Aluminum foil is a kind of aluminum rolled material. Aluminum products with a thickness of less than 0.2mm are usually called aluminum foil. It is an aluminum product with the most processing steps, the smallest thickness, and the greatest difficulty. Aluminum foil can be divided into four main types according to its use: packaging foil, air conditioning foil, electronic foil, and battery aluminum foil.
The positive electrode consists of a positive current collector, a high-temperature tape, a positive electrode matrix and a positive electrode material. The positive current collector is an alloy foil of about 0.1mm such as 1070, 1060, 1235, 1230, 1100, 8011, 1N30, 3003, etc. Among them, 1235, 1070, 1100, and 3003 alloys are used more because they have high strength. The positive electrode matrix is an aluminum foil of about 0.016mm thick.
3003 aluminum foil belongs to the aluminum-manganese alloy series of aluminum foil products. Its strength is higher than that of 1 series aluminum foil, and 10% higher than that of 1100 aluminum foil and 1060 aluminum foil. 3003 aluminum foil has good plasticity and processability, and can be easily processed into various shapes and sizes to meet the needs of different industries.
Besides using in the lithium batery, the power battery shell is laso made of 3003 aluminum foil, which is impact-resistant, not easy to break and leak, and can meet the strength and rigidity requirements of the power battery shell. The aluminum alloy has low density and light weight, which can reduce the weight of the battery, increase the battery capacity density, and make the battery work stably.
Driven by new energy vehicles and energy storage, global demand for battery foil is expected to reach 740,000 tons in 2025, with a compound annual growth rate of 37%. The price of battery foil is determined by "aluminum price + processing fee". At present, the thickness of battery foil is between 8-15μm, and the mainstream thickness in overseas electric power batteries and energy storage fields is 15μm.
The aluminum foil batttery price is affected by many factors: 1) fluctuations in the price of raw material aluminum; 2) technical added value (processing fee); 3) different companies have different product cost control capabilities and technical quality, and their prices are also different.
