Punched Copper Foil is a lightweight current collector designed for advanced lithium-ion battery electrodes. The punched structure reduces collector mass while increasing active material loading, helping improve energy density and electrolyte accessibility. Suitable for battery research, prototype development, and electrode manufacturing.
