Double-Sided Carbon-Coated 316L Stainless Steel Foil (for Aqueous Zn)

Double-Sided Carbon-Coated Stainless Steel Foil (for Aqueous Zn Batteries)

This material is a carbon-coated 316L stainless steel current collector specifically designed for aqueous zinc battery systems.
The stainless steel substrate offers excellent mechanical stability and corrosion resistance, while the double-sided carbon coating provides enhanced electrochemical compatibility, improved interface stability, and reduced contact resistance.
Custom widths and single-sided or double-sided coating configurations are available upon request.
