Lithium-ion Battery Foils

Targray offers Metallic foils which are used in Lithium-ion batteries as current collectors. Typically, Aluminum Foil is used as the positive electrode for the cathode current collector and Copper Foil is used as the negative electrode for the anode current collector. During the battery manufacturing process, anode and cathode slurries are coated on to the respective foil types.

Electrodeposited (ED) Copper Foil

An ED foil is used in high-energy, low-power applications such as Li-ion batteries for cell phones, laptops and consumer electronics. Targray’s supplier is the quality leader in the industry, with R&D capabilities for new product innovations and with the ability to customize the foil characteristics as requested by our battery manufacturing customers. We offer very cost-effective battery foil materials with a service level that is leveraged by our global distribution presence.

Features of our ED Copper Foil:

• High adherence to active material
• Excellent tensile strength
• High elongation
• Range of micron thickness available
