Abstract Since the first exfoliation of a few atomic layers of transition metal carbides (Ti3C2) from the three-dimensional (3D) MAX phase (Ti3AlC2) in 2011, a family of two-dimensional (2D) layered metal carbides and nitrides also known as MXene has drawn great attention as a promising 2D material in various applications. The hydrophilic nature, excellent conductivity and electrochemical properties make MXene a fascinating 2D candidate for electrochemical energy storage applications. However, the aggregation, restacking, and oxidation of MXene nanosheets (NSs) significantly hinder their performance. To address these issues, an effective and straightforward strategy is to combine MXene with other materials including polymers, metal oxides, and carbon to form MXene nanocomposites. Making MXene nanocomposites with other materials is an effective way to tune the properties of MXene for many applications. In the current research trend, the most important application of MXene-based nanocomposite is electrochemical energy storage due to the improved electrochemical and physicochemical properties. Therefore, this review presents the current advances in MXene nanocomposites, especially for electrochemical energy storage applications.

用于电化学储能应用的 Mxene 基纳米复合材料的最新进展

摘要 自 2011 年第一次从三维 (3D) MAX 相 (Ti3AlC2) 中剥离几个原子层的过渡金属碳化物 (Ti3C2) 以来，一系列二维 (2D) 层状金属碳化物和氮化物也被称为MXene 作为一种有前途的二维材料在各种应用中引起了极大的关注。亲水性、优异的导电性和电化学性能使 MXene 成为电化学储能应用的迷人 2D 候选者。然而，MXene 纳米片 (NSs) 的聚集、重新堆叠和氧化显着阻碍了它们的性能。为了解决这些问题，一种有效且直接的策略是将 MXene 与其他材料（包括聚合物、金属氧化物和碳）结合以形成 MXene 纳米复合材料。用其他材料制造 MXene 纳米复合材料是在许多应用中调整 MXene 性能的有效方法。在当前的研究趋势中，MXene 基纳米复合材料最重要的应用是电化学储能，因为它具有改善的电化学和物理化学性质。因此，本综述介绍了 MXene 纳米复合材料的当前进展，尤其是在电化学储能应用方面。
