A New Generation of Aging Models for Lithium-ion Batteries
Over the past years, scientists have invested a lot of time and resources to optimize semi-empirical, physico-chemical, and data-driven simulation models. All of them show different challenges and limitations. To overcome this dead end, scientists and engineers combine physicochemical-mechanical degradation effects and integrate them into (semi)-empirical as well as data-driven approaches. We call this combination physics-motivated semi-empirical aging models.
This webinar will focus on the following key topics:
• How capacity aging model is optimized using bootstrap resampling
• The new generation of physics-motivated semi-empirical aging models: OCV aging, degradation modes, understanding the accuracy of models, simulation of swelling force
• The new TWAICE simulation model portfolio: base model, customized base model, premium model
• Vision and outlookPresenters

Failure Analysis of Next Generation Si Based Anodes
Silicon (Si) is an attractive alternative to graphite due to its high theoretical capacity of 3500 mAh-g-1 and its high abundance on earth. Unfortunately, Si is plagued by significant volume expansion during charge/discharge, upwards of 300%. As a result, researchers and companies have focused their attention on mitigating the disadvantages of Si. With various methods the aim is to create a Si based anode that has a stability comparable or better then graphite. With increasing interest, it is important to discuss and determine abuse testing and failure analysis techniques that can effectively determine the durability of these new anodes.
This webinar will focus on the following key topics:
• Why is it important to look at alternative anodes to graphite?
• The advantages and disadvantages of Si based anodes
• Creation of new anodes to alleviate the disadvantages of Si
• Customized abuse testing and failure analysis of Si based anode cellsPresenter

Challenges in Processing Large-Scale Sulfide-Based All-Solid-State Batteries
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 processesPresenter
