The surface treatment of battery conductive substrates with functional coatings is a breakthrough technological innovation. Carbon-coated aluminum foil and Carbon-coatedcopper foil is to coat dispersed nano-conductive graphite and carbon coated particles evenly and delicately on aluminum foil and copper foil. It can provide excellent static electrical conductivity, collect the micro current of the active material, which can greatly reduce the contact resistance between the positive and negative electrode material and the current collector, and can improve the adhesion between the two and reduce the adhesion The amount of agent used, in turn, significantly improves the overall performance of the battery.

Performance advantages of conductive coating carbon-coated aluminum foil and copper foil:

1. Significantly improve the consistency of the battery pack and greatly reduce the battery composition cost.

2. Improve the adhesive force of the active material and the current collector, and reduce the manufacturing cost of the pole piece.

3. Reduce polarization, increase rate and gram capacity, and improve battery performance.

4. Protect the current collector and prolong the service life of the battery.
