Molybdenum Disulphide-graphene Nanosheets Composite as a High-performance Anode with Good Cycling Stability for Lithium-ion Batteries
Two-dimensional(2D)molybdenum disulphide(MoS2)offers high theoretical lithium storage capacity of 670 mAh g-1 with graphite-like structure.However,the material suffers from fast capacity fading,restricts its application in lithium-ion batteries.To improve cycling stability,a robust nanocomposite architecture of MoS2-graphene is achieved by hybridization of bulk graphite and MoS2.A large-scale high-energy ball milling process is developed for the first time to construct MoS2-graphene nanosheets hybrid structure in which both MoS2 and graphite are well embedded and uniformly dispersed in a nanometre level.The MoS2-graphene composite anode exhibits excellent cycling stability with high reversible capacity of 553 mAh g-1(98%retention)at 250 mA g-1 after 100 cycles which is significantly higher than that of MoS2 electrode(37 mAh g-1).Therefore,our material preparation approach can potentially be used for the production of composite nanosheets in large quantity for a wide range of applications.
