Performance advantages of coated carbon aluminum foil/copper foil

Performance advantages of carbon - coated aluminum foil

Performance advantages of carbon - coated aluminum foil

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

· significantly reduce the increase of core dynamic internal resistance;

· improve the voltage difference consistency of the battery pack;

· extend battery life;

· substantially reduce battery pack costs.

2. Improve the adhesive adhesion of active materials and fluid collection, make the materials soft, easy to process, and reduce the manufacturing cost of polar plates. Such as:

· improve adhesion of anode materials and collector with water-based system;

· improve adhesion of nanometer or submicron anode materials and collector;

· improve adhesion of lithium titanate or other high capacity cathode materials and collector;

· improve the qualified rate of electrode making and reduce the manufacturing cost of electrode making.

The adhesion force of carbon coated aluminum foil back electrode was increased from 10gf to 60gf (3M adhesive tape or bag-knife method), and the adhesion force was significantly increased.

3. Reduce polarization, increase the multiplier and gram capacity, and improve battery performance.

· for example, partially reduce the proportion of adhesives in active materials and increase the capacity of grams;

· improve electrical contact between active substances and fluid collection;

· reduce polarization and improve power performance.

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

· prevent collector corrosion and oxidation;

· improve the surface tension of the collector and enhance its easy coating performance;

· alternative to high cost etching foil or to replace the original standard foil with a thinner foil.
