Abstract

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.
