METHOD OF PRODUCING CATHODE MATERIAL OF COMPOSITION NaVO(PO)F (where 0<X≤1) FOR Na-ION BATTERIES Russian patent published in 2019 - IPC H01M4/58 H01M4/1397 H01M10/54 C01B25/45 C01B25/455 C01B9/08 C01D13/00 C01G31/00 B01J19/12 B82B3/00 B82Y30/00

Abstract RU 2704186 C1

FIELD: chemistry.

SUBSTANCE: invention can be used in making Na-ion batteries. Method of producing cathode material containing Na₃V₂O_2x(PO₄)₂F_3-2x (0<x≤1), includes reaction on a reaction mixture containing vanadium oxide V₂O₅, ammonium dihydrophosphate NH₄H₂PO₄, sodium fluoride NaF, a reducer of vanadium cations V⁺⁵ and water by microwave radiation.

EFFECT: invention enables to obtain a single-phase compound for a cathode of a Na-ion battery with high crystallinity at low temperature and short synthesis time.
