Abstract

MoO 3 is capable of Li? + insertion/extraction in excess of 6 Li + per formula unit, resulting in a significantly reversible capacity. Recently, chemically modified graphene materials have been used to form hybrid materials with SnO 2, Fe 2O 3, and Mn 3O 4 in attempts to improve electrode capacity and cycling stability. However, an anode combining MoO 3 with graphene has never been reported. MoO 3/graphene composite was prepared through a facile two-step synthesis by homogeneous coprecipitation and subsequent reduction of the graphite oxide with hydrazine. The synergic effect of graphene and MoO 3 improves the electrochemical properties, like cycling performance and rate capability. SEM and TEM images show that MoO 3 uniformly dispersed on the surface of graphene. The synthesis approach presents a promising route to produce large amount of high performance electrode materials for Lithium ion batteries.
