MXenes to MBenes: Latest development and opportunities for energy storage devices

Two-dimensional (2D) transition metal carbide and nitride (MXenes) and 2D transition metal borides are analogs to MXenes and are given the name MBenes. MXenes and MBenes are important 2D nanomaterials with diverse potential in various research domains of physics and chemistry. MBenes offer high conductivity, flexibility, and mechanical properties, attracting attention for energy storage applications such as mono/divalent batteries and supercapacitors. Both theoretical and experimental results confirmed the exciting potential of MBene for energy storage applications. MBenes have demonstrated a broad range of fascinating characteristics and have been extensively researched for their potential uses in energy storage and conversion devices. It is reasonable to anticipate that MBenes will have a bright future. The investigation of MBenes, on the other hand, is still in its early stages, and there are a great deal of expected features and applications that are being investigated. This review aims to provide an overview of recent advancements not only in energy storage applications but also in various other aspects, including synthetic methods, morphological and structural characteristics, and other associated properties of MBene. Finally, this critical review ends with the promising prospects, challenges, and opportunities in MBene advancements.
