Abstract

The rapid development of electric vehicles urgently requires high-energy-density batteries. Recently, metal-air batteries have attracted much attention in industry and academia for their ultra-high theoretical energy densities. However, the practical application of metal-air batteries is severely impeded by multiple drawbacks, including severe side reactions, low energy efficiency, and limited cycle life. Understanding the reaction mechanism of the cell and further developing effective strategies are beneficial for the practical application of metal-air batteries. In the past decade, advanced characterization techniques have accelerated the development of metal-air batteries. In particular, synchrotron radiation-based characterization techniques have been widely applied to the mechanistic study of metal-air batteries due to their non-destructive detection capability and high resolution. In this review, various synchrotron radiation-based characterization techniques are systematically summarized to understand the local structure and chemistry of metal-air batteries, with a special focus on how these advanced techniques can help understand the essence of degradation mechanism and optimization strategies. This progress report aims to highlight the crucial role of synchrotron radiation characterization for mechanism understanding of metal-air batteries.
