Pure Copper Metallization

Copper foil is well established in the Li-ion battery industry, but cost and safety constraints drive the search for alternatives. Foils are challenging to process and typically increase the risk of thermal runaway, resulting in combustion. In addition, the extra weight of foil compared to PET is often a sensitive issue.

 

Avery Dennison Hanita offers an ultra-thin PET film featuring a highly conductive copper layer, presenting a viable solution. This PET film can be coated with copper on one or both sides, exhibiting exceptional metal adhesion. As a cost-effective substitute for copper foil in EV batteries, this film provides a safer, more manageable, and lighter option, potentially increasing driving range.
