Safety remains a top concern with the development of new battery chemistries to prevent harm to the consumer and the end-product itself. Safety is especially important in applications such as electric vehicles and other uses in which batteries are more susceptible to external factors that could affect performance, such as a mechanical impact or changing environmental conditions. In particular, lithium-ion batteries may trigger exothermic side reactions and overheat, potentially leading to thermal runaway and combustion with catastrophic results.

Battery developers and manufacturers ensure battery safety using material characterization to understand their batteries’ key thermal and structural properties. This eBook offers foundational overviews and test examples demonstrating 5 essential thermal analysis and mechanical analysis techniques behind cutting-edge battery development and safety testing. After reading this eBook, you’ll be able to answer critical questions about your batteries’ safety:

• At what temperatures do degradation and thermal runaway begin?
• How will my materials’ strength change with temperature and force?
• What is the deformation and rupture temperature of my separator?
• How can I improve low-temperature performance?

The studies in this eBook will enable researchers to optimize their battery formulations for end-use safety as well as efficient, cost-effective processing.
