1. An electrically conductive film for a cell contacting unit for a battery, the electrically conductive film having:
an electrically nonconductive substrate layer;
an electrically conductive metal layer that has a structure produced by material removal and that on a first side is joined, at least in sections, to the electrically nonconductive substrate layer; and
an electrically nonconductive cover layer having a structure that is produced by material removal;
wherein the electrically conductive metal layer is located on a second side and is joined, at least in sections, to the electrically nonconductive cover layer;
wherein a material of which the electrically nonconductive substrate layer is made has a modulus of elasticity in the range of 10 to 100 megapascals;
wherein the material of which the electrically nonconductive substrate layer is made has a lower modulus of elasticity than a material of which the electrically nonconductive cover layer is made; and
wherein a difference between the modulus of elasticity of the material of which the electrically nonconductive substrate layer is made and the modulus of elasticity of the material of which the electrically nonconductive cover layer is made is at least 20 megapascals.
