What is aluminum plastic film & why is it important?

The aluminum plastic film is a crucial material in the lithium battery industry chain’s upstream packaging, representing 10-20% of total material cost for pouch batteries.

Can aluminum/polymer hybrid film be used for lithium-ion batteries?

The use of aluminum/polymer hybrid (Al/polymer) film as the package materials of lithium-ion batteries (LIBs) has been extensively investigated in various studies [1,2]. They limited the measurement of the properties only to the composite level, not layered properties.

Is aluminum/polymer hybrid a good package material for lithium-ion batteries?

In particular, the breakdown strength of PFA-300% film was significantly enhanced through high-temperature monoaxial stretching. The use of aluminum/polymer hybrid (Al/polymer) film as the package materials of lithium-ion batteries (LIBs) has been extensively investigated in various studies [1,2].

What is aluminum plastic film?

The aluminum plastic composite film, referred to as aluminum plastic film, is a composite flexible packaging shell material used to package lithium-ion batteries and is often used in soft pack batteries and blade batteries.

What are the three layers of aluminum plastic film?

The aluminum plastic film must be constructed of three layers of materials held together with adhesives in order for it to have the aforementioned properties. The structure is the outer resistance layer, the barrier layer, and the heat sealing layer from the outside to the inside.

What materials are used in a lithium battery?

Polypropylene (PP) is used as a heat-sealing material; an Al sheet is employed to protect the interior from moisture and light, and polyamide (PA) or polyethylene terephthalate (PET) provides mechanical stability and durability. The multilayered LIB pouch is a representative composite material used by battery manufacturers.
