Performance advantages of carbon-coated copper foil
1. Significantly improve the consistency of battery pack usage and significantly reduce battery pack costs.
· Significantly reduce the increase in dynamic internal resistance of the battery;
· Improve the pressure difference consistency of the battery pack;
· Extend battery pack life.
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 of lithium titanate or other high-capacity anode materials and collectors;
· Improve the qualification rate of pole pieces and reduce pole piece manufacturing costs.
3. Reduce polarization, increase rate and gram capacity, and improve battery performance. like:
· Partially reduce the proportion of binder in active materials and increase gram capacity;
· Improve the electrical contact between the active material and the current collector;
· Reduce polarization and improve power performance.
4. Protect current collector and extend battery life. like:
· Prevent collector corrosion and oxidation;
· Improve the surface tension of the current collector and enhance the easy coating performance of the current collector;
· Can replace higher cost etched foils or replace original standard foils with thinner foils.
