Global sealing supplier Freudenberg Sealing Technologies is showcasing its automotive battery life cycle solutions — including three new innovations — at the 2024 Battery Show. At its booth, company will demonstrate its innovative solutions aimed at addressing several crucial areas in the life cycle of a battery, including cell manufacturing, module and battery systems development, and battery system vehicle integration. During the show, Freudenberg Sealing Technologies will introduce three unique new products in its battery product family – advanced thermal barriers, prismatic battery cell caps, and prismatic envelopes.
Freudenberg Sealing Technologies’ Battery Protective Covers and Mats serve as thermal barriers, designed to contain thermal runaway and prevent thermal propagation throughout the battery. These thermal barriers are crafted from unique materials that withstand high-temperature venting gases, endure abrasive conditions, and offer electrical insulation. Leveraging their materials expertise, and extensive experience in high-volume automotive manufacturing, the company develops solutions tailored to meet customers’ precise specifications.
In 2023, Freudenberg Sealing Technologies also introduced 3D thermal barriers made of high-temperature resistance plastics and elastomers that are used to shield and protect critical components during thermal runaway events. Like the new battery protective covers and mats, the 3D thermal barriers feature customizable geometries suitable for various positions within the battery.
Freudenberg Sealing Technologies’ new battery cell cap design, with an elastomeric sealing solution for prismatic and cylindrical battery cell manufacturers, improves performance and safety; resists short-term, high-temperate load; and adheres to environmental regulations. These custom-designed cell caps have been developed in collaboration with cell manufacturers and are manufactured on site for the local market with the lowest possible carbon footprint, and in accordance with automotive standards.
The company has also designed a drop-in cell envelope solution that optimizes battery performance. Freudenberg’s new design — which consists of innovative nonwoven materials that wrap the cell stack films — underscores the company’s commitment to innovation, as well as enables efficiency, durability, and performance in cell manufacturing.
“These products will help shape the future adoption of developing propulsion systems, ranging from passenger vehicles to trucks and buses,” said Marco Sutter, Global Market Segment Manager, Automotive, Freudenberg Sealing Technologies. “We look forward to engaging with existing and potential new customers at the Battery Show to demonstrate how our innovations offer reliable and superior performance.”
Other product innovations will also be on display at Freudenberg Sealing Technology’s booth, as well as several sealing innovations, such as busbar flame protection and sealing solutions, gaskets, heatshield products, and the DIAvent® intelligent pressure compensation family of elements.
