Additives for lubricating agents used in the lamination of lithium sheets into thin films

These additives are represented by the following general formula:

Additives for lubricating agents used in the lamination of lithium

Additives are represented by the following general formula:

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.
