A 3D Multilevel Heterostructure Containing 2D Vertically Aligned MoS₂ Nanosheets and 1D Sandwich C-MoS₂-C Nanotubes to Enhance the Storage of Li⁺ Ions.

ABSTRACT: To overcome the disadvantages of the MoS₂ anode for LIBs in terms of low intrinsic conductivity, poor mechanical stability, and adverse reaction with electrolytes, a 3D multilevel heterostructure (VANS-MoS₂-CNTs) has been successfully prepared by a simple hydrothermal method followed by thermal treatment. VANS-MoS₂-CNTs are made up of 2D vertically aligned MoS₂ nanosheets (VANS) and 1D sandwich C-MoS₂-C nanotubes (CNTs). The sandwich-like nanotube is the core part, which is made up of the MoS₂ nanotube covered by carbon layers on both side surfaces. Due to the special heterostructure, VANS-MoS₂-CNTs have good conductivity, high structured stability, and excellent Li⁺/electron transport, resulting in hig
