titleOfInvention | Pyrophosphate composite material, preparation method and application thereof, and sodium ion battery |
abstract | The invention relates to the technical field of sodium ion batteries, and particularly discloses a pyrophosphate composite material, a preparation method and application thereof, and a sodium ion battery. The pyrophosphate composite material has a core-shell structure: wherein the core part comprises sodium vanadium pyrophosphate and graphene, the sodium vanadium pyrophosphate is in a spherical or sphere-like structure and has a porous structure, and the graphene is filled in the porous structure; the shell part is a graphene layer coated on the surface of the vanadium pyrophosphate; the content of the graphene and the graphene layer in the pyrophosphate composite material is 1.0-10 wt.%. The pyrophosphate composite material provided by the invention has good sodium ion diffusion characteristics, and when the pyrophosphate composite material is used as a positive electrode active material or a negative electrode active material of a sodium ion battery, the sodium ion battery has high reversible specific capacity, good cycle stability and rate characteristics. |
