Cu-F Copper foil

The Cu Anode Current Collector Copper Foil (Cu ≥99.9%) supplied by ScienceGears is a battery-grade, rolled copper foil manufactured for high-performance lithium-ion battery research and pilot-scale production. Produced using controlled electrodeposition and rolling processes, this foil offers excellent electrical conductivity, mechanical stability, and surface consistency, making it ideal for advanced electrochemical studies.

Working Principle and Role in Batteries

In lithium-ion batteries, copper foil acts as the anode current collector, providing a low-resistance pathway for electron transport during charge and discharge. Its high purity and uniform thickness ensure minimal internal resistance, stable cycling behaviour, and reliable electrochemical performance, particularly for graphite, silicon, and silicon-composite anodes.

Key Features and Specifications

• Thickness options: 8 µm, 10 µm (other sizes available on request)
• Standard width: 100–300 mm (200 mm typical)
• Purity: Cu ≥99.9%
• Areal density: 85–90 g/m² (10 µm)
• Tensile strength: ≥300 MPa
• High-temperature tensile strength (180 °C): ≥150 MPa
• Surface roughness (Rz):
• Drum side: <0.3 µm
• Matte side: <3.5 µm
• Surface tension: 65 dyne/cm (both sides)

The controlled surface roughness improves adhesion of anode slurries, while high thermal stability supports electrode drying and calendaring processes.
