NiMoO 4 /Reduced graphene oxide (NiMoO 4 /rGO) composites material was prepared by a hydrothermal method. When used as a anode material for lithium-ion batteries, the NiMoO 4 /rGO composites show superior rate capability and excellent cycling stability. A reversible capacity of approximately 808 mAh g – 1 is retained even after 100 cycles at 100 mA g – 1. It is believed that the surface modification by graphene nanosheets contribute to the improved kinetics of lithium-ion diffusion, excellent structural stability and superior electrochemical performance.
