Three-dimensional hollow WS2/C composite electrode material and preparation method and application thereof

The invention discloses a three-dimensional hollow WS2/C composite electrode material and a preparation method and application thereof, a three-dimensional hollow carbon structure is constructed by using a hard template method and ZIF-8 derived carbon, and then the three-dimensional hollow WS2/C composite material is synthesized by using a solvothermal method. The WS2/C composite electrode material prepared by the method is high in phase purity and free of other impure phases; the WS2/C composite electrode material is of a three-dimensional hollow composite structure, and the prepared WS2/C composite electrode material is good in dispersity and uniform in size distribution; when the WS2/C composite electrode material is applied to the sodium ion battery, the three-dimensional hollow structure can effectively improve the volume expansion of the electrode in the charge-discharge process on one hand, and the three-dimensional hollow carbon layer structure and the nano structure can ensure the high-speed migratio
