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

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

Maximizing Battery Performance and Reliability for Electric Vehicles and Energy Storage
FREE Webinar – Voltaiq is a proud sponsor of this event.
As automakers and utilities transition away from non-renewable energy sources, batteries have become essential for efficient energy storage and delivery. Companies are working intensely to deliver higher capacity and more robust batteries to power their products, but ad hoc development processes cannot keep pace with the volume of battery data being generated. In addition, understaffed battery development teams are unable to leverage their data to accelerate development or improve production and manufacturing.
In this webinar, we will outline the challenges that the battery industry is facing and how big data analytics can virtually eliminate manual data management and provide powerful capabilities that deliver rapid insights into a battery’s design that dramatically accelerate the development process and results in products with greater performance and reliability.
This webinar will focus on the following key topics:
• Recognizing the challenges and bottlenecks in battery development today
• Automating the battery data collection, data cleaning, and data management process
• Identifying design issues earlier with predictive analytics
• Leveraging metadata to understand the impact of materials, processes and test conditions

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 mechanisms
