Available from a thickness of 4.5μm, our battery copper foil product includes electrodeposited (ED) copper foils, rolled annealed (RA) foils, high-tensile alloy (HTA) foils, and roll-clad foils. These combine copper’s excellent conductivity with materials such as aluminium, tin, and silver to provide unique performance benefits.
Our manufacturing follows strict quality management procedures and uses innovative handling technologies to ensure that customers consistently receive high-quality foils for their battery production projects. For purchasing enquiries, please contact us.
Electrodeposited (ED) Copper Foils
Our high-performance ED copper foils are manufactured using a specialised process that includes dissolution, electroplating, and roll slitting. Available in thicknesses ranging from 4.5μm to 12μm, these foils are known for their exceptional tensile strength and enhanced elongation properties.
Standard ED Copper Foils
- Standard battery-grade copper foils designed for various lithium-ion battery (LiB) applications.
- Cost-effective options in thicknesses ranging from 4.5μm to 12μm.
- Reliable foils with uniform thickness and surface smoothness.
- Includes a variant designed to improve elongation rates in cylindrical battery applications.
High Elongation ED Copper Foils
- Battery-grade copper foils with superior tensile strength and elongation.
- Reduces wrinkling, folding, and fracturing during the cell manufacturing process.
- Low deformation under high pressure, allowing for the application of additional active material coatings.
- Ideal for use with metal-based active materials such as silicon (Si) or tin (Sn).
Ultra-Thin ED Copper Foils
- Exceptionally thin (4.5μm) battery-grade copper foils with high tensile strength.
- Excellent handling characteristics, allowing for the production of high-capacity batteries at lower costs.
- Available in commercial quantities for large-scale lithium-ion battery manufacturing.
- Ideal for LiB applications requiring lightweight and compact designs, such as consumer electronics and drones.
