FIELD: lithium-ion batteries.
SUBSTANCE: invention relates to technologies for producing a positive electrode of lithium-ion batteries (LIB) and can be used in the production of LIB. A method for producing a lithium-ion battery cathode includes obtaining a mixture of carbon nanotubes obtained by gas-phase chemical deposition on a Co-Mo/Al2O3-MgO catalytic system and treating them with an ozone-oxygen mixture, FSN-4 graphite and LA 132 rubber adhesive, which is 15 % water-based emulsion, followed by mixing and application to the collector, drying and rolling, and as additional components, the mixture contains a fluoroplastic emulsion and SuperP carbon material.
EFFECT: increase in the specific capacity of the cathode over 200 mAh/g.
