Battery aluminum foil is one of the base materials for new energy vehicle lithium batteries. Generally, the lithium-ion battery industry uses rolled aluminum foil as the positive electrode collector. The main constituent materials of lithium-ion batteries include electrolyte, separator materials, positive and negative electrode materials, etc. The positive electrode includes a current collector composed of aluminum foil and lithium cobaltate or lithium iron phosphate. At present, general battery foil products generally require a strength of ≧180Mpa, and it is pure aluminum alloy, which means that battery foil is a product that has extremely strict requirements on the base material of aluminum foil, and battery foil requires the thinnest thickness and highest strength, the highest surface dyne value, the smallest thickness difference, the best plate shape, and the cleanest surface.
1235 aluminum foil, 1060 aluminum foil are widely used on aluminum foil for lithium-ion batteries. The product has uniform surface color, clean, flat plate shape, no obvious oil stains; strength > 180Mpa, elongation > 1.5%, wettability > 32 dyne, can effectively Improve the adhesion between the active material and the current collector, and reduce the manufacturing cost.
|Alloy||Temper||Thickness (mm)||Width (mm)||Length (mm)|
|1060||O, H14, H18||0.016-0.2||100-1600||C|

The aluminum content of 1070 aluminum foil is more than 99.7%. It is an aluminum foil material with good heat dissipation, electrical conductivity and thermal conductivity. It is suitable for making gaskets and capacitors from aluminum foil, especially in electronic components because of its good conductivity.
The aluminum content of 1235 aluminum foil is more than 99.35%. It is also a kind of pure aluminum foil. It has good anti-rust properties, formability, weldability, and excellent mechanical properties such as elongation and tensile strength. It is widely used In wire and cable, adhesive tape, battery foil.
8006 aluminum foil has high strength, good elongation and rolling performance. The product is smooth and flat, has extremely high moisture-proof, fresh-keeping performance, and is not easy to deform. It is a high-quality material for making lunch boxes and egg tart trays.
