Abstract
The invention relates to a method for producing a lithium-ion cell in which a polymer layer is applied to an aluminum foil, a nickel-containing cathode slurry is applied to the aluminum foil, the polymer layer is chemically and mechanically stable during this electrode production, and the moist cathode slurry is dried. The method is improved particularly in terms of cost and environmental protection in that water is used as the solvent for the cathode slurry and that the polymer layer is dissolved during the formation of the lithium-ion cell.
