METHOD FOR PRODUCING CATHODE ACTIVE MATERIAL FOR LITHIUM BATTERIES

摘要

The invention relates to chemical current sources and can be used for producing lithium batteries. The essence of said invention lies in that an iron-sulphide mixture is produced by electrolyse from an aqueous solution of iron, nickel and copper sulphate and sodium thiosulphate to which sodium molibdate of a concentration ranging from 2.5 to 3 g/l is added at the following component ratio: 7-10 g/l FeSO4; 1.5-1.55 g/l NiSO4; 0.5-0.55 g/l Cu SO4; 2.5-3.0 g/l Na2MoO42H2O; 5.0-5.5 g/l Na2S2O35H2O. Said invention increases the cycling capacity of a cathode active material in regular conditions, thereby making it possible the use thereof for low-temperature batteries.
