▎ 摘  要

An electrode based on hollow MoS2 spheres intercalated graphene film was firstly fabricated. When used as an electrode in a supercapacitor, the unique structure can provide electrically conducting channels to promote electrolyte penetration and utilize their surface as much as possible. Thus, the resultant binder-free electrode demonstrated a high specific capacity of 286.8 F g(-1) more than 2 times of pure MoS2 hollow spheres (116.4 F g(-1)). A supercapacitor based on MoS2/grapheme and active carbon can achieve a maximum energy density of 22.0 W h k(-1) at 800 W kg(-1). The outstanding electrochemical properties of the hybrid electrode demonstrate that it holds great potential for the next-generation energy storage applications.
