摘 要:Reduced graphene oxide wrapped hollow molybdenum trioxide nanorods (MoO3@rGO) have been fabricated by a facile process. The MoO3@rCO shows improved lithium storage performance. It could deliver a high reversible capacity (842 mAh/g at 0.1 A/g), excellent cycling stability (778 mAh/g at 0.1 A/g after 200 cycles) and excellent rate capability (455 mAh/g at 2A/g). The excellent electrochemical performance could be attributed as the special core (MoO3)/sheath (rCO) structure, which could accommodate the volume change of MoO3 during lithiation/delithiation process. In addition, the rGO coating layer could improve the electronic conductivity of MOO3.
