Facile fabrication of graphene/Cu6Sn5 nanocomposite as the high performance anode material for lithium ion batteries

- Graphene/Cu6Sn5 nanocomposite is prepared via a facile one-pot method.
- The buffer effects of copper, graphene, and hollow structure are combined.
- This composite delivers excellent long-term (∼1700 cycles) cycling stability.
- High rate (merely 80 s for discharge or charge) capability is obtained.
