ABSTRACT:
A relatively little adherent and fragile powdery layer is deposited on a continuous metallic tape or strip by passing continuously said tape negatively polarized through an electrolytic bath contained in a vat and containing ions of the active metal to be deposited; in the bath is immersed an electrode made out of active metal and a compensation electrode; the powdery layer is consolidated by means of a calender.
Said process is applicable to the manufacture of cadmium or zinc negative electrodes for electrochemical generators.
