Hydrophobic dispersion-derived Si/rGO nanocomposites in SiOC ceramic matrix as anode materials for high performance lithium-ion batteries

A Si/rGO/SiOC composite is designed using hydrophobic rGO for uniform distribution of Si in SiOC matrix. rGO contributed to the improvement of electrical conductivity, and the volume expansion of Si was effectively alleviated by the SiOC material.
