Advantages of carbon-coated aluminum foil in lithium battery application:
1. Restrain battery polarization, reduce the thermal effect and improve multiplier performance;
2. Reduce the internal resistance of the battery, and significantly reduce the increase of dynamic internal resistance in the cycle process;
3. Improve the consistency and increase the cycle life of the battery;
4. Improve the adhesion between active substances and collecting fluid, and reduce the manufacturing cost of the polar plate;
5. Protect the collecting fluid from being corroded by an electrolyte;
6. Improve the processing performance of lithium iron phosphate and lithium titanate materials.
Coating thickness on both sides: A 4 ~ 6 muon, B 2 ~ 3 muon.
