Industrial Aluminum Foil Roll

Industrial aluminum foil roll have wide application such as cable, electrolytic capacitor, battery, air conditioner and so on. Among them the battery aluminum foil is a promising product for the new energy automobile popularize, the lithium battery of automobile use aluminum foil as the raw material, for industrial aluminum foil have many advantages.

Properties of industrial aluminum foil roll:

1, Significantly improve the consistency of the battery pack and greatly reduce the battery composition cost. Such as: significantly reduce the dynamic internal resistance increase of the battery cell; improve the pressure difference consistency of the battery pack; extend the life of the battery pack; greatly reduce the battery composition cost.

2, Improve the adhesive force between the active material and the current collector, and reduce the manufacturing cost of the pole piece. Such as: Industrial aluminum foil improve the adhesion of the positive electrode material and the collector using the aqueous system; improve the adhesion of the nano- or sub-micron-scale positive electrode material and the collector; improve the adhesion of lithium titanate or other high-capacity negative electrode materials and the collector; Improve the pass rate of pole pieces and reduce the cost of pole pieces.

3, Reduce polarization, increase magnification and gram capacity, and 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 polarization and improving power performance.

4, Protect the current collector and prolong the service life of the battery. Such as: industrial aluminum foil roll prevent the current collector from corrosion and oxidation; increase the surface tension of the current collector and enhance the easy coating performance of the current collector; it can replace the higher cost etching aluminum foil or replace the original standard foil with a thinner aluminum foil.
