▎ 摘  要

In the work, an in situ chemical synthesis approach has been developed to fabricate SnO2/reduced graphene oxide nanocomposites in ethanol solution. X-ray diffraction, x-ray photoelectron, Fourier transform infrared and Raman spectrum revealed the formation of SnO2/reduced graphene oxide nanocomposites. Scanning electron microscopy and transmission electron microscopy showed that SnO2 nanoparticles had a crystal size of about 3-4 nm and homogeneously distributed on reduced graphene oxide matrix. The electrochemical performances of the SnO2/reduced graphene oxide nanocomposites as anode materials were measured by the galvanostatic charge/discharge cycling. The results indicated that as-synthesized SnO2/reduced graphene oxide nanocomposites had a reversible lithium storage capacity of 1051 mAh/g and an enhanced cyclability, which can be attributed to increased electrode conductivity and buffer effect to volume change in the presence of a percolated reduced graphene oxide network embedded into the metal oxide electrodes.
