The presentation focuses on the development of advanced testing methodologies for battery cells, addressing both mechanical and thermal aspects of performance. It explores the design and execution of swelling tests to quantify dimensional changes under thermal and mechanical stress, as well as the influence of cell construction and pre-force application on structural stability. The work also investigates optimal pre-load conditions to enhance safety, efficiency, and cycle life, alongside the evaluation of suitable materials for mechanical support. Additionally, thermal characterization, including heat conductivity and calorimetry tests, is used to better understand heat dissipation behavior and inform thermal management strategies in battery system design.

In this session, you will learn more about:

• The methodology behind swelling and pre-force testing
• Material and mechanical optimization for cell integrity
• Thermal testing and calorimetric evaluation techniques
• Data-driven approaches for performance validation
