FIELD: electric elements.
SUBSTANCE: invention relates to a method for producing a cathode of a lithium-ion accumulator, particularly, to a method for producing precursor particles without using organic chelating additives for changing the deposition rate, to a method for producing active cathode particles therefrom, and to a precursor particle produced by such a method. In the method, by supplying various types of anionic compositions and/or cationic compositions and adjusting the pH in accordance with the substance, the particles are deposited forming a suspension, the suspension is separated, treated with water and dried resulting in a cathode particle precursor, the cathode particle precursor is mixed with a lithium source and calcined resulting in a core-shell structure of active cathode particles.
EFFECT: increased electrochemical characteristics, reduced corrosion.
