FIELD: chemistry.SUBSTANCE: invention relates to an active material based on carbon-coated lithiated vanadium phosphate for use in the positive active mass of lithium ion batteries. Lithiated vanadium phosphate crystals are further modified with a Nacation on the lithium sublattice, one or more cations from a group comprising Mg, Al, Yand Laon the vanadium sublattice, and with a For Clanion on the phosphate sublattice, and are a compound of formula LiNaVM(PO)Hal/C, where M is one or more metals from a group comprising Mg, Al, Y, La; Hal = F, Cl; 0 < x ? 0.1; 0 < y ? 0.2; 0 < z ? 0.16.EFFECT: obtaining an active material for use in the positive active mass of lithium ion batteries with high capacitance and power, as well as acceptable cycling stability.3 dwg |
