Porous hollow shell WO3/WS2 nanomaterial and method of preparing same

A method for preparing a WO3/WS2 porous hollow shell nanocrystalline anode material, comprising the steps of:

• 1) adding a hexavalent tungsten salt to a sol A comprising mesocarbon microbeads, and stirring to obtain a sol B, wherein a concentration of the mesocarbon microbeads in the sol A is 0.002˜0.2 g/mL, and a concentration of the W6+in the sol B is 0.01˜2.0 mol/L;
• 2) drying and grinding the sol B obtained by Step 1, and then heating a resulting powder at 200-500° C. for 0.5-2 hours to obtain a porous hollow shell WO3 nanocrystalline material;
• and
• 3) placing the porous hollow shell WO3 nanocrystalline material obtained by Step 2 and a sulfur powder separately into a vacuum tube furnace, controlling such that a degree of vacuum is −0.01 to −0.1 MPa and a temperature is 200-500° C., and reacting for 0.5-3 hours to sulfurize some WO3 of the porous hollow shell WO3 nanocrystalline material into WS2 to obtain a WO3/WS2 porous hollow shell nanocrystalline anode material.
