摘要：
The hierarchical MoO2@RGO composite was synthesized through a simple ethanol thermal reduction combined with an annealing process. This unique one-step design for hybridizing hierarchical porous MoO2 spheres with reduced graphene oxide (RGO) sheet is different from that of MoO2/graphene composites reported previously. The resultant hierarchical MoO2@RGO electrode was applied as an anode material for lithium-ion batteries and found to exhibit outstanding electrochemical performance with a reversible capacity of 708 mAh g(-1) at a current density of 0.5 A g(-1) after 50 cycles. Even when cycled at 2 A g(-1), it still maintained a decent capacity of 473 mAh g(-1). (C) 2017 Elsevier B.V. All rights reserved.
