CC9-S Single-side carbon coated copper foil

CC9-S single-side carbon-coated copper foil is a specialised anode current collector designed for lithium-ion battery and next-generation battery research. It combines a high-purity copper substrate with a thin, conductive carbon surface layer to improve electrode adhesion and interfacial behaviour during slurry coating, calendaring, and cycling.

Working principle and mechanism

In conventional Cu current collectors, poor wetting or limited mechanical “anchoring” between the copper surface and the anode coating can contribute to delamination, increased contact resistance, and uneven current distribution. A uniform carbon coating provides a conductive, higher-surface-area interface that can enhance bonding with binder/carbon networks and promote more stable electronic contact across the electrode–collector interface. This is particularly useful for high-loading graphite, silicon–graphite blends, and challenging systems where interfacial resistance or adhesion is a limiting factor.

Key specifications

• Carbon coating: single-side, ~2 µm conductive carbon layer
• Copper substrate: >99.9% purity, ~9 µm thickness
• Total thickness: ~11 µm
• Coating width: 560 mm
• Total width: 590 mm
• Packaging: vacuum bag (to help minimise contamination and moisture uptake)
  
  

Compatibility and typical uses

• Anode coating processes for graphite, Si/graphite, hard carbon, and R&D-scale roll-to-roll trials
• Battery testing workflows alongside potentiostats/galvanostats, battery cyclers, and electrode processing tools
• Suitable for researchers optimising adhesion, rate capability, and reproducibility in coin, pouch, and prototype cells
