Abstract
Two-dimensional (2D) nanostructures and their hybrids have triggered intensive attention in energy storage and conversion field owing to their structural benefits. This work firstly prepares 2D hybrids of MoS2 nanosheets with B, N co-doped graphene nanosheets as advanced anode material for lithium-ion batteries. The rational use of 2D nanomaterials can supply large surface area for lithium storage and shorten Li+ diffusion length. The smart structure design can not only effectively enhance electrical conductivity of composite electrode, but also relax the volume change of MoS2 upon electrochemical cycling. Due to the structural and compositional advantages, the present sample exhibits excellent anode performance with large and stable lithium storage, as well as high rate capability.
