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

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 Scraps

Christian Hanisch – CEO at Lion Engineering
Christian studied Process Engineering at TU Braunschweig (Germany) and has worked in the research project LithoRec and designed LithoRec II at the Institute for Particle Technology / TU Braunschweig on the topic of Recycling of Lithium Ion Batteries. He developed and patented new recycling processes and led the project to the realization of a pilot plant. Recognizing the highest interest of industrial partners in this topic he co-founded the spin-off Lion Engineering GmbH with fellow PhD students and Professor Arno Kwade in 2011. Beginning in 2016, Christian started to focus full-time on being CEO of Lion Engineering.

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
