Synthesis, Calculations and Energy Storage Applications of High-entropy MXene

High-entropy (HE) MXene is the current research hotspot in the field of two-dimensional (2D) MXene materials. Unlike MXene, which contains only one or rarely two transition metals, HE MXene consists of multiple transition metals, which have both the excellent chemical properties of MXene and inherit the outstanding mechanical properties of HE materials. However, the synthesis and application of HE MXene are not well summarized at present. Here, we summarize the current strategies for synthesizing HE MAX phases and HE MXene, discuss computational studies on the structure as well as function of HE MXene, and demonstrate the application of HE MXene in energy storage and other aspects. Due to its fascinating structural and functional potential and the richness of its design, HE MXene deserves further in-depth study.
