Innovative Flame Protection for Electric Vehicles
As electric vehicles (EVs) continue to dominate the automotive industry, ensuring battery safety has become a critical concern. One major challenge is preventing fire hazards caused by thermal runaway in lithium-ion batteries. To address this, Autoneum has introduced E-Fiber flame shields, an advanced, mica-free solution designed to enhance fire protection and electrical insulation within EV battery housings. Unlike conventional mineral-based shields, E-Fiber offers superior heat resistance, lightweight construction, and enhanced mechanical durability. This innovative technology significantly improves passenger safety while also providing manufacturers with a cost-effective alternative.
Superior Performance Over Traditional Flame Shields
E-Fiber flame shields stand out due to their ability to endure extreme conditions, including high temperatures of up to 1400°C, intense gas pressure, and hot particle abrasion. Unlike heavy and brittle mica-based shields, E-Fiber’s composite material—made from reinforcing fibers and resin—ensures better strength, stability, and design flexibility. Manufacturers can mold the material into complex 3D shapes to optimize battery coverage and integrate additional safety functions, such as redirecting hot gases away from the battery. Additionally, these shields contribute to the electrical insulation of the battery system, further improving its overall safety and efficiency.
A Safer, More Sustainable Future for EVs
E-Fiber flame shields offer a geometrically adaptable, lightweight, and compliance-safe alternative to traditional flame shields. They can be installed between the battery cells and vehicle floor, reducing risks associated with thermal runaway. Unlike mica-based products, which raise concerns over responsible sourcing, E-Fiber is entirely risk-free from a compliance perspective. The technology has already been validated through rigorous battery tests and is currently in pre-development with various European manufacturers. As the demand for EVs continues to surge, E-Fiber flame shields pave the way for safer and more efficient battery protection solutions.
