摘要
Tin-based composites are promising high-capacity anode materials for Li-ion batteries, but they usually exhibit poor cycling stability because of their large volume expansion during the Li uptake and release process. We reported a facile solvothermal method to produce nanosheet-assembled SnS microspheres and a rational strategy to improve the electrochemical performance of SnS microspheres by anchoring on reduced graphene oxide (RGO) networks. The as-prepared SnS/RGO nanocomposites were characterized by XRD, SEM, TEM, TGA, and Raman spectra. The electrochemical results show that the SnS/RGO electrode exhibited high reversible capacity and good cycling stability (delivered a capacity of 760 mAh g(-1) after 100 cycles at a current density of 100 mA g(-1)). The superior electrochemical performance can be attributed to the large available surface area, high conductivity, and fast transportation of electrons and Li-ions; these are benefited from the unique hybrid structure and the synergistic effect between SnS and RGO.
