Mingtai Aluminum analysis Al compound packing film aluminum foil

Edit:Mingtai Date: 2019-09-25 16:41
Many people are very curious about the aluminum compound packing film of soft pack lithium-ion batteries. Here, Mingtai Aluminum manufacturer will explain it to you.
Mingtai aluminum aluminum foil manufacturer aluminum compound packing film (also known as aluminum compound packing film) is the outer packaging material of soft pack lithium ion battery. In order to ensure long-term stable operation of the battery, aluminum compound packing film needs to have high barrier property and good Cold stamping formability, puncture resistance, electrolyte stability and insulation. Therefore, the aluminum compound packing film is a high-strength, high-barrier multilayer composite structure composed of a variety of plastics, aluminum foils and adhesives. To meet the performance requirements of soft pack batteries.
Mingtai aluminum aluminum foil manufacturer soft pack battery is made of aluminum foil (8021 aluminum foil 0.04mm thickness) and plastic film, special glue glued together known as aluminum compound packing film, and then Mingtai aluminum aluminum foil (1235 aluminum foil/1060 aluminum foil/1070 pure Aluminum foil 0.012-0.016mm thickness) coated with lithium iron phosphate and lithium manganate ternary materials, made into a soft pack battery core, placed in the finished aluminum compound packing film The battery of the electronic product, to replace more lead-acid batteries, is the lithium battery that everyone talks about.
Mingtai Aluminum 8021 aluminum foil material has good performance extension. The main advantages are commonly used in deep-drawn packaging materials. Due to the special properties of 1235 aluminum foil/1060 aluminum foil/1070 aluminum foil, these aluminum alloy foils are also commonly used in electronic products. Inner core.
Advantages of Mingtai Aluminum 8021 Aluminum Foil as aluminum compound packing film Material
1. Mingtai Aluminum 8021 aluminum foil has high energy density. The average 18650 battery capacity can be about 2200mAh, so the energy density is about 500Wh/L, and the energy density of the polymer battery can be close to 600Wh/L.
2, Mingtai Aluminum 8021 aluminum foil is safe. This problem does not exist in polymer batteries. Even in extreme cases, because the strength of the packaging film is low, as long as the air pressure is slightly higher, it will rupture, and no explosion will occur. The worst case is burning.
Mingtai Aluminum Advantage
Mingtai Aluminum is the top ten enterprise in China's aluminum sheet and foil industry. It is one of the top 500 enterprises in China. It produces 8021 aluminum foil with excellent performance, smooth surface, no cracks, corrosion spots and traces of nitrate. It is well received by the market. In the future, Mingtai Aluminum will continue to strictly control the quality of 8021 aluminum foil products, strive to enhance the influence of corporate brands, enhance customer satisfaction, and create more wealth for customers.
