3D nest-shaped Sb2O3/RGO composite based high-performance lithium-ion batteries.

A Sb2O3/graphene composite with nest-shaped architecture has been successfully prepared. Compared with pure Sb2O3 materials, the Sb2O3/graphene composite exhibits superior electrochemical performance as an anode material in lithium-ion batteries, and this should be attributed to the synergistic effects of the high conductivity of graphene and the novel nest-shaped structure of the composite.
