摘　　要：钠离子电池是近年来热门研究的二次离子电池之一,具有成本低、资源丰富的优点。但钠的原子质量和离子半径较大,导致钠离子电池结构形变,影响其电化学性能。MXene是一种新型的二维层状结构材料,具有高导电性、高可塑性、高耐腐蚀性和大比表面积的特性,在钠离子电池中具有广泛的应用。但MXene作为电极材料时,由于层间的范德华力使得片层易再次堆叠,从而减少了表面活性位点,加长了离子扩散路径,进而影响了钠离子电池的比容量和倍率性能。本文综述了MXene材料在钠离子电池负极中的研究进展,介绍了MXene材料的基本性质和制备方法,详细论述了MXene材料优化改性的方法和储钠机制,总结了MXene在钠离子电池负极实际应用中面临的困难和挑战,并展望了MXene材料进一步发展的方向,希望对MXene材料的实际应用有所启发。Sodium-ion battery is one of the most popular secondary ion batteries studied in recent years,which has the advantages of low cost and abundant resources.However,the large atomic mass and ionic radius of sodium lead to structural deformation of sodium-ion batteries,which affects their electrochemical performance.MXene is a novel two-dimensional layered structural material with high conductivity,high plasticity,high corrosion resistance,and large specific surface area,which has been widely used in sodium-ion batteries.However,when MXene is used as an electrode material,their layers are easy to re-stacked due to the van der Waals force between the layers,which reduces the surface-active sites and lengthens the ion diffusion paths,thus affecting the specific capacity and rate performance of sodium-ion batteries.This paper reviews the research progress of MXene as anodes of sodium-ion batteries.It introduces the basic properties and preparation methods of MXene,discusses the modification and optimization methods and the sodium storage mechanism of MXene in detail.It also summarizes the difficulties and challenges faced by MXene in the practical application as anodes of sodium-ion batteries and looks forward to the direction of further development of MXene.It is hoped that this will strengthen the practical application of MXene.
