Battery Selection Tutorial Course 2/3: Beyond the Standards: Device-Specific Testing
After choosing your cell and manufacturer (Part 1 of this series), most likely, they will have passed the tests of various standards organizations. However, depending on your operating environment, you may need to go above and beyond the baseline to ensure your product operates as intended. This webinar is Part 2 in a three-part series and will review a variety of factors to consider in your device-specific testing, including designing tests to predict the outcomes of various user-abuse scenarios, understanding the mechanisms of gas generation, capacity retention based on different voltage windows, and what happens if you need to cycle your cells outside of their operating range (outside in an Arizona summer or Minnesota winter, for example).
This webinar will focus on the following key topics:
• User-abuse scenarios to prevent against
• Causes and effects of various gas generation mechanisms
• Voltage limits

Advanced Techniques For Addressing Issues in Battery Safety and Performance Using Adiabatic Calorimetry
FREE Webinar – THT is a proud sponsor of this event.
Adiabatic calorimetry is a widely utilized technique within the field of battery safety research. The method has been adapted from the chemical industry to address a significant range of safety and performance tests on battery components, cells and even modules.
Although a number of different battery tests may be employed using the ARC, interpretation of results is not always straightforward. Some of the principles which apply to ARC chemical testing do not translate directly to battery testing due to the variable nature of samples.
This presentation describes both the advantages and limitations of ARC testing on batteries and how the ARC test can be adapted to address different questions in battery research as well as quality control.
This webinar will focus on the following key topics:
• The principles of adiabatic calorimetry (ARC)
• How calorimetry can be used in battery testing
• What we learn from battery testing by calorimetry
• Pressure measurement and gas collection during thermal runaway
• Advanced testing techniques in adiabatic battery calorimetry

Battery Ageing – How Modeling is Used to Predict Battery Life
Battery modeling and simulation makes it possible to analyze multiple operating conditions and design parameters for batteries and other electrochemical systems and processes. By developing mathematical models you can begin to understand the interaction of electrochemical and chemical processes in the battery and how these processes affect the performance and life of the battery.
In this presentation, we will take a look at the benefits of modeling and simulation in the design, selection, and operation of a lithium-ion battery. We will especially take a look at how modeling can be used together with testing. These results provide manufacturers and application experts with the data to not only predict battery life but to analyze the implications of design parameters and operating conditions to better understand the limitation of the battery.
This webinar will focus on the following key topics:
• Benefits of modeling and simulations in the design, selection, and operation of a lithium-ion battery
• Implications of design parameters and operating conditions with respect to experimental observations of battery performance, aging, and battery safety
• How battery modeling can be used together with testing

Avoid Battery Explosions and Fires – With Right Data and Better Designs
Modern Li Ion batteries contain hazardous chemicals and heat up during use – this combination always has the potential to cause fires and explosions. This presentation will focus on improving the understanding of how such incidents occur, what can be done to avoid them and how the risk can be minimized during early stage design.
The solution lies in knowledge of the heat generation rate during normal use, and information about safe boundaries such as temperature, discharge rate & overcharge in realistic situations that represent actual conditions of use. Data from commercial batteries of different types, including videos of batteries undergoing thermal runaway, 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 and explosions occur
• How to design safer batteries through 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 generation
