ALC-Foil Carbon-Coated Aluminium Foil Current Collector

ALC-Foil is a carbon-coated aluminium foil current collector designed for lithium-ion battery cathode electrode fabrication. A thin conductive carbon layer is applied to aluminium foil to improve electrical contact between the active material coating and the metal collector, helping to reduce interfacial contact resistance and improve coating uniformity during slurry casting.

How it works

In conventional cathodes, the interface between aluminium foil and the composite coating can contribute to contact resistance and local delamination, especially at higher C-rates. The carbon-coated surface provides a more conductive, higher-energy interface that supports:

• improved wetting and coating adhesion
• more consistent current distribution across the electrode
• reduced polarisation in demanding charge/discharge profiles
  
  

Key specifications (typical)

• Surface wetting tension: ≥ 50 dyne/cm
• Aluminium foil width: 250 ± 1.0 mm
• Carbon coating width (S1/S2): 224 ± 1.0 mm (double-sided coated region)
• Aluminium substrate thickness: 15 ± 1.0 µm
• Total thickness (with coating): 17 ± 1.0 µm
• Tensile strength: ≥ 150 MPa
• Extensibility: 1.5% to 4.0%
  
  

Compatibility & applications

Suitable for R&D and pilot-scale cathode preparation for lithium-ion systems such as LFP, NMC/NCA, LCO and high-rate formulations where adhesion and impedance control are important. Compatible with standard electrode coating, drying, calendaring and slitting workflows.
