Constellium signed a long-term agreement with Lotte Infracell, a subsidary of Lotte Aluminium, a leading provider of aluminum solutions, to supply foilstock for Lotte’s battery foil applications in Europe. This partnership highlights Constellium’s commitment to the growing electric vehicle (EV) market and its strategic focus on advanced automotive aluminum solutions.

Lotte currently has two battery cell product lines: cathode foils and foils for puch cells.

Under this agreement, Constellium will supply high-quality foilstock from its Singen site in Germany. With Lotte Infracell’s financial support, Constellium is planning to invest around €30 million in new finishing lines at its Singen facility to enhance production capacity, creating around 20 new jobs in the process. This strategic investment is expected to further cement Constellium Singen’s position as a key player in the aluminum automotive specialties market.

Aluminium’s lighter weight, conductivity, chemical stability, and lower cost provide a balanced combination of properties that are particularly advantageous for the large-scale production of batteries for electric vehicles.
