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.

Abstract: A nozzle assembly for generating an atmospheric plasma jet includes an inlet, through which the jet can be introduced into the nozzle assembly, and a channel connected to the inlet so that the plasma jet introduced is conducted through the channel. Multiple nozzle openings are provided in the channel wall along the channel, through which a plasma jet can exit the assembly. The cross section of the channel in the region of a nozzle opening is shaped in such a way that a virtual medial plane runs between a virtual first tangent plane of the cross section through the nozzle opening and a virtual second tangent plane of the cross section opposite thereto and parallel to the first tangent plane divides the cross section into a first cross-sectional area at the nozzle opening. The cross-sectional surface of the first cross-sectional area differs from the cross-sectional surface of the second.

Abstract: A method for depositing a plasma polymer layer in an atmospheric-pressure plasma on a metallic substrate, wherein the plasma is obtained by a discharge between two electrodes. At least one organic coating precursor compound is fed into the region of the relaxing plasma and is deposited on the metallic substrate as a plasma polymer layer. Nitrogen or a forming gas is used as a treatment gas and the at least one organic coating precursor compound is selected from various compounds. Also disclosed is an article, an electrode and a capacitor which utilize the method and include a metallic substrate having a surface and a plasma polymer layer on the surface. Also disclosed is a method for producing the electrode or for producing the capacitor, a battery cell or a lithium-ion accumulator which comprises the electrode.

Abstract: An apparatus for plasma treating a substrate comprises a high voltage source of frequency 3 kHz to 30 kHz connected to at least one needle electrode (11) positioned within a channel (16) inside a dielectric housing (14) having an inlet for process gas and an outlet. The channel (16) has an entry (16a) which forms the said inlet for process gas and an exit (16e) into the dielectric housing arranged so that process gas flows from the inlet through the channel (16) past the electrode (11) to the outlet of the dielectric housing. The apparatus includes means for introducing an atomised surface treatment agent in the dielectric housing, and support means (27, 28) for the substrate (25) adjacent to the outlet of the dielectric housing.
