A porous hedgehog-like Co3O4/NiO/Graphene oxide (denoted as PHCNO/GO) microspheres was prepared by the facile solvothermal method and annealing treatment in argon atmosphere. The excellent lithium storage performance was obtained due to thin Co3O4/NiO nanosheets with large specific surface area, abundant pores distributed between Co3O4/NiO nanosheets and GO firmly wrapped on the surface of PHCNO microspheres. Co3O4/NiO nanosheets could provide a large number of effective active sites, and then achieved a high reversible specific capacity. Those pores distributed between Co3O4/NiO nanosheets provided numerous diffusion pathways for lithium ions, and relieved the stress from the charging/discharging process. Meanwhile, GO provided a support for PHCNO microspheres, and then obtained an excellent cycling stability, the high reversible specific capacity of 383.9 mA h g-1 was maintained after 1000 cycles at 3000 mA g-1. In addition, GO was benefiting from improving the conductivity of PHCNO microspheres, and then achieved a good rate performance, the reversible specific capacity was as high as 526.7 mA h g-1 at 5000 mA g-1. This work provided a reference for the synthesis of high-performance lithium-ion battery anode materials.
