FIELD: chemistry.
SUBSTANCE: invention relates to chemical industry and can be used produce cathode material in lithium ion batteries. The method includes mixing lithium nitrate and cobalt (II) nitrate solutions in molar ratio of 1:1 while adding pyridine nitrate, taken in molar ratio of lithium nitrate to amine nitrate of 1:3, at 20-25°C for 20-30 minutes. Water is evaporated to obtain a dry product which is annealed at 400-450°C for1-2 hours.
EFFECT: invention enables to obtain fine lithium cobaltite while enabling control of the particle size of the end product.
