AUXILIARY BATTERY WITH NON-AQUEOUS ELECTROLYTE AND METHOD OF MANUFACTURING THE AUXILIARY BATTERY WITH NON-AQUEOUS ELECTROLYTE Russian patent published in 2018 - IPC H01M4/04 H01M10/52 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, namely to a method of production a lithium battery with a non-aqueous electrolyte, in which the ablation of the transition metal from the active material of the positive electrode is prevented. Method includes: manufacturer (S101) of the plate (140) to the positive electrode through the formation of a layer (142) of the active material of positive electrode, which contains trilithium phosphate, on foil paper (141) of the collector of the current positive electrode; placing (S102) of the positive electrode plate (140), a negative electrode plate (150) and an electrolytic bath (120) in the battery jar; and charging (S103) of the battery after assembly. In the manufacture of the positive electrode plate, the active material (170) of the positive electrode is a complex oxide that includes, at least, lithium and manganese. In the production of the positive electrode plate, the conductive additive (180) is produced by attaching at least, manganese or manganese oxide to the surface of the carbon material.

EFFECT: increase in the working time of the active material of the positive electrode, and also the prevention of the oxidative decomposition of the non-aqueous electrolytic solution is the technical result of the invention.
