摘要

摘要: MXene及其复合材料在二次电池领域得到了广泛的应用。MXene作为一种新型二维过渡金属碳化物层状材料，它的电导率极高，比表面积极大，层状结构独特，表面活性位点众多，离子传输路径极短，力学性能卓越，因此，MXene已经被广泛地应用于储能、吸附、催化等各个领域。以MXene基构建复合材料不仅可以提高导电性，缓解体积膨胀，反过来还可以抑制MXene堆叠，获得更好的电化学性能。本文综述了MXene含氟和无氟的合成方法，分析了MXene及其复合材料在钠、钾离子电池中的应用及性能。最后，阐述了MXene及其复合材料的挑战和前景。

Abstract: MXene and its composite materials have been widely used in the field of secondary batteries. As a new two-dimensional transition metal carbide layered material, MXene has been widely used in energy storage, adsorption, catalysis and other fields. Constructing composites based on MXene not only improves conductivity and alleviates volume expansion, but in turn inhibits MXene stacking and obtains better electrochemical performance. In this paper, the synthesis methods of MXene containing fluorine and fluorine-free are reviewed, and the application and performance of MXene and its composites in sodium and potassium-ion batteries are analyzed. Finally, the challenges and prospects of MXene and its composites are elaborated.
