AL-Foil-16 Aluminium Current Collector Foil (Al, 16 µm)

AL-Foil-16 is a battery-grade aluminium foil designed for use as a cathode current collector in lithium-ion and related rechargeable battery systems. In electrode fabrication, the aluminium foil acts as the low-resistance electronic pathway between the active-material coating and the external tab/terminal, supporting stable charge transfer during cycling and enabling uniform current distribution across the electrode area.

Key Specifications and Material Details

• Foil thickness: 16 µm (battery current collector grade)
• Purity: ≥ 99.0% Al
• Pinholes/penetration holes: None (as per test report)
• Surface (areal) density: 38–42 g/m²
• Temper/metal state: H16 / H18
• Thickness tolerance: 0–1 µm
• Surface roughness (Ra): smooth side ≤ 0.4 µm; rough side 0.35–0.75 µm
• General width range: 100–300 mm (typical roll formats; other widths may be available by request)
  
  

Compatibility and Use

This aluminium current collector foil is compatible with common cathode coating workflows, including slurry casting, drying, calendaring, and punching for coin cells, pouch cells, and lab-scale laminated electrodes. Dual-surface roughness options can assist with coating adhesion and interfacial contact optimisation, depending on binder chemistry and coating method.

Typical Applications

• Li-ion cathodes (NMC, LFP, NCA and related systems)
• Sodium-ion and alternative cathode research (where aluminium collectors are appropriate)
• Lab prototyping for pouch/coin cell assembly and electrochemical testing
