Anode Foils for Cell Manufacturers

Targray’s extensive anode foil portfolio includes a variety of metallic foils used in Lithium-ion batteries as current collectors. These include copper foils, nickel foils and rolled copper alloy foils – materials frequently used in the li-ion battery manufacturing process.

Typically, Copper Foil is used as the negative electrode for the anode current collector and Aluminum Foil is used as the positive electrode for the cathode current collector. During the battery manufacturing process, anode and cathode slurries are coated on to the respective foil types. See the tables below for additional information about our anode foils.

Copper Foils for Battery Manufacturing

Targray Copper FoilsOur line of high-performance copper foil materials has been developed to meet the specific needs of the lithium-ion battery manufacturing industry. Used primarily in commercial-scale production, Targray copper foils are designed in a world-class manufacturing facility and can be supplied in quantities of up to 1000T per month.

Rolled Copper Alloy Anode Foil

Targray supplies rolled copper anode foil for lithium-ion battery manufacturing. Our specialty copper alloys are used in an increasingly wide range of applications, notably printed circuits, electromagnetic shielding and rechargeable batteries. Key Features and benefits include:

  • High conductivity to minimize cell impedance.
  • Excellent for high power applications: Drive-Train and power tools.
  • Heat resistance: offering high heat tensile and ductile strength.
  • Consistently smooth surface; no large protrusions.
  • Surface treatment for adhesion enhancements.

Electrodeposited (ED) Copper Anode Foil

An ED foil is used in a wide range of applications such as Li-ion batteries for cell phones, laptops and consumer electronics. Our 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 include:

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

Electrodeposited (ED) Nickel Anode Foil

Nickel foil has been used for years in many applications such as printed circuit boards. It actually has many features which make it suitable for use in Lithium Ion Batteries and Super Capacitors. Nickel foil is electro conductive, it’s anti-corrosive properties are higher than copper and stainless steel foil. It can be produced wider and thinner than the more commonly used rolled Copper foil. Nickel foil is also magnetic. It can be used as electromagnetic interference material; for example shielding tape for various electronic devices and as conductive tape.

Features of our ED Nickel Foil:

  • Excellent acid and heat resistance, and etching ability
  • Keeps high tensile strength even after annealed
  • Higher purity (99.95%) than rolled nickel foil
  • Range of micron thickness available including ultra-thin (4 to 50 microns)

Working closely with our supply partners and organizations including the Electrochemical Society and NAATBatt International, we help battery manufacturers and researchers worldwide commercialize ambitious new technologies for the energy storage market.
