Exploring MXene-based materials for next-generation rechargeable batteries

Abstract MXenes have attracted widespread attention as a kind of emerging 2D material with unique physical and chemical properties. Due to their low adsorption energy and diffusion barrier for some metal ions, some MXenes have become very promising electrode materials for metal-ion batteries. Because of their unique structures and mechanical properties, MXenes are also used in alkaline metal batteries and lithium-sulfur batteries to maintain the integrity of the electrode structure and improve the stability of the battery’s performance. Therefore, MXenes have been widely used in various new-type battery systems. In order to understand the role of MXenes in various post-lithium-ion batteries and evaluate their application potential in these batteries, in this review, the application of MXenes in various post-lithium-ion batteries is comprehensively summarized. In addition, since the preparation methods and conditions have a great impact on the performance of MXenes, various methods for preparing MXenes have also been summarized. Furthermore, with regard to the current development situation of MXenes, we have also expressed our opinions and discussed their development directions in order to enlighten the readers.
