Reduced graphene oxide wrapped hollow molybdenum trioxide nanorod for high performance lithium-ion batteries

Reduced graphene oxide wrapped hollow molybdenum trioxide nanorods (MoO3@rGO) have been fabricated by a facile process. The MoO3@rGO 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 Aig after 200 cycles) and excellent rate capability (455 mAh/g at 2 A/g). The excellent electrochemical performance could be attributed as the special core (MoO3)/sheath (rGO) 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. (C) 2017 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
