Battery Electrode Film

Combining Aluminium and Copper metallised PET polymer films in battery electrode manufacture can potentially offer several benefits due to their unique properties and synergistic effects.

The Aluminum layer provides a lightweight and cost-effective conductive network, while the copper layer offers higher electrical conductivity. This combination ensures efficient electron transfer during charge and discharge processes within the battery, resulting in enhanced battery performance and reduced internal resistance.

The vacuum metallised metal layers are then subsequently deposited with electrolytic copper, to build a layer stack that is suitable for the demands of battery electrode substrate.

PET polymer films are inherently lightweight, and the addition of thin aluminium and copper layers creates a lighter weight electrode substrate compared to traditional 100% copper foil.

This weight reduction contributes to improved energy density, making the battery more suitable for portable devices, electric vehicles, and other applications where lightweight and compact designs are crucial.

Aluminium and Copper metallised PET polymer films, offer excellent mechanical stability and flexibility compared to traditional 100% copper foil. They serve as strong and durable supports for the active electrode materials, preventing electrode ripping and failure during R2R manufacture and degradation during repeated charge-discharge cycles.
