Abstract:

During hydrometallurgical processing of the oxygen-nickel electrode active materials of the fulfilled alkaline NiMH batteries by crystallization from a solution containing a sulfuric acid, monocrystal nickel sulfate hexahydrate (retgersite) are received. The theoretical substantiation of an opportunity of reception X-ray pure crystal nickel sulfate is resulted.
