Sn2Nb2O7-GO nanocomposite was prepared via a facile hydrothermal process. The sample presented that Sn2Nb2O7 nanocrystals were homogeneously dispersed and tightly anchored on the surface of the GO nanosheets. The GO nanosheets not only act as a buffer matrix to promote the structural integrity of the active material, but also serve as a conductive media to accelerate the charge transfer and lithium-ion diffusion. As a result, Sn2Nb2O7-GO nanocomposite showed enhanced electrochemical performances compared with pure Sn2Nb2O7 and Mixture. As anode material for lithium-ion batteries, the Sn2Nb2O7-GO electrode exhibited a specific capacity of 576.6 mAh g(-1) at 0.1 A g(-1) current density after 100 cycles. What is more, at a higher current density 2 A g(-1), a reversible capacity of about 237.8 mAh g(-1) was achieved.
