Abstract

The invention relates to a current collector foil for batteries, accumulators or capacitors, comprising a carrier material and at least one electrically conductive layer made from a metal. Moreover, the invention relates to a method for producing a corresponding current collector foil as well as to the advantageous use thereof. The object of providing a current collector foil for batteries, accumulators or capacitors, which is optimized in relation to the contact surface and the adhesive properties and which results in an improved service life, is achieved as a result of the fact that the at least one electrically conductive layer is produced at least partially by electrodepositing a metal and has a texture.
