Porous SnO2@C/graphene nanocomposite with 3D carbon conductive network as a superior anode material for lithium-ion batteries

- Porous nano-sized SnO2@C/graphene electrode material was designed and prepared.
- It has a 3D carbon conductive network consisted of graphene sheets and carbon shell.
- The carbon shell can suppress the aggregation of nanoparticles and undesired reactions.
- It exhibits high reversible capacity, outstanding cyclability and good rate capability.
