Phosphate based composite anode material, preparation method and use thereof
The present invention relates to a novel phosphate based composite anode material, preparation method and uses thereof. Specifically disclosed is a phosphate based composite cell anode material, the material having monoclinic and orthorhombic crystal lattice structures with the chemical formula of A3−xV2−yMY(PO4)3, wherein A is Li+, Na+ or the mixture thereof, M is Mg, Al, Sc, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn or Nb, 0≦x≦3.0, 0≦y≦2.0, and C is the carbon layer. Also disclosed are a preparation method and uses of the composite material. Unlike simple physical mixing, the composite material of the present invention has the advantages of an adjustable electric potential plateau, high reversible capacity, good cycle stability, power consumption early warning and the like.
