MoS2 nanosheets on B, N co-doped graphene nanosheets for active lithium storage.

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 MoS 2 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 MoS 2 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.
