Pure copper foil is critical for lithium-ion battery hybrid electric vehicle (HEV) components, such as the anode, because it is lightweight, has specific tensile strength, and controlled elongation. Advanced copper foil has the optimum combination of mechanical and electrical properties needed to operate safely and effectively in the battery modules. In addition to battery components, copper foil is used in HEVs for the various electrical/components. The electrical systems of hybrid and battery electric vehicles (HEVs) require a significant amount of copper due to its excellent electrical conductivity and mechanical strength.  

Specific Applications Of Pure Copper For HEV

Wiring and busbars. HEVs use a large amount of copper for the high-voltage wiring and large-gauge busbars.

Motors. The copper windings in the electric motors are a significant use of copper and are essential for the magnetic fields needed for rotation.

Charging infrastructure. Charging cables and connectors for HEVs incorporate copper.
