Intercalated SiOC/graphene composites had been prepared by thermal reduction of TTCS/GO mixture, which was fabricated by dispersing GO into TTCS. Transmission electron microscopy (TEM) showed that SiOC nanoparticles were well encapsulated in a graphene matrix. The 10SiOC/graphene anode maintained a reversible capacity of 582mAh/g after 90cycles and had an initial coulombic efficiency of 63%. The excellent cycling stability is attributed to the fact that the SiOC/graphene composite can accommodate large volume change of SiOC and maintain good electronic contact. These results indicate that SiOC/graphene is an excellent anode material and has promising prospects in lithium ion batteries (LIBS) applications.
