| Summary: | Uniform one-dimensional (1D) MoS2–C composite nanostructures including nanorods and nanotubes have been produced through a sulfidation reaction in H2S flow using MoOx/polyaniline hybrid nanostructures as the precursor. These MoS2–C 1D nanostructures exhibit greatly enhanced electrochemical performance as anode materials for lithium-ion batteries. Typically, stable capacity retention of 776 mA h g–1 can be achieved after 100 cycles for MoS2–C nanotubes. Even cycled at a high current density of 1000 mA g–1, these structures can still deliver high capacities of 450–600 mA h g–1. The unique 1D nanostructure and the extra carbon in the hybrid structure are beneficial to the greatly improved electrochemical performance of these MoS2–C nanocomposites. |
