Performance advantages of carbon foil/copper foil coating

1. Significantly improve the consistency of battery pack use and greatly reduce the cost of battery pack. Such as:

· Significantly reduce the increase of dynamic internal resistance of the cell;

· Improve the differential pressure consistency of the battery pack;

· Extend battery life;

· Significantly reduce battery pack costs.

2. Improve the adhesion of the active material and the collector, and reduce the manufacturing cost of the pole sheet. Such as:

· Improve the adhesion of cathode materials and collectors using water-based systems;

· Improve the adhesion of cathode materials and collector at the nanoscale or submicron scale;

· Improve the adhesion of lithium titanate or other high-capacity negative electrode materials and collectors;

· Improve the qualified rate of electrode sheet and reduce the manufacturing cost of electrode sheet.

3. Reduce polarization, improve magnification and gram capacity, and improve battery performance.

· If the proportion of adhesive in the active material is partially reduced, the gram capacity is increased;

· Improve the electrical contact between the active substance and the collector;

· Reduce polarization and improve power performance.

4. Protect the fluid collection and extend the battery life. Such as:

· Prevent collector corrosion and oxidation;

· Improve the surface tension of the collector, and enhance the coating performance of the collector;

· Can replace higher-cost etched foil or replace standard foil with thinner foil
