Abstract：

Embedded　Si/graphene　composite　was　fabricated　by　a　novel　method,　which　was　in　situ　generated　SiO2　particles　on　graphene　sheets　followed　by　magnesium-thermal　reduction.　The　tetraethyl　orthosilicate　(TEOS)　and　flake　graphite　was　used　as　original　materials.　On　the　one　hand,　the　unique　structure　of　as-obtained　composite　accommodated　the　large　volume　change　to　some　extent.　Simultaneously,　it　enhanced　electronic　conductivity　during　Li-ion　insertion/extraction.　The　MR-Si/G　composite　is　used　as　the　anode　material　for　lithium　ion　batteries,　which　shows　high　reversible　capacity　and　ascendant　cycling　stability　reach　to　950　mAh·g−1　at　a　current　density　of　50 mA·g−1　after　60 cycles.　These　may　be　conducive　to　the　further　advancement　of　Si-based　composite　anode　design.　©　2017,　The　Author(s).
