Abstract (Research Progress): In recent years, two-dimensional transition metal carbon / nitride (MXene) materials have attracted widespread attention in the field of energy storage due to their unique physical / chemical properties. Among them, the research of two-dimensional Ti3C2Tx materials is the most common. The MAX phase is a type of ternary nitride and / or carbide. Its chemical formula is Mn + 1AXn (n = 1 ～ 3), and M represents a transition metal element (such as Sc, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, etc.), X is carbon and / or nitrogen, and A is mainly a group IIIA or IVA element. According to n, the crystal structure of the MAX phase includes three types. In the MAX phase, the M-X and M-A bond strengths are both high. It cannot be delaminated by shearing or other mechanical methods. Because the M-A bond has higher chemical activity than the M-X bond, a single-layer / few-layer MXenes material can be obtained by chemically etching the M-A bond and assisting the stripping method. The random distribution of surface groups has an important influence on the electrochemical performance. Regulating the type and number of surface groups is an important content of current research. This work introduces the basic structure of the MXene phase and analyzes the relationship between phase structure and performance. The research progress of improving the electrochemical performance of MXene phase materials by means of ion insertion, heat treatment, surface modification, electrode design and element doping is summarized, and the composites of MXenes with carbon materials, oxides, and polymers in the field of supercapacitors are briefly introduced. Application progress. The structure, preparation and electrochemical performance of MXene phase materials are reviewed, and the main problems and future development directions of MXene phase materials in the field of supercapacitors are pointed out.
