Periodic table showing the elements of MXenes that have been synthesized experimentally. Color code in the periodic table: red (transition metal), yellow (X element), blue (surface groups), and green (A element in MAX phases). Schematics show the general structure of different types of MXenes. (Encyclopedia of Materials: Electronics, 2021, 00015.)

Two-dimensional (2D) materials are versatile choices for electrochemical energy storage applications. A wide variety of ions can be reversibly intercalated and de-intercalated in 2D layers, realizing charge storage and release. Due to their open layered structure and weak Van der Waals interaction between subsequent layers, 2D materials, allow high-rate energy storage with low-ion intercalation resistance. Among 2D materials, transition metal carbide/nitride MXenes are particularly promising electrode materials offering a high charge storage capacity with an ultrahigh rate capability due to their redox-active surface and metallic high electrical conductivity. Since the first discovery of MXene in 2011, there is an ever-growing interest in MXene-related research, such as novel 2D materials synthesis with new stoichiometry, structural and surface characterization and functionalization, and the development of energy storage electrodes.
