摘　　要：MXene作为新兴的二维导电材料,在储能器件的电极和电解质设计及应用等方面引起了科研人员的兴趣。近年来,在锂硫电池研究中,MXene材料优异的导电性及对多硫化物的吸附作用使锂硫电池的性能明显提升。功能化设计可避免MXene材料自堆叠等缺陷,调控其对多硫化物的吸附强度,并赋予MXene催化多硫化物氧化还原反应的功能。本文综述了功能化MXene材料目前主要的制备方式及其对表面官能团的影响,分析了功能化MXene对多硫化物的吸附作用和对穿梭效应的抑制机制及对氧化还原反应动力学的提升机理,讨论了MXene材料在锂硫电池应用中可能存在的问题和改性前景。As a rising two-dimensional conductive material, MXene has attracted researchers’ interest in the design and application of electrodes and electrolytes of energy storage devices. In recent years, the performance of lithium sulfur batteries have significantly improved for the excellent conductivity of MXene material and its adsorption to polysulfides. The functionalized design of MXene can avoid the defects of self-stacking, regulate the adsorption strength of polysulfides, and catalyze the redox reaction of polysulfides. From the perspective of functionalized MXene, the main preparations and their influence on the surface functional group of MXene are reviewed. The adsorption to polysulfides and mechanism of shuttle effect inhibition, and the enhancement mechanism of redox kinetics of functionalized MXene are analyzed. The possible problems and modification prospects of MXene in the application of lithium sulfur batteries are discussed.
