Dramatic enhancement of the electrode performance of Co3O4-graphene nanocomposites can be achieved by adapting exfoliated layered metal oxide nanosheets as an additive for the synthesis of the nanocomposites. Mesoporous Co3O4-CoO2-N-doped graphene nanocomposites are synthesized by the crystal growth of Co3O4 nanoparticles in the presence of the mixture colloidal suspension of exfoliated CoO2 nanosheet and N-doped graphene nanosheet. The incorporation of layered CoO2 nanosheet induces an increase of the surface area of the resulting nanocomposite, which would be related to the diminution of π-π interaction between graphene nanosheets. The present nanocomposites exhibit promising performance as anode materials with the huge discharge capacity, which is much superior to that of CoO2-free homologue. The present study clearly demonstrates that the incorporation of inorganic nanosheets into the graphene-based nanocomposite can provide a powerful and universal methodology to design and synthesize novel efficient electrode materials for lithium secondary batteries.
