ELECTRODEPOSITION OF NICKEL IN AN ACIDIC MEDIUM FROM POWDER OF BATTERIES MADE OF NICKEL METAL HYDRIDE (NiMH)
This piece of work is focused on the evaluation of an alternate route to recover Nickel from NMH residual batteries beginning from the mechanical stage of disassembly, fragmentation and conditioning of powders by means of the process of mechanofusion and the stage of extraction of nickel from acidic electro deposition. By means of the process of mechanofusion, the properties of the particles are modified with a view to increasing the efficiency of the electrolytic treatment via the size control, particle form and the dispersion of species on a particle bed. The obtaining of metallic nickel was made at 50 mA/m2 at a temperature of 21°C via electrolysis with a constant potential producing a deposit of 295 Ni.
