A superstructural nanocomposite of Mo2N quantum dots@MoO3@nitrogen-doped carbon is synthesized to overcome the disadvantages of poor cycling stability and low ionic/electronic conductivity of the MoO3 anode in lithium-ion batteries. In this novel nanocomposite, Mo2N, which is calculated to demonstrate metallic character by density functional theory, together with the nitrogen-doped carbon nanosheets provides dual enhancement in improving the structural stability and kinetics at the same time. Consequently, an optimized Mo2N quantum dots@MoO3@nitrogen-doped carbon nanocomposite exhibits outstanding electrochemical performance, including a large reversible capacity of 960 mAh g-1 at 100 mA g-1 after 100 cycles, and high rate performance as well as excellent long-term cycling stability over 700 and 500 cycles at 1 and 10 A g-1, respectively.
