The aluminum foil/copper foil surface is coated with carbon coating layer, which is used as current collectors for the cathode/anode electrode of lithium-ion battery.

The dispersed nano conductive graphite and carbon coating particles are evenly and finely coated on the aluminum foil/copper foil.

The coating of carbon aluminum foil significantly improves the overall performance of the battery

Inhibit the polarization of the battery, reduce the thermal effect,
improve the rate performance to reduce the internal resistance of the battery, and significantly reduce the increase
in the dynamic internal resistance of the cycle process,
improve the consistency, increase the cycle life of the battery,
improve the adhesion of the active substance and the collector, reduce the manufacturing cost of the pole sheet, and protect the collector from being corroded by the electrolyte.

• Low investment cost: coating and drying on both sides at the same time, reducing unit structure.
• Large capacity of single machine: mechanical speed 200m/min, coating speed 180m/min.
• Stability: double guide rails with direct-drive reel structure.
• Graphene infrared heating：40% reduction in heating energy consumption.
• Air suspension oven: Wind velocity deviation at the nozzle≤5%, dry and stable operation.
