Significantly improve the consistency of battery pack usage and significantly reduce battery pack costs. For example, significantly reducing the increase in dynamic internal resistance of the battery cell;

　　·Improve the consistency of the differential pressure of the battery pack;

　　·Extend the lifespan of the battery pack;

　　·Significantly reduce battery pack costs.

　　2. Improve the adhesion between the active material and the collector, and reduce the manufacturing cost of the electrode. For example:

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

　　·Improve the adhesion between nano or submicron level positive electrode materials and collectors;

　　·Improve adhesion between Lithium titanate or other high-capacity anode materials and collector;

　　·Improve the qualification rate of electrode fabrication and reduce the cost of electrode fabrication.

　　Adhesion test diagram of battery electrode coated with carbon aluminum foil and light foil

　　After using carbon coated aluminum foil, the adhesion force of the electrode was increased from 10gf to 60gf (using 3M tape or a hundred grid knife method), and the adhesion force was significantly improved.
