金属空气电池的理论能量密度比锂离子电池高得多，经常被倡导作为下一代电化学储能的解决方案，应用于电动汽车或电网储能。然而，由于与金属阳极、空气阴极和电解液相关的挑战，它们还没有充分发挥其潜力。在金属空气电池成为现实并大规模部署之前，这些挑战必须得到妥善解决。本文综述了金属空气电池在水(如锌空气)和非水(如锂空气)体系中的研究现状和最新进展。概述了它们发展所面临的一般技术问题，并对可能的解决方案提出了我们的观点。
Metal air batteries have a theoretical energy density that is much higher than that of lithium-ion batteries and are frequently advocated as a solution toward next-generation electro-chemical energy storage for applications including electric vehicles or grid energy storage. However, they have not fulfilled their full potential because of challenges associated with the metal anode, air cathode, and electrolyte. These challenges will have to be properly resolved before metal air batteries can become a practical reality and be deployed on a large scale. Here we survey the current status and latest advances in metal air battery research for both aqueous (e.g., Zn-air) and nonaqueous (e.g., Li-air) systems. An overview of the general technical issues confronting their development is presented, and our perspective on possible solutions is offered.
