AS-PETAF PET Composite Aluminum Foil 240MPa Tensile Strength Battery Current Collector

AS-PETAF PET Composite Aluminum Foil 240MPa Tensile Strength Battery Current Collector

Product Name: PET Composite Aluminum Foil

Model Number:AS-PETAF

Brand Name: AS

Product Origin:China

Product description: Composite aluminum foil is a new-type of battery current collector, which has thinner aluminum film, overall lighter weight, and higher safety during penetration experiment compared to the conventional

The AS-PETAF composite foil combines 8μm ultra-thin PET substrate with 99.35% purity aluminum coating, delivering 240MPa tensile strength and 40MΩ anti-shorting resistance. Ideal for high-energy 4680 cells and solid-state batteries, it reduces thermal runaway risks by 60% vs traditional foils.
