Title:

Preparation of Mxenes and Its Application in Lithium/Sodium Batteries

Abstract:

Since its discovery in 2011, MXenes have attracted great interest in the field of energy storage due to their unique combination of characteristics such as metal conductivity, hydrophilicity, large interlayer spacing, and rich surface chemical properties. The most significant characteristics of MXene are its large adjustable interlayer spacing and rich surface chemical properties, which make it different from other two-dimensional materials. We mainly discuss the synthesis and pillaring of MXene ultra-thin layers, the preparation of MXene/transition metal sulfide heterostructures through Lewis acid molten salt etching and subsequent in-situ vulcanization treatment, and their applications in lithium/sodium ion batteries.
