Li-air battery has recently emerged as a potentially transformational energy storage technology for both transportation and stationary energy storage applications due to its very high specific energy. However, its practical application is currently limited by the poor power capability, poor cyclability and low energy efficiency, all of which are largely determined by interfacial reactions on oxygen electrocatalysts in air electrode. In this article, we review the fundamental understanding of oxygen electrocatalysis in nonaqueous electrolytes, the status and challenges of oxygen electrocatalysts, and provide a perspective on new electrocatalysts design and development.
