A simple method is developed for the preparation of MoSe₂/MoO₂ composite with a flower-like structure for high-performance lithium-ion batteries (LIBs). MoSe₂ could lead to fast and facile movement of Li⁺ due to its larger interlayer spacing. Meanwhile, MoO₂ could protect the lamellar structure of MoSe₂ from being destroyed in the charging/discharging processes to maintain the required active surface to electrolytes. In addition, the flower-like structure of the composite could effectively alleviate the volume expansion during charging/discharging. As LIBs are anode material, MoSe₂/MoO₂ composite demonstrates an excellent specific discharge capacity of 1042 mAh g⁻¹ after 100 cycles at 0.1 A g⁻¹, which is attributed to the synergistic effects of MoSe₂ and MoO₂ in the composite.
