Battery Aluminum Foil Manufacturers

Battery aluminum foil manufacturers offer high quality 0.001-0.005 aluminum foil with 1060/1235 alloy O H14, H18 temper. Aluminum foil is the key material in the positive electrode of lithium batteries. Aluminum foil is not only the carrier of the negative electrode active material in the lithium ion battery, but also the collector and conductor of negative electrode electrons. Therefore, it has special technical requirements, that is, it must have good electrical conductivity. The surface of battery aluminum foil can be evenly coated with negative electrode material without falling off, and has good corrosion resistance. In order to ensure that the negative electrode material coated on the electrolytic copper foil does not fall off, a suitable binder must be added during preparation.

Advantages of battery aluminum foil manufacturers in lithium battery applications: inhibit battery polarization, reduce thermal effects, improve rate performance; reduce battery internal resistance, and significantly reduce the dynamic internal resistance increase in the cycle process. Improve consistency and increase battery cycle life; improve activity the adhesion of the substance and the current collector reduces the manufacturing cost of the pole piece. Protects the current collector from corrosion by the electrolyte; improves the processing performance of lithium iron phosphate and lithium titanate materials.

The performance advantages of battery aluminum foil manufacturers: significantly improve the consistency of the battery pack, greatly reduce the battery composition cost; improve the adhesion of the active material and the current collector, the material is soft, easy to process, reduce the manufacturing cost of the pole piece; reduce the polarization, increase the magnification He grams of capacity, improve battery performance; protect the current collector, extend battery life.
