We present a novel strategy to prepare MnCo2O4/graphene composites on nickel foam. TEM analysis reveals that high density of MnCo2O4 nanoparticles of similar to 5-10 nm are uniformly anchored on graphene nanosheets. The MnCo2O4/graphene-anchored Ni foams are used as binder -free integrated anodes for lithium ion batteries (LIBs) and exhibit superior lithium -storage performance. The MnCo2O4/graphene composites exhibit high cycling stability (868 mAh/g at 100 mA/g) and good rate capacity (607 mAh/g at 1.6 A/g) as anode materials for LIBs. The prominent electrochemical performance is associated with the synergistic effects of 3D porous Ni foam and graphene, which promote electron transfer and buffer the large volume fluctuation of metal oxides during the lithiation/delithiation progress.
