Ni3V2O8 is a promising anode material for Li-ion batteries due to its high theoretical capacity that originates from the multivalence of nickel and vanadium. However, its low conductivity results in poor rate performance, and the large volume variation leads to poor stability induced by the inevitable pulverization and aggregation of active materials during cycling. To address these issues, a strategy by anchoring ultrafine Ni3V2O8 nanoparticles on reduced graphene oxide with hierarchical architecture (rGO@Ni3V2O8) is presented. This method is shown to effectively facilitate charge transfer, maintain structural integrity, and accommodate the volume variation during cycling. As a result, the rGO@Ni3V2O8 composite manifests a very stable and high reversible capacity of 1050 mA h g(-1) over 200 cycles at a current density of 500 and 900 mA h g(-1) after the subsequent 200 cycles at 1 A g(-1). Furthermore, excellent rate capability is achieved. More than 45% of the capacity can be retained when the current density is increased from 0.1 to 10 A g(-1).
