12+0.8+0.8 Battery Cathode Collector Carbon Coated Aluminum Foil

12+0.8+0.8 Battery Cathode Collector Carbon Coated Aluminum Foil is a composite material made from pure aluminum foil substrate with a conductive carbon layer applied on the surface through gravure coating. Widely adopted as the positive electrode current collector for lithium-ion batteries, it lowers interfacial contact resistance, strengthens bonding between conductive active materials and the substrate, inhibits aluminum foil oxidation and corrosion, delivers more consistent cell performance, prolongs battery cycle life and boosts overall safety.
