Soft-pack lithium battery is another name for polymer battery. It is packaged in aluminum-plastic film in structure. It has the characteristics of small size, light weight, high specific energy and high safety. At most, the pack battery will only burst with air, and will not explode.
Aluminum-plastic film is mainly composed of nylon layer, aluminum foil layer, heat-sealing layer and adhesive for bonding. Aluminum foil is used as the raw material of aluminum-plastic film for soft pack battery, mainly 8021 aluminum foil and 8079 aluminum foil, and the state is O state . Aluminum-plastic film has high barrier properties, good cold stamping formability, puncture resistance, resistance to electrolyte stability, high temperature resistance, insulation, etc. These performance characteristics also determine the high technical requirements of its production process and the harsh standards of raw materials.
8021 aluminum foil has excellent moisture-proof performance, light-shielding and extremely high barrier ability. Non-toxic and tasteless, safe and hygienic. Aluminum foil after compounding, printing and gluing is widely used as packaging material.
8079 aluminum foil is an aluminum foil with high strength, good elongation and stretchability. 8079 aluminum foil not only has the advantages of moisture-proof, air-tight, shading, abrasion-resistant, fragrant, non-toxic and tasteless, but also because of its elegant silver-white luster, it is easy to process beautiful patterns and patterns of various colors, so it is easier favored by people.
With the development of consumer electronics products becoming thinner, smaller, higher performance and multifunctional, higher requirements are put forward for batteries. The demand for pouch batteries is increasing, and the consumption of aluminum foil is also increasing. As a large-scale aluminum foil manufacturer, MC Aluminum produces battery soft pack aluminum foil with good performance, uniform and clean surface, flat pattern, low price and wide range of uses. It ensures the control of export thickness and provides customers with high-quality and satisfactory products.
