Advantages of carbon-coated aluminum foil in lithium battery applications:
1. Inhibit battery polarization, reduce thermal effects, and improve rate performance;
2. Reduce the internal resistance of the battery, and significantly reduce the dynamic internal resistance increase during the cycle;
3. Improve the consistency and increase the cycle life of the battery;
4. Improve the adhesion between the active material and the current collector, and reduce the manufacturing cost of the pole piece;
5. Protect the current collector from being corroded by the electrolyte;
6. Improve the processing performance of lithium iron phosphate and lithium titanate materials.
Coating double-sided thickness: Type A 4~6μm, Type B 2~3μm.
