  • Patent number: 4347292
    Abstract: The invention relates to an electric cell assembly with an alkaline electrolyte and its current output wires (2, 3) electrically connected to the positive terminal and negative terminal of the electric cell assembly.The metal wire (3) which corresponds to the negative terminal (1) is surrounded, near said terminal and entirely outside the electric cell, with a glass bead (4) which is practically unalterable by the electrolyte.
    Type: Grant
    Filed: June 24, 1981
    Date of Patent: August 31, 1982
    Assignee: Saft-Societe des Accumulateurs Fixes et de Traction
    Inventors: Alain Bernard, Raymond Bonnaterre
  • Patent number: 4166886
    Abstract: A method for precharging the negative electrode of a nickel-cadmium alkaline storage cell whose electrodes are assembled in an at least partially discharged state, wherein before the first charge of the cell, a calculated quantity of a material is introduced in the cell, such material being irreversibly oxidizable in an alkaline medium at a potential such that it is anodically oxidized before nickel hydroxide without evolving any gas, then the cell is charged in the normal way. The material preferably is an organic material of the general formula C.sub.x H.sub.y O.sub.z ; most preferably where x=n, y=2n+2, and z=1, with n less than 4. This particular class of materials comprises the three saturated mono-alcohols: methanol, ethanol and propanol.

  • Patent number: 4125688
    Abstract: The invention relates to a negative electrode for an alkaline electrolyte electric cell. The main electrode material is nickel lanthanide and is characterized by the fact that it also includes a mercury compound. It is applicable to secondary electric cells, in particular of the nickel- or silver-hydrogen type. Cells embodying such negative electrodes exhibit improved capacity irrespective of temperature and electrolyte concentration conditions as compared with like cells in which the mercury compound is not used with the nickel lanthanide.
