Automotive Battery Solutions

Constellium provides a comprehensive portfolio of rolled and extrusion-based aluminum solutions engineered to meet the evolving needs of battery systems, from foils and cell connectors to thermal management and enclosure materials and components. Our solutions are designed to optimize performance, improve safety, and support scalable, sustainable battery designs across electric mobility and energy storage applications.

Constellium’s aluminum solutions combine strength, crash resistance, and thermal performance to protect and cool EV battery systems. We offer rolled and extruded-based products – including 3xxx, 5xxx, and 6xxx series alloys – for battery enclosures. We offer solutions for fully structural closures as well as the high-volume production friendly cell-to-pack design. 

To achieve fast charging and fast acceleration, batteries need to be actively cooled. With five times the thermal conductivity of steel, aluminum enables better temperature regulation, longer battery life, and optimal charging speed. Constellium is a trusted supplier for leading EV platforms, with our solutions covering different designs of cooling plates based on extrusions or clad brazing sheet.

Constellium’s aluminum products for busbars and module connectors combine electrical efficiency with excellent surface and forming characteristics. Our solutions also offer good corrosion resistance, weldability, and the best-in-class compromise of conductivity and strength. A smart, lightweight alternative to copper – engineered for both performance and processability.

Constellium’s aluminum solutions are tailored for prismatic cell housings, offering high strength, corrosion resistance, design flexibility, and excellent weldability. Compatible with multiple manufacturing processes and adaptable to diverse geometries, our materials help meet the industry’s most demanding structural and sustainability requirements.

Constellium supplies high quality foilstock for battery cathode foil applications. Aluminum'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. Constellium’s premium quality solutions are well-suited to meet the demands of this dynamic market, providing superior performance and contributing to the overall safety and sustainability of electric vehicles.
