COMPOSITE CATHODIC MATERIAL OF LITHIUM ION BATTERY BASED ON LIV(PO)WITH NASIKON STRUCTURE AND METHOD OF ITS OBTAINING Russian patent published in 2015 - IPC H01M4/48 H01M4/58

Abstract RU 2542721 C1

FIELD: electricity.

SUBSTANCE: method comprises mixing of the lithium salt Li₂CO₃, vanadium oxide (V) V₂O₅, ammonium dihydrogen phosphate NH₄H₂PO₄in a stoichiometric ratio, and also starch (C₆H₁₀O₅) as a reducer and a precursor of carbon component, and crushing of particles of the mix is performed in a spherical mill in the acetone medium with the subsequent heat treatment at the temperature 750-850°C.

EFFECT: invention allows to obtain the composite material ensuring increase of specific capacity, charging current of Lithium ion battery, provides its stability when cycling.
