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 collection

Update on Zinc Hybrid Cathode Battery Technology: Lessons Learned from Demo Projects with Major Utilities in US & Europe
With no economical means to store energy, the utility distribution network has typically been overbuilt and continually expanded to serve peak demand, though only a fraction of that infrastructure is used on an average day.
Working closely with utility partners like AEP and Con Edison, Eos Energy Storage has evaluated the economics of battery storage on the distribution system, with compelling results. Using first-hand knowledge of system costs and specifications, it was found that a utility-owned battery system can break even with a conventional T&D upgrade of ~$5M, or less when monetizing available market revenues.
In this webinar, Eos will share an update on commercialization of its zinc hybrid cathode battery technology and share lessons learned from deployments with major utilities in the US and Europe, from initial business case analysis to commissioning a turnkey product.
This webinar will focus on the following key topics:
• Discuss how energy storage can be leveraged as a utility distribution asset and market resource
• Share Eos’s experience in deploying energy storage systems at utility sites in the US and Europe
• Update on performance and path to commercialization for novel zinc hybrid cathode battery technology

Battery Selection Tutorial Course 3/3: Integrating Your Battery Into Your Product – Designing for Worst-Case Scenarios
The last part in Exponent’s three-part series, this webinar will focus on the finished product from the viewpoint of the battery. How can you best protect your battery within your device? Is your battery going to be user-replaceable? If you’re creating multi-cell packs, how should they be separated from (yet still connected to) each other? Should a thermal event occur, how can you prevent that from cascading through the whole pack? This webinar will help to answer many of those questions, and discuss design questions to help safeguard your battery pack throughout its entire lifecycle.
This webinar will focus on the following key topics:
• Creating multi-cell packs
• Containing thermal runaway events

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
