  • Additives for lubricating agents used in the lamination of lithium sheets into thin films
    Patent number: 6517590
    Abstract: These additives are represented by the following general formula: L—Y—S in which L designates a hydrocarbon radical which serves as lubricating segment; S designates an oligomer segment which serves as solvating segment of metallic salts and Y designates a chemical bond which joins the hydrocarbon radical and the oligomer segment. With these additives there is no more need to subsequently wash the surface of laminated lithium.
    Type: Grant
    Filed: January 11, 2000
    Date of Patent: February 11, 2003
    Assignee: Hydro-Quebec
    Inventors: Michel Gauthier, Patrick Bouchard, Paul-Emile Guerin, Michel Armand
  • Additives for lubricating agents used in the lamination of lithium sheets into thin films
    Patent number: 6019801
    Abstract: These additives are represented by the following general formula:L--Y--Sin which L designates a hydrocarbon radical which serves as lubricating segment; S designates an oligomer segment which serves as solvating segment of metallic salts and Y designates a chemical bond which joins the hydrocarbon radical and the oligomer segment. With these additives there is no more need to subsequently wash the surface of laminated lithium.

  • Process for laminating a thin film of lihium by controlled detachment
    Patent number: 5528920
    Abstract: A film of lithium capable for example of providing the anode of a polymer electrolyte battery is produced by laminating a lithium sheet between two working rolls. At the outlet, the film remains attached to one of the two rolls up to a given point of the circumference of the latter where it forms an angle of about 90.degree. with the meeting point between the two rollers. A sufficient tension is thereafter exerted on the film, which in any case is inferior to the limit of elasticity of lithium, by pulling the film in order to detach it from the surface of the roller and usually so that the given point moves into an intermediate position between 90.degree. and the meeting point, for example about 45.degree.. The product obtained may also be used any time there is a need for a film of lithium having a thickness for example between 10 and 100 .mu.m.
