Electric mobility in the automotive sector – Our solutions for a better environment

Precision down to the finest detail: We produce high-quality material solutions for automobile and battery manufacturers. Our semi-finished products are found in many interior and exterior parts of modern vehicles ensuring they are lighter and cause fewer emissions. 

Varied requirements – optimal solutions Our rolled aluminium products for vehicles

Reliable solutions are needed to cope with major changes in the energy and transportation sectors, and to support sustainable infrastructure. At Speira we have the ability to provide such solutions, thanks to the versatile properties of our material: We produce rolled aluminium products for many different applications. Our material solutions enable our customers to produce future-proof vehicles with low-maintenance and lightweight components.

Our product portfolio includes a wide range of solutions for use in body-in-white, battery casings and contact systems.

Our aim is also to make internal processes as effective, secure and sustainable as possible - which is why we continuously analyze and record our own work.

Battery electrode foils

Lithium-ion batteries are ideal for our cellphones and electric vehicles because they are powerful, reliable, and suited to a wide range of applications. 

Benefit: Foil Special mixture for the rolling process

Benefits of electrode foil
  • Good flatness values and low porosity - for ideal further processing
  • Available in a wide range of thicknesses
  • Provides exceptional conductivity

Ensures full storage capacity Our electrode foils for lithium-ion batteries

At Speira, we have been involved in the production of primary materials for this type of battery cell for several years. Due to the highest quality requirements, our primary materials meet demanding automotive industry standards - and are IATF-certified.

We're also proud to be a reliable supplier to one of the world's largest battery producers. But our sights are set even higher: because it's our clear goal to manufacture effectively on multiple production lines.

Our electrode foil serves as a carrier material for the active mass of a lithium-ion battery, onto which the active material can be applied very easily. Good flatness values and low porosity mean that our customers can steadily increase the efficiency of their downstream processing. If required, we can adapt the surface tension to ideally fit the specific customer project.

We also provide foils with glossy surfaces: in the classic thickness range of 12-15 micrometers, we are happy to accommodate customer-specific requirements. Our pre-material always combines high tensile strength with good elongation stretching. Our high purity 1XXX and 8XXX alloys deliver outstanding conductivity that meets the highest standards.

 

Cell and module housings Safety meets Performance

High-quality material from the housing

Benefits of Cell and module housings
  • Good conductivity, high malleability
  • Optimally suited for further processing
  • Enables lightweight and energy-saving vehicles

Our aluminium is the multi-functional protective layer for your battery system

High-powered batteries must be protected in a reliable manner. This requires a material that can be formed into complex shapes. Our aluminium materials for cell and module housings not only combine high safety with lightweight construction - they also enable improved thermal management due to their excellent thermal conductivity, increased service life thanks to a more homogeneous temperature distribution in the cell, and faster charging thanks to the efficient cooling of your battery system. As a volume supplier to the largest battery manufacturer in Europe, we know what's important, and are happy to work with you to develop a strong and reliable aluminium solution.

Busbars & contact systems Reliable connection – efficient conductivity

Our material solutions for busbars and contact systems

Keep the power on with our aluminium solutions for contact systems and busbars. Our materials enable a balancing act between high specific conductivity, lightweight potential, and minimal contact resistance. And we don't need to shy away from comparisons with copper materials here: Fast-growing markets demand reliable performance on a top level, with low costs at the same time - here, our aluminium clearly has the edge. Contact us and we'll find the ideal solution for your efficient battery system.

Thermal management Always at a comfortable temperature

Thermal management with Speira aluminium for greater driving range and service life

Modern battery systems show optimal performance and service life between approx. 20°C and 40°C. The task of thermal management systems is to maintain this "sweet spot" and to keep the battery at a comfortable operating temperature. Our specially developed materials for heat exchangers in battery applications guarantee sophisticated and efficient thermal management, whether it's during fast charging or out on the road. Thanks to their excellent malleability, adhesive and soldering properties, and ease of further processing, our materials enable tailor-made solutions for every application.

Battery casings Our strongest materials for your safety

We combine crash safety and vehicle performance with robust material solutions

The vehicles of the future are powerful, safe, and efficient. We are paving the way for this with our tailored aluminium alloys for battery casings, combining maximum robustness with the potential for economical lightweight design. Our materials not only protect your battery in the event of a crash - corrosion is also efficiently avoided and the high thermal conductivity of aluminium enables improved thermal management under both hot and cold conditions. In addition, battery boxes made of our materials meet all requirements for electromagnetic compatibility (EMC) as well as water and gas sealing.

Do you need complex geometries and precisely-fitting solutions too? No problem, because our versatile alloys for battery casings are also weldable and can be reformed optimally.
