Thermosensitive High-Surface-Area Double-Sided Carbon-Coated Copper Foil for Dry-Process Electrodes
The material is a copper-foil current collector intended for dry-process electrode fabrication. The foil has a thermosensitive, high-surface-area carbon coating applied to both sides, providing interfacial contact and coating adhesion used for dry electrode processing.
Customized widths and single-/double-sided coating configurations are available upon request.
