FIELD: electricity.
SUBSTANCE: in manufacturing method of lithium-ferrum phosphate, which consists in the fact that iron oxide is mixed with ammonium dihydrogen phosphate and lithium hydroxide on dry basis with further mechanical activation and two-stage heat treatment at temperature of 400°C during 4 hours, at temperature of 600°C during 4 hours, according to invention at the first stage iron oxide is mixed with ammonium dihydrogen phosphate and lithium hydroxide is added during plastic flow at torsion at pressure of not less than 2.0 GPa and relative deformation values of 20-22.
EFFECT: simplifying the process for obtaining lithium-iron phosphate, improving its degree of dispersion, capacity and service life of cathodes on its basis.
