The goal of WP5 is to develop mechanical solutions for a high-performance solid-state battery system with significantly increased energy density and lower cost. In addition, a major focus is put on an enhancement of safety aspects in case of fire as well as on a significantly lower environmental impact by using eco-friendly materials and improving dismantling.
The mechanical solutions are combined in the development of a novel solid-state battery enclosure and the corresponding cell holder. In this context, specific targets are:

• Innovative mechanical structures for the optimum and safe integration of solid-state cells in the battery system
• Cost-efficient lightweight design and increased energy density using reinforced polymer materials and function integration
• A significant reduction in the carbon footprint of the structural battery system
• Significantly enhanced safety against fire
