Battery cell production is being expanded across Europe, increasing the demands placed on cell components in terms of safety, integration, and scalability. Swoboda is introducing a new solution for e‑mobility and energy storage: the modular Battery Lid Assembly for prismatic cells. The component is used in battery cells, packs, and systems for electric vehicles as well as in other battery‑powered applications, and is tailored to customer specifications.
Flexible configuration, short cycle times
Swoboda’s lids are developed for prismatic cell types and can be customized across a wide range of parameters—from electrode design to the geometry and configuration of the safety vent, all the way to mechanical dimensions. This enables seamless integration into both existing and future cell architectures, regardless of the production site. “With our solutions, we aim to strengthen European battery cell production in particular—while also serving as a reliable development partner internationally,” emphasizes Christian Göser, CSO at Swoboda.
Using state‑of‑the‑art FEM simulations and advanced manufacturing technologies—including laser welding and forming processes—Swoboda meets the highest quality standards while ensuring short cycle times. The Battery Lid Assemblies are available in various form factors and can be adapted to specific customer requirements.

Safe, reliable, and robust
The Battery Lid Assembly provides a pressure‑tight seal for the cell and covers both the anode and cathode sides. An integrated burst‑pressure vent can be added as an option to further enhance system safety.
Swoboda’s Battery Lid Assemblies are individually engineered and dimensioned to meet exact customer requirements. They are made from high‑quality materials such as copper and aluminum, ensuring reliable electrical performance and high durability. The components are designed for operation at temperatures of up to +80 °C, making them suitable for demanding thermal environments. Burst pressure can be flexibly configured between 8 and 14 bar to meet different safety specifications. In addition, all variants are fully qualified for automotive use and therefore suitable for high‑volume production in international battery cell manufacturing.
