Aluminum Cathode Foils (Al Foil) for Energy Storage

Targray offers a range of Aluminum (Al) cathode foils for various uses in the development Lithium-ion batteries. Our advanced rolling and alloy technologies allow us to develop uniformly thick, high-strength aluminum foil optimized for lithium-ion batteries.

About Our Aluminum Foil Product Line

Targray offers all of these metallic foils for use in the final slurry application. The Aluminum foils have excellent performance in lithium-ion cell manufacturing. Targray offers a range of Aluminum foils depending on the application of the Li-ion battery. A rolled foil (RA-type), made from wrought Cu is generally used for high-energy, high-power applications. Al foil is extensively used in consumer electronics and electric power tools. It is also widely used in Hybrid and Electric vehicle (EV) battery applications.
