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

Battery Ageing – How Modeling is Used to Predict Battery Life
Battery modeling and simulation makes it possible to analyze multiple operating conditions and design parameters for batteries and other electrochemical systems and processes. By developing mathematical models you can begin to understand the interaction of electrochemical and chemical processes in the battery and how these processes affect the performance and life of the battery.
In this presentation, we will take a look at the benefits of modeling and simulation in the design, selection, and operation of a lithium-ion battery. We will especially take a look at how modeling can be used together with testing. These results provide manufacturers and application experts with the data to not only predict battery life but to analyze the implications of design parameters and operating conditions to better understand the limitation of the battery.
This webinar will focus on the following key topics:
• Benefits of modeling and simulations in the design, selection, and operation of a lithium-ion battery
• Implications of design parameters and operating conditions with respect to experimental observations of battery performance, aging, and battery safety
• How battery modeling can be used together with testingPresenter

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
Christian Hanisch – CEO at Lion EngineeringChristian 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.

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
