摘要：

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. © 2015 WILEY-VCH Verlag GmbH & Co.
