The yearning to explore lakes, seas and oceans and to travel by ship is something that has moved people from time immemorial. The ambition to do so as sustainably as possible and with greater awareness is growing stronger and stronger, however, and bringing together both commercial and private shipbuilders and seafarers. In this context, lower weight, long service life and high recyclability play decisive roles.

As one of the leading providers of material solutions in shipbuilding and transportation, we offer the right solution for an extremely wide range of requirements.

Our VIA Maris products withstand the elements and prove their value through efficient use, corrosion resistance and safety. Set sail with us and discover our cost-effective and sustainable aluminium solutions for shipbuilding.

Aluminium is a highly versatile material providing a multiplicity of great properties, such as high thermal conductivity, lightweight, high formability, strength and recyclability, that are crucial for manufacturing of modern, high-energy lithium ion battery (LIB) cells. While industry takes advantage of these beneficial properties and uses aluminium as the standard material for prismatic and pouch LIB cell housings, the majority of cylindrical cell concepts is still based on nickel-plated steel (NPS). However, with increasing cell sizes, efficient thermal management of the battery cells becomes more important and aluminium cell housings can provide a technical superior solution for cylindrical cells compared to NPS.

This joint study between Speira GmbH and the chair of Production Engineering of E-Mobility Components (PEM) Aachen provides a 4680 cell concept featuring an aluminum cell housing based on a novel material solution for battery cell housings named Speira ION cell. The cell concept was challenged in different 3C fast-charging scenarios using thermal simulation. The simulations reveal significantly improved cooling performance compared to a reference LIB cell with commonly used NPS cell housing.
