To improve the performance of SnO 2 as anode materials for lithium battery, a facile and efficient method to prepare the composites of SnO 2 -nanocrystal/graphene-nanosheets was developed on the basis of the reduction of graphene oxide (GO) by Sn 2+ ion. Changing the ratio of Sn 2+ and GO led to the morphology changes of SnO 2 /graphene-nanosheets composite. The performance as anode materials for lithium battery was studied in this report. The results showed that the electrochemical performance of composites was greatly enhanced, indicating that the composites might have a promising future as application in Li-ion battery.
