Abstract: Two dimensional (2D) material Mxenes has attracted extensive attention as supercapacitor electrode materials because of its high specific surface area, high conductivity and solution processability. Several preparation methods of Ti3C2Tx MXene such as HF and fluoride based etching, alkali based etching, electrochemical etching and Lewis acid molten salt etching are summarized. The assembly strategies of Ti3C2Tx MXene electrode materials such as vacuum assisted filtration, cationic self-assembly, layer by layer assembly, printing process, assembly of MXene aerogels, hydrogels, and their applications in supercapacitors are reviewed. Many studies have shown that the structure and the electrochemical performance of MXene electrodes is considerably affected by different preparation methods and electrode assembly strategies. The preparation methods and electrode assembly strategies of Ti3C2Tx MXene are compared and summarized, the existing problems in the research are pointed out, and the future research direction of MXene is prospected.
