摘要：

We report a facile hydrothermal strategy to synthesize the Co3O4/graphene composite as anode material for high-performance lithium-ion batteries. The polyhedral Co3O4 particles are homogeneously anchored on graphene sheets, and the growth mechanism has been discussed. The obtained Co3O4/graphene composite displays large reversible capacity (similar to 840 mAh/g after 50 cycles), excellent cyclic stability, and good rate capability in comparison to pure CO3O4 nanoparticles. The flexible structure of graphene sheets and the strong interaction between graphene and Co3O4 particles are beneficial for providing excellent electronic conductivity, short transportation length for Li+ ions, and elastomeric space to accommodate volume varies upon Li+ insertion/extraction.
