METHOD OF PRODUCING CATHODE MATERIAL WITH OLIVINE STRUCTURE FOR LITHIUM SELF-CONTAINED POWER GENERATION Russian patent published in 2013 - IPC H01M4/04

Abstract RU 2482572 C2

FIELD: chemistry.

SUBSTANCE: invention can be used to produce cathode materials with an olivine structure for lithium self-contained power generation (hybrid transport, electric cars, buffer systems for energy storage etc). The method involves mixing a lithium salt Li₂CO₃, iron (III) oxide Fe₂O₃, citric acid and ammonium dihydrophosphate in stoichiometric ratio. Particles of the mixture are ground in ball mill in acetone medium and subsequent heat treatment is carried out at temperature of 350°C-650°C.

EFFECT: invention increases specific capacity and stability during cycling.
