A composite of graphene-cuprous oxide (Cu{sub 2}O) was prepared using copper acetate-adsorbed graphene oxide (GO) sheets as precursors. In this composite, in-situ formed Cu{sub 2}O particles were derived from the adsorbed copper acetate which attached to graphene sheets and prevented the aggregation of the reduced graphene oxide sheets. The as-synthesized Cu{sub 2}O crystals were cube-like particles distributed randomly on the sheets due to the template effect of GO, consequently forming a graphene-Cu{sub 2}O cubes composite. A preliminary study on the electrochemical behavior of the graphene-Cu{sub 2}O composite used as anode material for lithium ion batteries was carried out. - Abstract: The graphene oxide sheets are reduced and almost exfoliated due to the in-situ formation of Cu{sub 2}O crystals deriving from the adsorbed copper acetate.
