CC9-D Double-Side Carbon Coated Copper Foil

CC9-D is a double-side carbon coated copper foil designed as a high-performance anode current collector for lithium-ion and next-generation battery electrodes. A thin conductive carbon layer on both sides improves interfacial contact between the copper substrate and the electrode coating (e.g., graphite, silicon-graphite, hard carbon), supporting stable adhesion, reduced contact resistance, and more uniform current distribution during cycling.

How it works

In slurry-cast electrodes, the “collector–coating” interface strongly influences impedance growth, delamination risk, and high-rate behaviour. The carbon coating provides a conductive, surface-engineered layer that can enhance binder anchoring and electronic pathways at the interface, helping maintain low resistance and mechanical integrity through calendering and repeated charge–discharge expansion/contraction.
