Sulfide-based all-solid-state batteries are one of the most promising next generation energy storages. Especially the chlor-Argyrodite material Li6PS5Cl and ceramic sulfide Li7P3S11 are attractive solid electrolyte materials due to their high ionic conductivity. To date a lot of research in terms of material chemistry and cell design is presented in literature. From a production point of view, process parameter studies and process engineering are rarely addressed. To fabricate a thin-film sheet of the separator or composite cathode, conventional wet coating techniques from lithium-ion battery production can be applied, but processing has to be adapted to the properties of the sulfidic materials. Besides stable production atmospheres, the optimized processing is crucial to achieve the maximum possible energy density.
This webinar will focus on the following key topics:
• Changes in Manufacturing Processes from LIB to ASSB
• Requirements for Stable Production Atmospheres
• Choice of Process Parameters (Mixing, Coating, Drying)
• Correlation between cell energy density and optimizing manufacturing processes

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

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

Recycling of Lithium Ion Batteries From Electric Vehicles
The recycling of lithium-ion batteries – from EVs and others – will be discussed in this webinar.
Recently, the pilot plant of project LithoRec II could prove that a newly developed combination of process steps enables the recovery of a mass fraction of 75 % and more on a material recycling basis from lithium-ion batteries. This is supposed to be much better than state of the art. Combining different process steps like discharging, dismantling, shredding, sifting and air-jet separation the project partners were able to achieve their goal: proving that lithium-ion batteries can be recycled better. One interesting process dealing with the electrolyte came in a black box (which was actually white) and this was because of another ongoing patenting process of Lion Engineering. A modified and simplified process works to directly recycle scraps from the production of lithium-ion batteries – in order to protect both: the environment and the stakeholder’s money.
This webinar will focus on the following key topics:
• Recycling of Lithium Ion Batteries
• Recycling Yields and how to regain 75% and more – on a material recycling basis
• Direct Recycling of LIB-Production ScrapsPresenter

Electrochemical Impedance Spectroscopy and Its Application to Battery Analysis
Electrochemical Impedance Spectroscopy (EIS) is a well-established experimental technique that has applications in coatings, corrosion, sensors, electrochemical double layer capacitors, batteries among others. The power of EIS partly comes from its ability to access a very wide range of frequencies (typically from MHz to μHz). For batteries, parameters such as the internal resistance, electrode surface capacitance and leakage are accessible at different frequencies across the spectrum. This allows EIS to gather all the relevant information with a single measurement. In this webinar, we will briefly introduce EIS and cover its application to batteries. We will talk about how to analyze typical data and how to gather the relevant information. We will further talk about available instrumentation and their limitations.
This webinar will focus on the following key topics:
• What is impedance spectroscopy?
• What can impedance spectroscopy do for Battery analysis?
• How can capacitance, internal resistance and leakage be determined using EIS?
• What are the instrumental requirements and limits?Presenter
