SiO/ reduced graphene oxide (SiO/rGO) composite was prepared by a simple hydrothermal process involving the capsulation of SiO particles with graphene hydrogel followed by the HF treatment. The prepared composite electrode exhibited higher discharge capacity and better rate capability than the pristine SiO electrode. Such enchancement could be attributed to the efficient conducting/buffering rGO matrix and the successful corrosion of SiO2 shell on the surface of SiO. (C) 2014 Elsevier Ltd. All rights reserved.
