Fabrication and enhanced electrochemical performances of Mo03/graphene composite as anode material for lithium-ion batteries

Molybdenum trioxide (MoO3)/graphene composite were prepared by integrating MoO3 and graphene in dimethylformamide (DMF). The morphology and structure of the materials were characterized by X-ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. The electrochemical properties of MoO3/graphene composite with different ratios were studied as anode materials for lithium-ion batteries using galvanostatic charge-discharge and cyclic voltammetry. We observed that the MoO3/graphene anode with a weight ratio of 1:1 (MoO3:graphene) exhibits a high lithium storage capacity of 967 mA h g -1 at the current density of 500 mA g, satisfactory cycling stability and good rate capability.
