Thermo-responsive Carbon-Coated Aluminum Foil (Dry Electrode Compatible)

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

The 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 conductivity, interfacial contact, and electrode stability under dry-process fabrication conditions.
