ELECTRODE MATERIAL BASED ON ACTIVATED CARBON, ELECTRODE FOR CAPACITIVE DEIONISATION OF WATER AND METHOD OF THEIR PRODUCTION Russian patent published in 2024 - IPC H01M4/96 C02F1/469 

FIELD: electricity; various technological processes.

SUBSTANCE: electrode material based on activated carbon, an electrode for capacitive deionisation of water and a method of making said electrodes relate to devices and materials for capacitive deionisation of water. Electrode material for a capacitive water deionisation electrode according to the claimed invention contains activated carbon, carbon nanotubes and cellulose. Electrode for capacitive deionisation of water has a layer of active electrode material and two layers-current collectors made in the form of two layers of carbon-graphite fabric on both sides of the layer of active electrode material. Method of making a capacitive water deionisation electrode includes preparing a cellulose solution in an aqueous solution of an ethylenediamine complex of copper, mixing the cellulose solution with activated carbon powder and carbon nanotubes, forming the obtained paste-like mixture in the form of a layer between two layers of carbon-graphite fabric, hardening the cellulose in a bath with an acid solution or acid vapour, washing with water and (optionally) drying.

EFFECT: proposed invention can be used in capacitive water deionisation apparatuses.
