Abstract:

Metal-O2 batteries have great potential in the fields of wearable electronic devices and energy storages.However,poor stability and low energy efficiency limit further improvement in their electrochemical performance.Electrochemical oxy-gen reduction reaction(ORR) and oxygen evolution reaction(OER) play a vital role in the performance of metal-O2 batteries. The research trend focus on the development of catalysts as electrodes with high catalytic activity and good stability.Carbon materials have been widely used as conductive framework support and electro-catalysts for Metal-O2 due to their excellent electrical conductivity and diverse structures,which have been become the research hotspot.In this paper,the research of non-metal heteroatomic doped carbon materials,transition metal and its derivatives doped carbon materials,and single-atom cata-lysts as mono-functional or bi-functional catalysts were reviewed.Their application in metal-O2 batteries were introduced in detail.The existing problems of air-electrode catalyst were summarized,and the future development direction was prospected.

Key words: metal-O2 battery, carbon materials, hetero-structures, catalysts
