<p>Two-dimensional materials attracted significant attention in the development of energy conversion and storage devices due to their unique physical and chemical properties. Among these materials, MBenes as analogous to MXenes, exhibited high surface area, excellent electrical conductivity, and diverse crystalline structures owing to the incorporation of boron. In this study, Mo₄/₃B₂T_x MBene (where T_x represents surface terminations such as O, OH, and F) was synthesized from i-MAB precursor using fluoride salt etching process. The synthesized MBene was employed as an anode material for lithium-ion batteries. The electrochemical performance demonstrated specific capacities of 260.3 and 283 mAh g⁻¹, respectively. In addition, the MBene electrode achieved a coulombic efficiency of 91.96% and retained a specific capacity of approximately 280 mAh g⁻¹ after 100 cycles, indicating excellent cyclic stability. This work broadened the application of Mo₄/₃B₂T_x MBene as a promising anode material for lithium-ion batteries.</p> Graphical abstract <p></p>
