  • Process for making negative electrodes for electrochemical generators, and the negative electrodes thus obtained
    Patent number: 4180441
    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.
    Type: Grant
    Filed: May 23, 1978
    Date of Patent: December 25, 1979
    Assignee: Societe les Piles Wonder
    Inventors: Bernard Stiker, Fernand Jolas
