research direction in developing green energy, which shows great potential in electric vehicles, portable power supply and large electricity storage systems. However, some issues related to electrocatalysts and electrode structure of the air electrode have seriously restricted the commercialization of zinc air batteries. This paper reviews the possible approaches for developing effective air electrode, including electrocatalyst and electrode configuration, and summarizes present status. Moreover, the development of bifunctional electrocatalysts with high activity, good stability and reasonable cost, air electrode design and manufacturing technology, three electrode configuration suitable for mass production in zinc air batteries are the important direction for novel battery technology in the future.
