In the global push towards cleaner energy and e-mobility, battery performance and sustainability are central to innovation. Yet the efficiency, safety, and recyclability of battery components continue to present major challenges.
Freudenbergt Sealing Technologies (FST) is addressing these head-on by focusing on battery cell caps (BCCs) – a critical component in next-generation energy storage systems, particularly in electric vehicles. With deep expertise in advanced materials, sealing, and mass production, FST is uniquely positioned to become a key player in the structural components of battery cells.
Engineering performance through material innovation
Battery cell caps play a crucial role in thermal management, pressure regulation, and overall battery safety. Drawing on decades of experience in engineered plastics, rubbers, and metals, FST combines precision engineering with proven manufacturing know-how to deliver materials that enhance efficiency, durability, and reliability across a range of applications.
Each project demands the production of tens of millions of multi-component parts annually, all requiring stacking, crimping, welding, and inspection with consistent precision. To meet these demands, the FST Adaptive Technology Group is developing a highly automated production line, designed to fulfill even the most stringent customer specifications.
Solving sealing and durability challenges
Battery caps must remain sealed against gases and liquids across a wide range of temperatures, deformations, and chemical exposures. This is a challenge well-aligned with FST’s core strengths in material science and sealing technologies. The company’s expertise ensures robust, reliable solutions even in the most demanding battery environments.
“At FST, we see every challenge in battery cell cap development as an opportunity to innovate”, Maurizio Buro, Global Technical Director at Dynamic Sealing Division, says. “By leveraging our expertise in advanced materials and automated production, we’re not just meeting industry demands, we are setting new standards for safety, efficiency, and sustainability in energy storage.”
To guarantee consistent quality, the Battery Cell Caps Incubator Group is actively exploring non-destructive testing technologies for full integration into high-volume production. This focus on innovation ensures the highest levels of safety, performance, and traceability.
Sustainability at the core
Sustainability is embedded into FST’s approach to material development. From recyclable, lightweight alloys to engineered plastics that minimize hazardous waste, the company is committed to reducing the environmental footprint of energy storage solutions—without compromising on performance or reliability.
Decades of know-how, focused on the future
With decades of experience in metal forming and advanced materials including plastics, rubber and foams, FST has partnered with leading battery manufacturers to co-develop next-generation solutions that extend battery life, improve energy efficiency, and meet evolving global sustainability standards.
Powering progress together
The future of energy storage depends on structural components that are high-performing, scalable, and sustainable, and FST has what it takes to make improvements in all of these aspects. By transforming its extensive material and engineering expertise into comprehensive solutions, FST is driving progress and helping to power a cleaner, more efficient world.
