The Future of Passive Propagation in Battery Technology – cell, module, pack and ESS.

In modern battery systems, managing the risk of thermal runaway is essential to prevent fire and maintain safety. Passive propagation is an approach that helps control thermal runaway by containing or slowing the spread of excessive heat through the battery cell, module, pack, or energy storage system (ESS), without requiring external intervention. This strategy is increasingly critical as we seek safer, more reliable battery solutions for electric vehicles, stationary energy storage, and other applications.  

TÜV SÜD’s new white paper explores the evolving landscape of passive propagation, offering essential insights and practical guidance for manufacturers and engineers. The paper explains the methods, materials, and design strategies for enhancing passive battery safety, reducing risks, and enhancing product resilience.
