Lithium-sulfur batteries can displace lithium-ion by delivering higher specific energy at a lower cost. Presently, however, the superior energy performance fades rapidly due to instability issues of the electrodes and the electrolyte. Extensive research and considerable progress over the past ten years have solved the instability issue of the sulfur electrode to a large extent. However, the formidable challenges of the more difficult electrode, lithium metal, (safety and cyclability) are yet to be resolved. Therefore, Lithium-Sulfur battery research programs should have at their heart, stabilizing the lithium electrode, as addressing it is predicted to ensure a rapid transition to commercial level life-spans. After all, the highest specific energy can be achieved by battery chemistries that utilize lithium metal as the negative electrode.
This webinar will focus on the following key topics:
• What’s so good about sulfur?
• Great capacity brings great stress!
• Will we see the revolutionary return of Lithium metal?
• Electrolyte challenges (we need too much of it but it’s heavy!)
• Current status and future prospects

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 limitsPresenter

Lithium Ion Capacitors – Combining Energy with Power
FREE Webinar – JSR Micro, Inc. is a proud sponsor of this event.
Lithium Ion Capacitors (LIC) are hybrids of electric double-layer capacitors (EDLCs) and lithium ion batteries (LIB). Combining the reversible non-Faradaic cathode from an EDLC and the reversible Faradaic anode from an LIB results in an ultra or super capacitor with significantly increased energy density, improved float performance and low self-discharge rates. Avoiding the lithium metal oxide cathodes from LIB’s improves the inherent safety and eliminates Cobalt content, however still combines aspects of energy & power of both cell types. The Faradaic intercalation/deintercalation reactions at the anode are capable of generating a significant amount of charge, while the non-Faradaic electrostatic storage of the electrical energy formed at the interface of the electrode and the electrolyte, known as an electric double layer, results in fast charge and discharge capabilities for hundreds of thousands, if not millions of cycles.
This webinar will focus on the following key topics:
• What is an LIC? Technology Introduction
• Key Benefits
• Safety
• EDLC vs LIC
• ApplicationsPresenter

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

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

– 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
