MXene for high energy and power density: a perspective

Abstract MXenes as a family of unique 2D materials with high conductivity, atomic thickness, redoxable property and plenty of surface groups have been extensively explored for energy storage. Energy and power densities are always increasing along with the development of controllable synthesis, surface chemical groups and microstructure regulations. Herein, we reviewed present progresses in MXene-based materials for high performance energy storage. Specific discussion was focused on novel structure design, surface group regulation and multivalent ion battery applications. Finally, based on the aforementioned results and discussions, personal perspectives on the MXenes for high energy and power are presented.
