The technology and high-performance industrial equipment for the production of special carbonyl nickel powders for the manufacture of porous bases for electrodes of nickel-cadmium and metal-hydride batteries have been developed. Studies of physical and technological properties of the obtained powders have been carried out and their compliance with the requirements of the battery industry has been shown. Technical specifications were developed for the produced products. Powders are supplied to domestic and foreign battery manufacturers.
The process of carbonyl nickel foam production was developed by engineers of Gipronickel Institute. The technology has the following characteristics: high chemical purity, porosity-95%, various pore diameters (180-200, 300-350 and 450-500 microns), specified surface density and thickness 1-3 mm. Samples of foamed nickel were tested at various Russian battery companies. The test results clearly showed the superiority of batteries based on foamed nickel developed at OAO Gipronickel Institute over batteries using electrolytic foamed nickel. On the basis of the data obtained in the course of various studies, design work was initiated to create an industrial plant for domestic production of carbonyl phenonickel.
Studies on the selection of optimal feedstock for the synthesis of nickel tet-rcarbonyl in the range of carbon monoxide pressures 30-70atm have been carried out.
