Abstract MoS 2 /nitrogen-doped carbon hybrid nanorods have been successfully synthesized by a facile simultaneous vapor sulfidization and carbonization method using MoO x /aniline nanorods as the precursor. The obtained hybrid nanorods are composed of MoS 2 with expanded interlayer spacing of 1.02 nm and nitrogen-doped carbon, which exhibit outstanding electrochemical performances as anode materials for lithium-ion batteries including excellent high-rate capability of 667.3 mA h g −1 at 10 A g −1 and outstanding cyclic stability of 1110 mA h g −1 at 1 A g −1 after the charge-discharge process at various current densities. The outstanding lithium storage performances of the MoS 2 /nitrogen-doped carbon hybrid nanorods can be attributed to the synergistic effects of nitrogen-doped carbon and MoS 2 with expanded interlayer spacing. Importantly, the abundant voids caused by the enlarged interlayer spacing of MoS 2 are in favor of the diffusion of lithium ions, and can buffer the volume changes during the charge-discharge process and create additional active sites for lithium ion storage. Moreover, the hybridization of MoS 2 with nitrogen-doped carbon can facilitate the electron transfer and improve the electronic conductivity.
