What is Carbon-Coated Aluminum Foil?
Carbon-coated aluminum foil has a thin conductive carbon layer on the aluminum current collector. The coating lowers contact resistance, improves adhesion of the cathode layer and reduces polarization, which helps rate performance and cycle life, especially for LFP and other low-conductivity cathodes.
Carbon Coated
Advantages
1. The inhibition of cell polarization, reduces the heating effect and improves the rate performance;2. Reduce the battery internal resistance, and decrease the circulation process of dynamic resistance increase;
3. Improve the consistency, increase the battery cycle life;
4. Improve the adhesion of and active materials, reduce the pole piece manufacturing cost;
5. Protect collection of fluid from the electrolyte corrosion;
6. Improve lithium iron phosphate, lithium titanate materials processing performance.
Conductive coating:
Using functional coatings for surface treatment of battery conductive substrate is a breakthrough of technical innovation, coated carbon foil/copper foil is to spread good nano conductive graphite and carbon-coated particles, fine and uniform coating on aluminum foil/copper foil. Static electrical conductivity can provide an excellent collection of active material micro electric current, which can greatly reduce the positive/negative material and collector, the contact resistance between the and can improve the adhesive ability between the two, can reduce the use amount of binder, which creates a significantly improve the overall performance of the battery. Can be divided into water-based coating (water system) and oil (organic solvent system) two types
