Carbon microsphere/porous vanadium oxide composite material as well as preparation method and application thereof

The invention belongs to the field of nano materials and electrochemical devices, and discloses a carbon microsphere/porous vanadium oxide composite material, carbon microspheres in the composite material are located on the surface and in pores of porous vanadium oxide, the diameter of the carbon microspheres is 1-2 microns, and the diameter of the porous vanadium oxide is 1-2 microns. The pores of the porous vanadium oxide are formed by interweaving irregular flexible bent strip-shaped vanadium oxides, and the pore diameter is 20nm-2mu m. Due to the porous structure of the composite material, the flexible bending of the strip-shaped vanadium oxide, the attachment of the carbon microspheres on the surface of the porous vanadium oxide, the filling among pores and other characteristics, the composite material has excellent electrochemical performance, and can be used for lithium ion battery electrode materials or other electrochemical device materials. 本发明属于纳米材料与电化学器件领域，公开了一种碳微球/多孔钒氧化物复合材料，所述复合材料中碳微球位于多孔钒氧化物的表面
