Abstract
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.
