Zusammenfassung:Process for the manufacture of positive electrodes for alkaline electrical accumulators, the electrodes of which comprise a porous substrate made of nickel or of a nickel-plated material, which serves as support to an active material based on nickel hydroxide, being said active material applied over the support in two successive stages ; a first main phase of mechanical pasting, during which most of the active material is applied, and a second complementary phase of electrochemical impregnation.
