3D hierarchical networks constructed from interlayer-expanded MoS 2 nanotubes and rGO as high-rate and ultra-stable anodes for lithium/sodium-ion batteries

The MoS 2 nanotubes assembled from MoS 2 nanosheets are wrapped in rGO. The NC-MoS 2 @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.
