Recently, two-dimensional MXenes and MXene-based nanocomposites have become the most important electrode materials because of their unique physical and chemical characteristics. As the electrode of a lithium-ion capacitor, MXenes have exhibited metallic conductivity and plastic layer structure that provide more chemically active interfaces and shortened ion-diffusion lengths, and thus the unbalanced ion kinetics between the anode and cathode can be effectively alleviated. In order to further improve the electrochemical performance of MXenes, the composition, morphology and texture, surface chemistry, and structural configuration of MXenes are extensively investigated. In this mini-review, some recent research and progress of MXenes and MXene-based nanocomposites in lithium-ion capacitors are summarized, which focus on their nanostructure designs and chemical preparation methods, such as prepillaring MXenes, delaminated MXenes, and MXene-based hybrids. Finally, some future perspectives and critical challenges of MXene-based material for lithium-ion capacitor application are also presented and briefly discussed.

锂离子电容器MXene的最新进展。

近年来,二维MXene和基于MXene的纳米复合材料因其独特的物理和化学特性而成为最重要的电极材料。作为锂离子电容器的电极,MXenes具有金属导电性和塑料层结构,可提供更多的化学活性界面和缩短的离子扩散长度,因此可以有效地缓解阳极和阴极之间不平衡的离子动力学。为了进一步改善MXene的电化学性能,广泛研究了MXene的组成,形态和织构,表面化学和结构构型。在本小型审查中,总结了锂离子电容器中MXene和MXene基纳米复合材料的一些最新研究和进展,重点关注其纳米结构设计和化学制备方法,例如预起绒MXene,分层MXene和基于MXene的杂化物。最后,还将介绍和简要讨论基于MXene的材料在锂离子电容器应用中的一些未来前景和关键挑战。
