Carbon-Coated Aluminum Foil Li-Ion Battery Cathode

Description

Carbon-Coated Aluminum Foil — Li-Ion Battery Cathode Current Collector

Conductive carbon-coated aluminum foil for lithium-ion battery cathode current collectors. The carbon interlayer improves adhesion of NMC, LFP, LCO, and NCA cathode slurries, reduces contact resistance, and enhances cycle stability — especially important for high-loading thick cathode research.

Key Specifications

• Al foil thickness: 12 µm, 15 µm, 20 µm, 25 µm (standard)
• Carbon coating: 3 µm – 8 µm per side
• Surface resistance: <1 Ω/sq
• Purity: ≥99.5% Al (1N5 grade)
• Tensile strength: ≥100 MPa

Applications

• NMC/LFP/LCO cathode current collector
• High-loading thick cathode research
• Sodium-ion battery cathode substrate
• Supercapacitor electrode substrate
