Solventless synthesis of an iron-oxide/graphene nanocomposite and its application as an anode in high-rate Li-ion batteries
An iron-oxide/graphene nanocomposite was directly synthesized from an iron-oleate precursor intercalated between graphene layers viaa solventless thermal decomposition method. In the nanocomposite, highly monodisperse gamma -Fe sub(2)O sub(3) nanoparticles were in close contact with graphene, and th...

Summary: | An iron-oxide/graphene nanocomposite was directly synthesized from an iron-oleate precursor intercalated between graphene layers viaa solventless thermal decomposition method. In the nanocomposite, highly monodisperse gamma -Fe sub(2)O sub(3) nanoparticles were in close contact with graphene, and they acted as mutual spacers in the nanocomposite to prevent aggregation of the nanoparticles and restacking of the graphene layers. The iron-oxide/graphene nanocomposite shows outstanding electrochemical performance, including high reversible charge/discharge capacity, good cycling stability, and remarkable high-rate-performance (500 mA h g super(-1) at 5000 mA g super(-1)) when it was employed as a lithium ion battery anode. This nanocomposite can be a potentially valuable candidate anode material for high-rate Li-ion batteries. |
