China battery aluminum foil manufacturers – Haomei can supply 1060, 1070, 1100, 1235 and 8021 battery aluminum foil applied in lithium battery shell. The most common used grade are 8021 and 1060 aluminum foil. The thickness is 0.006-0.2mm, the temper are O, H12, H14, H24 H16, H18 and H19, the width is 100mm-1500mm.
The application advantages of aluminum foil for battery shell are:
1. Suppress battery polarization, reduce thermal effects, and improve rate performance;
2. Reduce the internal resistance of the battery and significantly reduce the dynamic internal resistance increase of the cycle;
3. Battery aluminum foil can improve consistency and increase battery cycle life;
4. Improve the adhesion between the active material and the current collector, and reduce the manufacturing cost of the pole piece;
5. Protect the current collector from corrosion by the electrolyte;
6. Improve the processing properties of lithium iron phosphate and lithium titanate materials.
The aluminum foil for lithium battery produced by china battery aluminum foil manufacturers through the imported high precision rolling mill with on-line plate roller and Siemens control system. The surface of the battery aluminum foil is uniform, clean, plate shape is flat, and there is no obvious roll mark, pitting, pinhole and corrosion trace. The battery aluminum foil processed by Haomei is well received by the major manufacturers in the lithium battery manufacturing industry.
