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.展开更多
