A Review on the Recent Progress of Two‐Dimensional (2D) MXenes and Graphene‐Based Anode Materials for Advanced Sodium‐Ion Batteries

The performance of sodium‐ion battery (SIB) is dependent on the inherent characteristics of materials. Extensive research has been done on two‐dimensional (2D) materials due to their exceptional features. MXenes, which are 2D transition metal carbides and nitrides, exhibit outstanding performance in Na + ion batteries due to their high stability, hydrophilic surface, and good conductivity. However, MXenes’ limited capacity and tendency to restack hindered their electrochemical effectiveness. A good approach to address these problems is to design a heterolayered structure using other metal oxides. The electrode synergistically integrated the metallic conductivity of MXene. The recent advancement of MXene layers offers possibilities for the development of numerous novel structures. The versatile chemistry of MXene enables fine‐tuning of its performance in the realm of energy storage. Furthermore, certain unique characteristics of electrochemical energy storage (EES) have been uncovered. Likewise, graphene has gained significant interest as an anode material for SIBs because of its outstanding physical and chemical capabilities. Graphene can enhance electrodes; when paired with other nanomaterials, reaction kinetics can reduce large volume changes and increase electrical conductivity. This review shows a comprehensive analysis of the latest developments in using graphene‐ and MXene‐based anodes for SIBs.
