Li-ion Battery Thermal Runaway Solution

As lithium batteries are increasingly adopted in electric vehicles and the renewable energy sector, their benefits in clean energy and mobility are evident. However, with large-scale usage comes heightened safety concerns—particularly the risk of battery thermal runaway, a dangerous chain reaction that can lead to fires and explosions.


To address this, the latest UL9540A test method sets stringent fire safety standards for battery energy storage systems. It focuses on evaluating the fire propagation risk of thermal runaway events within energy storage systems, pushing manufacturers to adopt more robust thermal and fire protection measures.

AUWIN CMC has responded to this challenge with the development of high-performance fireproof and thermal insulation materials such as CermiFlex Aerogel, Microporous pad, Endothermic mat . These advanced materials are designed for integration at multiple levels of the battery system—including the battery cell, battery module, battery pack, and even within full energy storage containers ( BESS containers).

By effectively isolating thermally unstable units, these materials significantly slow down or prevent the spread of thermal runaway. This containment provides critical time for fire suppression efforts and enhances overall system safety.

AUWIN’s innovations mark a vital step toward safer, UL9540A-compliant battery storage and EV applications, offering reliable solutions for a sustainable energy future.
