Skogar® HT thermal barrier, an ultra-thin blanket made of silica aerogel and high-performance synthetic fibers, will prevent thermal runaway propagation for Lilium eVTOL battery packs.
February 28, 2024 – Enersens (Rochetoirin, France) has been selected by Lilium (Munich,
Germany) as a supplier of its Advanced Thermal Barrier Solution for Lilium’s electric Vertical
Takeoff and Landing (eVTOL) aircraft. As part of the multi-year contract, Enersens will supply its Skogar® blanket that will prevent thermal runaway from spreading inside battery packs, and ensure Lilium can deliver the right combination of high performance and safety for its battery pack.
Enersens’ product range includes ultra-thin blankets (starting at 0.5 millimeter thickness) with the lowest thermal conductivity on the market (as low as 0.012 W/(m.K)) and excellent flame resistance (up to 1300°C), while being capable of withstanding high compressive stresses.
Based on silica aerogel and manufactured via an innovative and strongly patented process,
Skogar® blankets are best-in-class for thermal insulation while being non-flammable, non-toxic and made from sustainable materials. They are a perfect solution when top performance is required within a constrained volume. Inter-cells insulation within a battery pack is one of the key applications where Skogar® out-performs competitor products.
Leveraging 12+ years of R&D, Enersens is a recognized leader in high performance silica aerogel solutions. Its focus is now on ramping up production capacity for Skogar® in order to meet the strong interest from clients in automotive, aerospace, urban mobility and small electronics industries.
“We are proud to have the most efficient thermal barrier on the market.
We are delighted to have been chosen by Lilium and are keen to continue
working with their team to supply them with the best solutions, at a
competitive price,” said Denery Fenouil, CEO of Enersens.
“We are impressed with the solution provided
by Enersens. From a safety and performance
perspective, aerogel-based insulation is a key
component of our battery pack that will
support us in meeting the highest safety
standards required for certification, with entry
into service of the Lilium Jet targeted for 2026,”
remarked Martin Schuebel, Lilium Senior Vice President Procurement.
