Abstract
The invention relates to an electrically conductive film (10) having an electrically nonconductive substrate layer (12), and an electrically conductive metal layer (14) that has a structure produced by material removal and that on a first side is joined, at least in sections, to the substrate layer (12).
Claims15
A cell contacting unit for a battery, in particular a vehicle battery, comprising:
- one or more electrically conductive films comprising:
- an electrically nonconductive substrate layer that is made of a polyethylene;
- an electrically conductive metal layer that is made of copper, a copper alloy, aluminum, and/or an aluminum alloy, and 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;
- wherein the structure of the electrically conductive metal layer includes one or more strip conductors, and at least one of the one or more strip conductors includes multiple strip conductor sections whose strip conductor widths differ from one another;
- wherein a difference between a modulus of elasticity of the polyethylene of which the electrically nonconductive substrate layer is made and a modulus of elasticity of a material of which the electrically nonconductive cover layer is made is at least 20 megapascals.
