As electric vehicles (EVs) become more widespread, ensuring lithium-ion battery safety during collisions is increasingly important. Mechanical impacts can cause internal damage, leading to short circuits, thermal runaway, or explosions. Protective enclosures help reduce deformation, but effective design demands accurate failure predictions. This webinar presents a comprehensive approach for modeling mechanical abusive loads on EV batteries, incorporating experiments, material characterization and the Sahraei Failure Criterion—a universal failure model based on microstructural simulations of the electrode-separator assembly. Model validations will be presented across various cell types and loading scenarios in commercial software such as Ansys LS-Dyna and Altair Radioss. Combined with multi-scale simulations, this framework supports the development of safer, more resilient battery systems for EVs.
This webinar will focus on the following key topics:
• Experimental Methods for Material Characterization
• Multiscale Modeling from Components to Cells and Battery Packs
• Short Circuit Prediction with Sahraei Failure
• Applicability to Pouch, Cylindrical and Prismatic Cells

Beyond Electrochemical Analysis – 2D to 4D Correlation of Microstructure and Chemistry in Li-ion Batteries
Single imaging instruments as well as correlative microscopy workflows have demonstrated some unique abilities to support LIB research beyond electrochemical analysis methods. Light microscopy delivers insights about ablation effects & phase orientations in the active material, while scanning electron microscopy (SEM) reveals information about aging effects, nanometer cracks & the composition of the active material. Combining SEM with in-situ Raman spectroscopy extends the traditional SEM capabilities to organic and inorganic material identification. X-ray microscopy, furthermore, delivers 3D non-destructive imaging of full battery packs and localized high-resolution information, thus allowing the identification of regions of interest within the battery material volume. This presentation will demonstrate the application of these techniques to Li-ion battery research, including examples on anode, cathode, binder, and separator materials.
This webinar will focus on the following key topics:
• Introduction to available microscopic investigation techniques
for Li-ion battery research:
– Light Microscopy
– Scanning Electron Microscopy
– X-ray Microscopy
– Raman Spectroscopy
• Review of recent battery imaging studies in published literature
• Case studies on using correlative microscopy to characterize battery performance & failure mechanismsPresenter

Determination of Battery Safety and Performance Parameters Using Adiabatic and Isothermal Calorimetry
FREE Webinar – Thermal Hazard Technology is a proud sponsor of this event.
This presentation describes two main types of calorimetry which can be used to carry out safety and performance testing on batteries. Isothermal calorimeters allow for direct heat measurement on cells during use, while adiabatic calorimeters can measure heat released from batteries during thermal runaway.
Calorimetry can serve as a quantitative scientific method for evaluation of battery safety but it requires appropriate instrumentation. The principles of operation of both types of calorimeters are described along with specific applications within the field of battery testing.
A combination of both technics allows for detailed thermal characterization of lithium-ion and other rechargeable cells, and differences due to chemistry, cell design, cell age, state of charge and cell size can be evaluated.
This webinar will focus on the following key topics:
• The principles of adiabatic and isothermal calorimetry
• How calorimetry can be used in battery testing
• Parameters established by adiabatic safety testing
• Parameters established by isothermal performance testing
• Pressure measurement and gas collectionPresenter

Understand and Prevent Battery Fires and Explosions – and Avoid Costly Failures Like the Samsung Note 7
Modern batteries (eg Li-Ion) contain hazardous chemicals & they heat up during use: this combination always has the potential to cause fires & explosions. This presentation will focus on improving the understanding of how these incidents occur, what can be done to avoid them & how the risk can be minimized during early stage design.
The Samsung Note 7 phone & Boeing Dreamliner airplane fires are very costly examples of how even large corporations fail to understand the potential fire risk of batteries.
The solution lies in knowledge of heat generation rate during normal use & information about safe boundaries such as temperature, discharge rate & overcharge, in realistic situations that represent actual use conditions. Data from commercial batteries of different types will be used to illustrate these points.
A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.
This webinar will focus on the following key topics:
• Why battery fires & explosions occur
• How to design safer batteries though understanding of heat generation
• Video evidence of batteries under explosive conditions
• How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
• Laboratory instruments suitable for testing and data generationPresenter
