METHOD TO PRODUCE COMPOSITE NiO/C MATERIAL Russian patent published in 2012 - IPC H01M4/52 C01G53/04 B05D5/12 B82B3/00 

FIELD: power engineering.

SUBSTANCE: method to produce a composite NiO/C material containing 15-60% NiO and representing crystallites β-NiO evenly distributed on a carbon carrier surface with the average size of 2-5 nm, is based on production of NiO nanoparticles as a result of electrochemical oxidation and destruction of two nickel electrodes in solutions of alkaline metal hydroxides with concentration of 2 mole/l under action of AC current with frequency of 50 Hz at average value of current referred to a unit of electrode surface area making 0.3-1.5 A/cm², with simultaneous deposition of produced nickel oxide nanoparticles onto the carbon carrier, subsequent filtration of the produced suspension, washing of composite by distilled water and its drying at 80°C for 1 hour.

EFFECT: invention makes it possible to increase quality of produced material due to absence of admixtures and to reduce costs for its production.
