3D graphene–silicon (G–Si) network is successfully achieved by employing commercial sponge as a template and graphene oxide as a building block, and subsequent magnesium thermal reduction. The unique textural features of the 3D G–Si network including porous structure, good flexibility, high electrical conductivity, and ultrathin hybrid walls lead to the superior electrochemical performances for lithium storage.
