Cathode Foils for Lithium-ion Batteries

Targray offers a range of Aluminium (Al) cathode foils for various uses in the development Lithium-ion batteries. A Lithium-ion battery has a device at each electrode for collecting and taking out electricity. Metallic foils are used in Lithium-ion batteries as current collectors and during the battery manufacturing process, anode and cathode slurries are coated on to the respective foil types.

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.
