钠(Na)电池具有原料成本低、储量大、能量密度较大等特点,是极具发展前景的下一代电池材料之一。生物质具有可持续发展、环境友好、结构多样和高反应活性等优点。由金属-有机骨架(MOF)衍生物和生物质材料制备的多孔碳基材料能够提供主体框架,利用孔结构增大碳的层间间距,保证足够的层间空间用于Na^(+)插入,促进电子转移,从而提高电池的电化学性能。综述了常见的生物质碳基材料、MOF及其衍生物、MOF/生物质复合材料钠电池负极材料的相关研究进展,以期为开发高性能MOF衍生物/生物质碳基复合钠电池电极材料提供理论依据。

Sodium batteries with the inherent advantages of low cost,abundant amount and large energy density is considered as one of the most promising anode materials for the next generation of batteries.Biomass has the advantages of sustainability,eco-friendly property,structural diversity and high reactivity.The porous carbon-based materials made from MOF derivatives and biomasses can provide the main frame,increase the interlayer spacing of carbon by the pore structure enlargement,which can ensure sufficient interlayer space for Na^(+)insertion,and promote electron transfer.Hence,it is used to improve the electrochemical performance of the battery.The application of biomass materials,MOFs and their derivatives,and MOF/biomass composites in sodium battery anodes was reviewed in this article,and their electrochemical performance was also analyzed.This provided a theoretical basis for the preparation of high-efficient MOF derivatives/biomass anode in sodium battery.
