Thermosensitive High-Surface-Area Double-Sided Carbon-Coated Aluminum Foil for Dry-Process Electrodes

This material is designed as a current collector for dry-process electrodes.
It consists of an aluminum foil substrate coated on both sides with a thermosensitive, high-surface-area carbon layer. The coating provides improved conductivity, optimized interfacial contact, and enhanced electrode stability under dry-process fabrication conditions.

Specifications

Substrate thickness: 14 um
Width: 180 mm
Application: Dry-process electrode current collector

Packaging

12 um aluminum substrate, 180 mm width; double-sided carbon coating, 1 um per side, 152 mm coated width; 1.5 kg per roll. Custom widths and single-sided or double-sided coating configurations are available upon request.
