FIELD: electrical engineering; industrial production of anodic masses for alkali nickel-cadmium batteries.
SUBSTANCE: proposed method used in production of alkali batteries with oxide-nickel plate electrodes involves separation of metal component from anodic mass by deforming oxide-nickel plate electrodes at pressure of 19 - 45 N/mm2 for 0.5 - 1 s, sieving, and magnetic separation, followed by leaching of anodic mass with sulfuric acid solution of 200 - 300 g/l concentration to ion content Ni 65 110 g/l at temperature of 60 - 80 °C to pH = 3.5 - 5.
EFFECT: enhanced efficiency of nickel use in battery manufacture, reduced pollution of environment.
