Abstract: MXene materials have been widely used in many fields, such as electromagnetic shielding, sensing, and wastewater treatment. The excellent electrochemical properties of MXene makes it demonstrate broad application prospects in the field of energy storage as well. However, the self-stacking and easy oxidation characteristics of MXene limit its further development. The assembly of MXene into three-dimensional (3D) structural composites is one of the effective way to solve the above problems. The 3D porous structure can provide more channels and active sites for ion transport or storage, which can effectively improve the electrochemical performance. This article reviews the recent researches of MXene composite aerogels. The preparation methods and applications of MXene composite aerogels in energy storage, such as batteries and supercapacitors, are discussed in detail. Finally, the prospects for its future development direction were also presented.
