Name: Conductive Primer Coated Aluminum Foil for Lithium-Ion Battery Cathodes

Material Type: Carbon-Based Conductive Primer Coated Aluminum Foil, 14 μm Total Thickness

Product Code: XN-CPAF-14

Product Introduction:

This product is a critical material for lithium-ion batteries, manufactured by coating aluminum foil with a conductive carbon-based composite slurry, primarily designed to enhance battery performance and process stability. It features high surface wetting tension and excellent NMP solvent resistance, ensuring reliable adhesion and coating integrity throughout electrode manufacturing. Width, coating width, and blank width can all be customized to order.
