A MoC/C composite material was conveniently synthesized via self-polymerization and pyrolysis. MoC nanoparticles are evenly distributed upon the carbon matrix and feature a cross-linked structure that can efficiently restrain the aggregation of MoC nanoparticles and relieve the volume alteration during the charging/discharging process. Moreover, the carbon material highly improved conductivity and reduced charge transfer resistance of the MoC/C-based electrode; this ensured its long-term stability with superior reversible capacity. At a current density of 1 A g −1 , the MoC/C electrode delivered a reversible specific capacity of 550 mAh g −1 even after 500 cycles, demonstrating excellent electrochemical performance. This MoC-based electrode with an ultralong life cycle could be utilized as an anode material for next-generation lithium-ion batteries.
