A porous hedgehog-like Co3O4/NiO/Graphene oxide (denoted as PHCNO/GO) microspheres was ready by the facile solvothermal methodology and annealing therapy in argon environment. The wonderful lithium storage efficiency was obtained resulting from skinny Co3O4/NiO nanosheets with giant particular floor space, considerable pores distributed between Co3O4/NiO nanosheets and GO firmly wrapped on the floor of PHCNO microspheres. Co3O4/NiO nanosheets might present numerous efficient lively websites, after which achieved a excessive reversible particular capability. These pores distributed between Co3O4/NiO nanosheets supplied quite a few diffusion pathways for lithium ions, and relieved the stress from the charging/discharging course of. In the meantime, GO supplied a assist for PHCNO microspheres, after which obtained a wonderful biking stability, the excessive reversible particular capability of 383.9 mA h g-1 was maintained after 1000 cycles at 3000 mA g-1. As well as, GO was benefiting from bettering the conductivity of PHCNO microspheres, after which achieved an excellent price efficiency, the reversible particular capability was as excessive as 526.7 mA h g-1 at 5000 mA g-1. This work supplied a reference for the synthesis of high-performance lithium-ion battery anode supplies.
