Battery-Grade Foils for LiB Cell Manufacturers


Serving as the bridge between external electronics and internal li-ion transports, current collectors account for over 90% of the electric conductivity and ∼90% of the mechanical strength of the electrode in lithium-ion batteries (LiB). As such, selecting the right anode and cathode battery foil materials is critical to battery developers seeking to maximize the performance of their cells.

Supported by a global network of foil manufacturing partners, Targray is a leading North American supplier of battery-grade foil materials for lithium-ion based energy storage technologies. Our advanced rolling and alloy manufacturing processes allow us to deliver uniformly thick, high-strength aluminum (cathode) foil and copper (anode) foil materials to Li-ion cell manufacturers worldwide.

Aluminum Foil for Li-ion Battery Cathodes


Aluminum foil must be produced using optimal aluminum alloys in order to meet the performance requirements of Lithium-ion batteries. Targray supplies high-performance, high-quality lithium-ion battery foils for applications such as automotive (EV) and consumer electronics, from alloys carefully chosen for those specific demands.

Our aluminum foil product line is the result of many years of battery material research and development integrated with upstream processes. Our Al foils are produced utilizing superior aluminum alloys developed specifically for the lithium-ion battery market, with rolling technologies capable of manufacturing foil rolls ranging from 0.01-0.03mm in thickness.

Rolled Copper Foil for Li-ion Battery Anodes


Available in thicknesses ranging from 5-12μm, Targray rolled copper foils are produced via a cutting edge manufacturing process that delivers exceptional tensile strength and high elongation, which in turn minimizes the occurrence of foil deformation, fracturing and wrinkling.

The excellent handling properties of our rolled copper foils materials make them the ideal solution for LiB manufacturers seeking to enhance the performance of their lithium-ion cells, increase their productivity, and lower their material costs.
