Advanced Thermal & Electrical Insulation Systems

Battery Electric Vehicles (BEVs) are an important part of our future mobility. Oerlikon’s battery safety solutions for high performance Lithium-ion cells limit the impact of thermal runaway and minimize the risk of passenger injury and severe vehicle damage in the event of thermal propagation.

Our decades long expertise in materials innovation and robust automotive design experience enables us to engineer high-performance customized thermal insulation systems for all safety requirements and battery types in the market. Our safety components for BEVs - revolutionary heat shields, gas guidance systems, and cell separators – set new safety standards.

  • Temperature Resistant up to 1,400 °C
  • Electrical Insulation up to 18kV
  • Enables Zero TP & Limp-home driving mode
  • ESG compliant materials (mica free & non-petroleum-based)
  • UL94 V0
