Toward a New Generation of Low Cost, Efficient, and Durable Metal-Air Flow Batteries
Over the past decades, metal-air flow batteries (MAFBs) have attracted great attention as a promising candidate for the next-generation energy storage systems because of their potential to offer both high performance and scale flexibility, derived from the high energy density of metal-air batteries and the scalability of redox flow batteries. In this article, recent progress of metal-air flow batteries is overviewed, focusing on the structural designs and the advances in materials development. To get an insightful view of the battery features, different categories are introduced on the basis of flow media, working principles, and configurations. In addition, detailed discussion about metal-air flow batteries with aqueous and non-aqueous electrolytes are conducted, containing advances in the structural design and material developments of metal electrodes, air electrodes, and electrolytes. Finally, the challenges and perspectives for future developments are synoptically presented.
