Abstract: Since two-dimensional transition metal carbides (nitrides or carbonitrides) MXenes was first reported in 2011, its family members have been increasing. At present, more than 20 MXenes have been successfully synthesized. With unique layered structure, excellent physicochemical properties and designable surface functional group characteristics, MXenes are considered as promising electrode material. In recent years, some remarkable progress of MXenes and its composite materials are achieved in energy storage. To this end, this review presents the research progress of Ti-based MXenes and its composite materials in Lithium-ion batteries and Sodium-ion batteries. Combined with the preparation methods and characteristics of MXenes, the strategies or mechanisms of improving battery performance are introduced in detail. Finally, the challenges and prospects of MXenes and its composite materials in fabricating high-performance batteries are pointed out.
