Abstract :
MXenes have a series of amazing properties due to their unique structure and tunable chemical functional groups. The application of MXenes in electrochemical energy storage, especially showing high potential in supercapacitor applications, has attracted special attention. Compared to other materials, MXenes have high mechanical flexibility, high energy density, and good electrochemical performance, so they are especially suitable as electrode materials for supercapacitors. However, similar to other 2D materials, due to strong van der Waals forces, MXene layers inevitably undergo stacking, leading to a severe loss of electrochemically active sites. If the layers of MXenes can be suppressed effectively, their electrochemical performance will be enhanced. Structural optimization of MXenes and composite doping of MXenes with other materials are two strategies with significant effects. This review summarizes recent advances in MXene synthesis, fundamental properties, and composite materials with a focus on the latest electrochemical performance of MXene-based electrodes/devices and presents new challenges and opportunities that MXene faces in energy storage
