The invention relates to a method for producing an aluminum strip, in which the aluminum strip is coated with a sorption layer which has a binder and a sorbent. The object to propose a method for producing an aluminum strip coated with a sorption layer, by means of which an aluminum strip can be coated cost-effectively having constant performance characteristics with respect to the sorption of, for example, water vapor, is achieved according to the invention by means of a method for producing an aluminum strip coated with a sorption layer by applying a suspension to the aluminum strip in the coil-coating process, which in addition to a liquid comprises at least one binder, formed as a solid, and a sorbent, and by subjecting the aluminum strip, together with the applied suspension, to a drying process, in which the binder is activated.

Sorbent-coated aluminium strip

A method for producing a strip consisting of aluminum or an aluminum alloy for packaging purposes, in particular for cans, can lids or can closures, which provides an individualized aluminum strip for packaging purposes, with which decorative or identification elements can be reliably embossed without additional production steps being required, for example at the producer of the packaging means, is achieved in that decorative or other identification elements are embossed into the strip in the last rolling pass of cold rolling and in that the strip thickness is greater in the area of the decorative and identification elements than in the remaining areas of the strip.

Method for producing a strip for packaging purposes

The invention relates to a current collector foil made of aluminum or an aluminum alloy, to the use of the current collector foil for batteries or accumulators, in particular lithium-ion accumulators, and to a method for producing the current collector foil. The object of providing a current collector foil, which has very good properties with regard to conductivity and tensile strength, and which can also be produced economically, is achieved in that the current collector foil has an acid-pickled or alkali-pickled surface.
