  • Zinc electrode
    Patent number: 4358390
    Abstract: A zinc electrode comprising at least one active portion is improved due to the fact that the active portion has an open porosity of at least 60% and comprises electron-conductive fibers and due to the fact that the active material or materials are distributed practically uniformly throughout the active portion.
    Type: Grant
    Filed: December 8, 1980
    Date of Patent: November 9, 1982
    Assignee: Compagnie Generale des Etablissements Michelin
    Inventors: Alain Coulombeau, Georges Peyron

  • Process for assembling a porous membrane on a support and assembly produced in this manner
    Patent number: 4261801
    Abstract: Process for the assembling at least one support, at least part of the surface of which conducts electrons, with at least one electrically insulating membrane, said membrane having pores at least part of which are open pores, is improved by causing an electrolytic depositing of at least one metal in a part of the open pores, said electrolytic deposit adhering to at least a part of the electron-conductive surface of the support.

  • Electrochemical device with solid separator and solid electrolyte
    Patent number: 4216273
    Abstract: Electrochemical device comprises a negative compartment and a positive compartment. The negative compartment contains a negative medium formed at least in part of a liquid metal, and the negative and positive compartments are separated by a solid separator which is capable of being traversed by ions of the metal and is a conductor of said ions. The device is characterized by the fact that the negative compartment contains a solid electrolyte which is a conductor of these ions, this electrolyte separating the negative compartment into two regions--on the one hand, a negative region containing the negative medium and a negative collector, and, on the other hand, an intermediate region, located between the separator and the electrolyte, containing an intermediate medium formed at least in part of the metal in liquid state and/or of at least one salt of the metal in dissolved or molten state.
