FIELD: electrical engineering.
SUBSTANCE: result is achieved due to increase in homogeneity of electrode active mass and increase of lithium diffusion coefficient; for this purpose in the suggested method active mass is mixed with electroconductive additive, the received mass is saturated with solution of polymer electrolyte, cathode mass is dried and grinded in ball crusher and press-fitted to current tap; at that after drying cathode mass is treated additionally in plastic yield process at torsion under pressure of at least 1.7 GPa and relative strain of 22-24.
EFFECT: improvement of technological effectiveness in cathode manufacturing process with increase of its discharge capacity.
