Title: Process for the manufacture of electrodes

Abstract: A process for the manufacture of electrodes suitable for electrolytic cells which comprises impregnating a porous matrix structure consisting of an electrode metal with an oxide or hydroxide of the metal by galvanic activation in a bath containing a salt of the metal, in neutral to acid solution, in which at least two porous metal matrix electrodes are placed into the bath and both are impregnated at the same time by applying one terminal of a direct voltage to each electrode and reversing the polarity of the direct voltage at a pulsating frequency. The invention is particularly applicable to the production of positive nickel electrodes.
