However, like other transition metal compounds, Mo-based materials are facing thorny challenges to overcome, such as slow electron/ion transfer kinetics and substantial volume changes during the charge and discharge processes. In this review, we summarize the recent progress in developing emerging 2D Mo-based electrode materials for MIBs, encompassing oxides, sulfides, selenides, carbides. After introducing the crystal structure and common synthesis methods, this review sheds light on the charge storage mechanism of several 2D Mo-based materials by various advanced characterization techniques. The latest achievements in utilizing 2D Mo-based materials as electrode materials for various MIBs (including lithium-ion batteries (LIBs), sodium-ion batteries (SIBs) and zinc-ion batteries (ZIBs)) are discussed in detail. Afterwards, the modulation strategies for enhancing the electrochemical performance of 2D Mo-based materials are highlighted, focusing on heteroatom doping, vacancies creation, composite coupling engineering and nanostructure design.
