[China Aluminum Industry Network] 1. Significantly increase the consistency of battery packs and significantly reduce the battery composition. Such as: significantly reduce the increase of dynamic resistance of the battery core; increase the pressure uniformity of the battery pack; extend battery life; significantly reduce the battery composition. 2. Improve the adhesion and adhesion of active materials and current collectors and reduce the manufacturing cost of pole pieces. Such as: to improve the use of aqueous system of positive electrode material and collector adhesion; to improve the nano-or sub-micron positive electrode material and collector adhesion; improve the adhesion of lithium titanate or other high-capacity anode material and collector; Improve the pass rate of the pole piece and reduce the manufacturing cost of the pole piece. 3, reduce polarization, increase magnification and g capacity, improve battery performance. Such as partially reducing the proportion of the binder in the active material, increasing the gram capacity; improving the electrical contact between the active material and the current collector; reducing the polarization and improving the power performance. 4, protect the collector, to extend battery life. Such as: to prevent collector corrosion, oxidation; increase the surface tension of the collector, and enhance the easy coating properties of the collector; can replace the higher cost of the etching foil or use a thinner foil to replace the original standard foil.
