CARBON NANOTUBE DISPERSION, DISPERSION PREPARATION METHOD, CATHODE PASTE, CATHODE PRODUCTION METHOD AND CATHODE Russian patent published in 2022 - IPC H01M4/13 H01M10/525 C01B32/158 

FIELD: cathode manufacturing.

SUBSTANCE: inventions group relates to a method for preparing a dispersion of single-walled and/or double-walled carbon nanotubes and their agglomerates, a method for preparing a cathode paste, a cathode paste, a method for manufacturing a cathode and a cathode. The dispersion contains a solvent, most of whose molecules are electrically neutral, hydrogenated nitrile butadiene rubber and single-walled and/or double-walled carbon nanotubes in an amount of 0.2 to 2 wt.% and the mass ratio of single-walled and/or double-walled carbon nanotubes to hydrogenated nitrile rubber is not less than 0.1 and not more than 10.

EFFECT: high stability during storage and transportation and at the same time low viscosity in various technological processes.
