The speakers began by explaining the basics of battery safety. They showed how thermal processes influence service life and what role the composition and quality of the materials used play in this. Participants gained a clear understanding of why even small changes in the material structure can have a significant impact on safety behavior. 

Another focus was on battery aging. Based on current research results, the speakers explained which mechanisms contribute to degradation, how this affects performance, and in which cases aging reduces safety. The presentation made it clear that safety and aging are closely linked and must therefore be evaluated together. 

The discussion of critical conditions such as thermal runaway was of great importance. The speakers showed how such conditions can be detected at an early stage and what prevention strategies are necessary. It became clear how essential a deep understanding of the thermal interactions inside a cell is. 

A central methodological element of the webinar was thermal analysis using calorimetry. Participants were given an overview of various measurement approaches, including application under realistic and extreme conditions. Particular emphasis was placed on the Accelerating Rate Calorimeter (ARC) as a reliable tool for safety assessment of cells of various sizes. The examples showed how ARC data is used to systematically identify risks and support safety-related decisions. 

The webinar also looked beyond lithium-ion systems. The speakers explained how the same methods can be used to investigate new technologies such as sodium-ion batteries and what special features these systems have. 

Practical examples from test scenarios and real-world applications rounded off the event. Participants were able to understand how calorimetry is used to evaluate and continuously improve the safety of energy storage systems. 

With this webinar, the DGM offered a precise and scientifically sound event that clearly highlighted the relevance of materials science for battery safety and provided participants with valuable insights into research, practice, and evaluation techniques.
