摘　　要：锂-氧气电池由于具有极高的理论比能量而受到广泛关注,被认为是最具发展前景的下一代高比能二次电池体系.然而,其复杂的反应历程及迟滞的多相反应动力学使其充放电过程的极化严重,造成能量效率低下、倍率性能和循环性能较差等诸多问题,制约了其商业化应用进程.催化是改善反应动力学的关键,因此,氧电极催化剂的设计与开发成为锂-氧气电池的核心问题和研究重点.结合本课题组在这一体系的系统性研究工作,本文综述了近几年来锂-氧气电池氧电极催化的研究进展,分析了各类氧电极催化剂的优缺点,并展望了未来氧电极催化剂的研究方向.Lithium-oxygen battery has received extensive attention due to its ultrahigh theoretical specific energy,and is regarded as the most promising next-generation high specific energy secondary battery system.However,the serious polarization of the charge-discharge process caused by its complicated reaction process and sluggish multiphase reaction kinetics results in many problems,such as low energy efficiency,poor rate performance and poor cycling performance,which restrict its commercial application.Catalysis is the key to improve the reaction kinetics.Therefore,the design and development of oxygen electrode catalysts become the core issue and research focus of lithium-oxygen batteries.By combining the systematic research work of our group on this system,this article reviews the research progress of oxygen electrode catalysis in lithium-oxygen batteries in recent years,and analyzes the advantages and disadvantages of various oxygen electrode catalysts.Besides,a future research direction in oxygen electrode catalysts is prospected.
