Carbon-Coated Copper Foil — Li-Ion Battery Anode Current Collector
Conductive carbon-coated copper foil for lithium-ion battery anode current collectors. The thin carbon layer (5–10 µm both sides) greatly improves adhesion of graphite and silicon-graphite active materials, reduces interfacial resistance, and suppresses copper dissolution at low voltages. Standard for next-generation battery research.
