Preparation of SnO2-Nanocrystal/Graphene-Nanosheets Composites and Their Lithium Storage Ability

摘要: To improve the performance of SnO2 as anode materials for lithium battery, a facile and efficient method to prepare composites SnO2-nanocrystal/graphene-nanosheets was developed on basis reduction graphene oxide (GO) by Sn2+ ion. Changing ratio GO led morphology changes SnO2/graphene-nanosheets composite. The battery studied in this report. results showed that electrochemical greatly enhanced, indicating might have promising future application Li-ion battery.
