Performance advantages of carbon-coated aluminum foil
1. Significantly improve the consistency of battery pack usage and greatly reduce the cost of battery packs. Such as: significantly reduce the dynamic internal resistance increase of the battery cell; improve the consistency of the pressure difference of the battery pack; prolong the life of the battery pack; greatly reduce the cost of the battery pack.
2. Improve the adhesion between the active material and the current collector, and reduce the manufacturing cost of the pole piece. Such as: improving the adhesion of cathode materials and collectors using aqueous systems; improving the adhesion of nano- or sub-micron cathode materials and collectors; improving the adhesion of lithium titanate or other high-capacity anode materials and collectors; The qualified rate of pole piece manufacturing is improved, and the manufacturing cost of the pole piece is reduced.
After using the carbon-coated aluminum foil, the adhesion of the pole piece was increased from the original 10gf to 60gf (using 3M tape or a hundred grid knife method), and the adhesion was significantly improved.
3. Reduce polarization, increase rate and gram capacity, and improve battery performance.
Such as: partially reducing the proportion of binder in the active material, increasing the gram capacity; improving the electrical contact between the active material and the current collector; reducing polarization and improving power performance.
4. Protect current collectors and prolong battery life. For example: prevent the corrosion and oxidation of the current collector; improve the surface tension of the current collector and enhance the easy coating performance of the current collector; it can replace the etched foil with higher cost or replace the original standard foil with a thinner foil.
