ZEEKR EV Battery Thermal Runaway Containment Strategy Using AG-ST-GF Aerogel Sheet

ZEEKR New Energy Vehicles adopts AG-ST-GF Aerogel Glass Fiber Thermal Insulation Sheets as a core battery safety component, prioritizing thermal runaway containment in its premium EV power battery design. In high-density battery packs, the speed of inter-cell heat propagation determines whether a thermal event remains isolated or escalates to full pack failure. When a cell enters thermal runaway, temperatures spike within seconds. Without an effective barrier, adjacent cells ignite in a cascade that overwhelms safety systems. AG-ST-GF installed between cells forms a reliable thermal barrier with 0.020 W/(m·K) conductivity, significantly delaying heat transfer to neighboring cells and extending the critical response window for battery management systems to activate protective measures. Beyond emergency performance, AG-ST-GF reduces steady-state temperature differences between cells during normal operation, improving electrochemical balance across the pack and extending cycle life. Its flexible, slim design fits ZEEKR's compact battery layouts perfectly, maintaining full compatibility with the brand's lightweight development philosophy and high-volume production requirements.
