Copper foil is used to produce CCL and Lithium batteries. The global copper foil productivity is limited, and more copper foil are used for Lithium batteries with the increasing demand from electrical vehicles,and less is allocated for the CCL. In recent years, the copper foil industry has also competed fiercely, this has resulted in diminishing return on investment, which results in a further decrease of supply and CCL manufacturers can now not keep up with the increasing demand.
