Abstract
Graphene-based nanocomposites have been demonstrated to be promising high-capacity anodes for lithium ion batteries to satisfy the ever growing demands for higher capacity, longer cycle life and better high-rate performance. In this study, graphene-metal based anode materials which have high mechanical, electrochemical, electrical and thermal properties, were synthesized. To synthesize graphene-based composite anode materials, primarily bulk graphite was oxidized by using modified Hummers method and then graphite oxide was reduced to nano graphene material through thermal exfoliation method. By virtue of this technique, from bulk graphite good quality graphene in high quantities were obtained. Finally, nano metal particles Tin (Sn) and Molybdenum disulfide (MoS2) were added into the graphene nano structure to produce graphene-metal hybrid material. Structural characterization of the obtained samples were characterized by surface electron microscope (SEM), X-Ray Diffraction (XRD) and Raman Spectroscopy. Also electrochemical performance of the prepared composite samples were analyzed in coin cell.
