Utilization of lamellar nickel-oxide electrodes

The paper suggests a new way of more effective use of nickel in the production of alkaline cells with pocket-plate oxide-nickcl electrodes which also helps reduce pollution of the environment.
To get the desired effect you should separate the metal part of the electrode from the anode material by deforming pocket-plate oxide- nickel electrodes at the pressure of 19-45 H/mm2 during 0.5-1 second, then extract and leach anode material with sulphuric acid solution (its strength is 200-300 g/1) at 60-80°C till ion concentration reaches Ni2+ 65-110 g/l and pH = 3.5-5.
