Abstract: The invention relates to a method for providing an electrode foil for producing a lithium-ion rechargeable battery, in which a metal foil is provided with a coating of electrode material and in which the coating of electrode material is plasma treated. The coating of electrode material is plasma-treated by the coating being subjected to an atmospheric plasma jet. The invention also relates to a method for producing a lithium-ion rechargeable battery, in which a first electrode foil for the negative electrode and a second electrode foil for the positive electrode are provided, in which the first and second electrode foils are arranged one above the other with a separator layer in between to form a foil stack and in which the foil stack is impregnated with a liquid electrolyte. The first and/or the second electrode foil is/are provided by the aforementioned method.
