Battery cathode foil

Thin gauge aluminium foil for lithium ion batteries

High performance, no compromises

Featuring a low carbon footprint and light weight combined with high strength and elongation properties, our cathode foil material offers the ultimate combination of performance and sustainability – the perfect choice for battery cell production.

Global reach

Our production sites in Finspång (Sweden), Shanghai (China) and Newport (Arkansas, USA) have production capabilities of rolling and slitting thin gauge foil products. With global reach and strong aluminium material expertise, we are your partner for reliable supply of battery foil from pilot line to gigafactory scale.

All sites are equipped with full production lines from casting to hot rolling, cold rolling and slitting. This enables us to maintain full control of the production process from metal to finished product, and allows for recycling of materials.
