Carbon Coated Aluminum Foil Modified AL aluminum Foils

CAW2 12-100um Carbon Coated Aluminum Foil No Exfoliation

Current collector conductive Modified carbon-coated aluminium Foil for Lithium-ion batteries Super capacitor.

Carbon Coated Aluminum Foil Advantage:

1. Improve the consistency of battery usage group and reduce battery cost significantly.
2. Improve the adhesion of active material and the collector, and reduce the electrode manufacturing cost.
3. Reduce the polarization, increase the rate and capacity, improve the battery performance.
4. Protection of fluid collection, extend battery life.

CAW2 is one of the best price-ratio “CA” series product, This product shows comparable performance to foreign products, which breaks through the monopolization of conventional carbon-coated Al foil in international market. Conductive carbon is used as main coating material, and special resin is selected as binder. The coating slurry is casted onto both sides of Al foil using an advanced coating machine ,of which the coating velocity can be 150m per minute , in addition,the coatings with various gaps can be realized, resulting the reduce of the production cost.

Application:

1. (LFP.LMO.NCM.NCA.LNM.LTO):for electric vehicles and energy storage(LFP.LMO.NCM.NCA.LNM.LTO)
2. (LCO.NCM):Lithium-ion batteries for 3C productions(LCO.NCM)
3. Supercapacitor
4. Lithium-ion supercapacitor

Advantages

1. Improve the surface tension, and increase the adhesion between the aluminium foil and the active material.
2. Decrease the using amount of binder for the electrode ,enhance energy density of the battery ,and lower the cost of the electrode production
3. Protect the AI current collector from surface corrosion and oxidation.
4. Reduce interface resistance and internal resistance of the cell.
5. Decrease polarization and improve the rate capability and specific capacity of the electrode material
6. Mitigate exothermic reactions and enhance the battery safety
7. Improve the production stability and reproducibility ,and raise the pass rate of the cell
8. Increase the consistency and cycling life of the cell,and lower the cost of the production.
