| Summary: | To overcome the disadvantages of the MoS<sub>2</sub> anode for LIBs in terms of low intrinsic conductivity, poor mechanical stability, and adverse reaction with electrolytes, a 3D multilevel heterostructure (VANS-MoS<sub>2</sub>-CNTs) has been successfully prepared by a simple hydrothermal method followed by thermal treatment. VANS-MoS<sub>2</sub>-CNTs are made up of 2D vertically aligned MoS<sub>2</sub> nanosheets (VANS) and 1D sandwich C-MoS<sub>2</sub>-C nanotubes (CNTs). The sandwich-like nanotube is the core part, which is made up of the MoS<sub>2</sub> nanotube covered by carbon layers on both side surfaces. Due to the special heterostructure, VANS-MoS<sub>2</sub>-CNTs have good conductivity, high structured stability, and excellent Li<sup>+</sup>/electron transport, resulting in high discharge capacity (1587 mAh/g at a current density of 0.1 A/g), excellent rate capacity (1330 and 730 mAh/g at current densities of 0.1 and 2 A/g, respectively), and good cyclic stability (1270 mAh/g at 0.1 A/g after 100 cycles).
