Aluminum polyester film for lithium batteries is a packaging material for soft-packed lithium batteries. Covers lithium battery packaging film, lithium battery Aluminum polyester film, lithium battery packaging mold, polymer lithium battery aluminum plastic packaging film, polymer battery soft package Aluminum polyester film, aluminum polyester packaging film,Aluminum polyester film, composite film, printing composite roll Film, Aluminum polyester food film, paper aluminum polyester roll film.
The advantages of aluminum polyester film are good deep drawing performance, excellent short-circuit resistance performance, good water barrier performance, better electrolyte resistance and barrier performance, especially in electrolyte corrosion resistance.
The aluminum polyester film can be roughly divided into three layers-the inner layer is the adhesive layer, and polyethylene or polypropylene materials are mostly used for sealing and bonding; the middle layer is aluminum foil, which can prevent the penetration of water vapor from the outside of the battery and prevent the internal The leakage of electrolyte; the outer layer is a protective layer, mostly using high melting point polyester or nylon material, which has strong mechanical properties to prevent external force from damaging the battery and protect the battery.
The research and development of high-quality aluminum polyester film is the key to the successful development of a high-tech product of liquid soft-packaged lithium-ion battery. As the outer shell of the liquid soft-packaged lithium-ion battery, the aluminum-plastic composite film is no longer just a simple outer packaging of the battery, but also constitutes an indispensable and important part of the liquid soft-packaged lithium-ion battery.
Lithium battery aluminum polyester film application industry:
1.Aluminum polyester film can be used for vacuum packaging of mechanical and electrical products, glass packaging, large equipment and precision instruments to prevent oxidation and rusting of products.
2. Aluminum polyester film can be made into flat bags and three-dimensional bags for the packaging of fine chemicals, engineering plastics, pharmaceutical dye intermediates, and adsorbents, which can effectively prevent the product from moisture absorption and agglomeration, oxidation and deterioration, and extend the storage and transportation time.
3. Lithium battery packaging film, lithium battery packaging.
Performance characteristics of aluminum polyester film for lithium battery:
The aluminum polyester film packaging soft-pack lithium battery has the characteristics of good flexibility, flexible shape, good safety performance, and high energy density, so that it can be made into batteries of various shapes and capacities according to product requirements, and is a power supply solution for developers The above provides high design flexibility and adaptability. At present, mainstream digital products and electric vehicles mainly use soft pack lithium batteries.
