According to the application, aluminum foil mainly includes packaging aluminum foil (food and pharmaceutical packaging) decorative aluminum foil, mechanical and electrical equipment aluminum foil (transformer aluminum foil, etc.), beer sealing foil, cigarette foil, household aluminum foil, etc. Let me introduce to you the performance advantages of carbon-coated aluminum foil/copper foil.
Performance advantages of carbon-coated aluminum foil/copper foil
1. Significantly improve the consistency of battery pack usage and significantly reduce battery pack costs. like:
· Significantly reduces the increase in dynamic internal resistance of the battery;
· Improve the pressure difference consistency of the battery pack;
· Extend the life of the battery pack;
·Significantly reduce battery pack costs.
2. Improve the bonding adhesion between active materials and current collectors and reduce the manufacturing cost of pole pieces. like:
· Improve the adhesion of cathode materials and collectors using water-based systems;
· Improve the adhesion between nanoscale or submicron cathode materials and collectors;
· Improve the adhesion between lithium titanate or other high-capacity anode materials and collectors;
· Improve the qualification rate of pole pieces and reduce the manufacturing cost of pole pieces.
After using carbon-coated aluminum foil, the adhesion of the pole piece is increased from the original 10gf to 60gf (using 3M tape or the hundred-grid knife method), and the adhesion is significantly improved.
3. Reduce polarization, increase rate and gram capacity, and improve battery performance.
· For example, partially reduce the proportion of binder in the active material and increase the gram capacity;
· Improve the electrical contact between the active material and the current collector;
· Reduce polarization and improve power performance.
