3D hierarchical networks constructed from interlayer-expanded MoS₂ nanotubes and rGO as high-rate and ultra-stable anodes for lithium/sodium-ion batteries

Abstract

The MoS2 nanotubes assembled from MoS2 nanosheets are wrapped in rGO. The NC-MoS2@rGO is endowed with ultrahigh capacity, high cycle stability and rate capability. Addition of graphene has a positive effect on battery performance by DFT calculation.
