Freudenberg Sealing Technologies to launch customized 3D safety components for batteries

To improve the efficiency of electric vehicles, OEMs are working to increase range and shorten charging times. However, when developing lithium-ion batteries with a higher energy density there is a risk of thermal runaway. To overcome this, Freudenberg Sealing Technologies has developed thermal barriers to slow down – or even stop – thermal runaway by increasing thermal propagation resistance.

“What is completely new is that the thermal barriers are now also available in customized, flexible 3D geometries, which makes it possible to use them in various positions within the battery and allows for integration of additional components,” said Andrew Espinoza, global vice president of technology in the Oil Seals Powertrain & Driveline Division at Freudenberg Sealing Technologies.
