An ordered hollow MoS2 nanocages/RGO nanocomposite is constructed by a simple solvothermal-assisted assembly method combined with freeze-drying and annealing.In this novel nanostructure,hollow MoS2 nanocages are homogeneously distributed on graphene sheets with a tight bond of C-O-Mo.The nanosized and hollow MoS2 nanocages can effectively accommodate the huge volume change during charge/discharge process and increase the number of electrochemical reaction active sites,accelerating the kinetics of lithiation/delithiation.The tight C-O-Mo bond between graphene and MoS2 further reinforces the structural stability,thus improve the electrical conductivity and substantially enhance the lithium storage performance of MoS2 anode material.As a result,this novel nanocomposite shows a long-cycle stability of 717.4 mAh·g-1 after 800 cycles at a high current density of 3 A·g-1,exhibiting great potential as an anode nanocomposite for advanced lithium-ion batteries.
