MoS 2 is cognized as a promising Lithium-ion battery (LIB) anode material. However, its unsatisfied conductivity and instability hinder its rate performance and cycling stability. Herein, we design a simple strategy to prepare MoS 2 /N-doped carbon (denoted MoS 2 @N–C) nanotubes as anode materials for LIBs. The unique hybrid architecture composed of MoS 2 nanosheets and N–C nanotube achieves excellent electrochemical performance with an exceptional rate capacity (1338 mAh g−1 at 0.2 A g−1) and exceptionally stable cyclic performance (1411 mAh g−1 after 1000 cycles at 1.0 A g−1). The unique hybrid hollow architecture of MoS 2 @N–C provides a new pathway to designing hollow structures for high performance LIBs. [Display omitted] • MoS 2 @N–C nanotube was successfully developed by a facile template method. • The strong bonding between MoS 2 and N–C improves the structural stability. • MoS 2 @N–C nanotube exhibits an excellent cycle performance and rate capability. • The method can be extended to many high-performance MoS 2 composite anodes.
