AIS thermal barrier battery protection chosen for leading Korean EV platform
As EV adoption accelerates, battery safety remains a critical engineering priority. One of the most significant risks is thermal runaway, a chain reaction where heat from a failing lithium-ion cell spreads rapidly to neighbouring cells, potentially leading to fire events that are difficult to control.
A leading Korean Tier-1 automotive supplier required a thermal barrier solution capable of meeting stringent performance requirements while supporting rapid development. AIS provided ContraFlame® S109, an advanced thermal barrier material for a next-generation electric vehicle (EV) battery platform.
The highlights
Proven thermal runaway protection
ContraFlame® S109 demonstrated exceptional performance in preventing and slowing propagation during rigorous testing.
Rapid development
Our in-house battery testing capabilities reduced development time and enabled rapid design validation.
Seamless integration
S109 adapted to the complex battery pack architecture without impacting design or performance.
Solution
AIS provided ContraFlame® S109, a high-performance coated fabric engineered specifically for thermal runaway mitigation in lithium-ion battery systems.
The material provides the thermal barrier capabilities the customer required, to isolate failing cells and limit heat transfer to adjacent components. During validation testing, S109 demonstrated exceptional capability in delaying and preventing propagation under extreme conditions.
Results
AIS secured supplier nomination for a next-generation EV battery platform, with ContraFlame® S109 validated through extensive testing for its ability to prevent and delay thermal runaway propagation. The material delivered reliable thermal barrier performance under demanding conditions, supporting critical battery safety requirements.
ContraFlame® S109 was integrated into the customers complex battery architecture without requiring significant engineering modification, enabling efficient implementation. AIS' in-house testing capabilities and rapid sampling accelerated the development and validation process, providing measurable value to the customer. This programme further strengthens AIS' position as a trusted supplier of advanced battery safety materials within the global EV supply chain, particularly within the Korean automotive market.
