METHOD OF MANUFACTURE OF NEGATIVE ELECTRODE OF LITHIUM-ION BATTERY Russian patent published in 2018 - IPC H01M10/52 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used in the manufacture of negative electrodes of lithium-ion batteries. Manufacturing method consists in joining a metal, predominantly copper, substrate (for current collection) and a slurry of a silicon material. Electrode material contains copper and silicon microparticles and nanoparticles. They are formed simultaneously in the form of a thickness layer of 10–50 mcm galvanically from the electrolyte on a smooth substrate from which the resulting composite electrode is removed.

EFFECT: invention allows to increase the capacity of the battery, due to the increase in the surface area of silicon per unit surface.
