3D Hollow Sn@Carbon-Graphene Hybrid Material as Promising Anode for Lithium-Ion Batteries
Figure 2
(a) XRD patterns of HSCG and crystalline Sn; (b) typical FESEM and (c and d) TEM images of HSCG. Inset of (d) shows eggs with an egg support, which is similar to HSCG nanostructure where a core-shell Sn@C is supported by planar graphene sheets.
