METHOD OF PRODUCING NANOCOMPOSITE MATERIAL OF COMPOSITION CARBON MATRIX - NICKEL COBALTATE Russian patent published in 2024 - IPC H01G9/00 H01G11/36 

FIELD: various technological processes.

SUBSTANCE: invention relates to production of nanocomposite materials based on active components deposited on a carbon base. It can be used in electrode industry for making electrodes in ionistors. Disclosed is a method of producing a nanocomposite material of the composition carbon matrix – nickel cobaltate, which is carried out by successive impregnation of the carbon matrix with a mixture of aqueous solutions of cobalt and nickel chlorides, as well as a solution of a precipitant – sodium azide, followed by removal of the solvent and thermal treatment. Used carbon matrix is multi-wall carbon nanotubes with total specific surface area of about 250 m²/g, outer diameter of tubes about 10-20 nm and inner diameter of 6-10 nm. Particles obtained as a result of thermal decomposition are nanosized crystals of nickel cobaltate NiCo₂O₄ with an average size of 5-10 nm.

EFFECT: simplification of the technological process of manufacturing nanostructured composite material, increase in the specific capacity of the electrode material.
