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. {URL}: https://www.sciopen.com/article/10.1007/s12274-020-2739-3 {Language}: en
