摘要：In recent years, metal–air batteries have attracted extensive research owing to their extremely high theoretical energy density. However, the bottleneck problem of current metal–air batteries is the slow kinetics of oxygen reduction reaction catalysts. Recently, graphene has been widely used in metal–air batteries owing to its many active sites, excellent electrical conductivity, and large specific surface area. To meet the requirements of practical applications, three-dimensional (3D) graphene structures are prepared from two-dimensional graphene nanosheets through various assembly methods, which can tune their mechanical stability, electrochemical properties, and catalytic performance. 3D graphene can act as a catalyst carrier in metal–air batteries, which can not only improve its long-term stability and catalytic activity but also reduce the amount of active components. It is worth noting that the properties of 3D graphene can be further optimized by functionally modifying the surface of graphene. In this chapter, we describe the synthesis techniques of 3D graphene and summarize the properties and functional modifications of 3D graphene. Then we focus on the latest research progress and status of 3D graphene in metal–air batteries. Finally, future directions for enhancing the electrochemical properties of 3D graphene-based metal–air batteries prospect. ? 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
