TUM: 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 processes

A PDF copy of the presentation will be sent to all attendees after the event.

(FREE) THT: Advanced Test Methods for Isothermal and Adiabatic Battery Calorimetry

This presentation describes two main types of calorimetric techniques that can be used to carry out performance and safety testing on lithium-ion and other high-energy batteries.

The first half of the presentation introduces isothermal calorimetry; the various types of instruments, the method of operation and examples of data which can be obtained, including new developments from THT.

The second half of the presentation covers battery testing methods for the ARC® adiabatic calorimeter system. The theoretical background of the test method is described and recommended practices for various types of testing are discussed.

The presentation also mentions complementary test methods that can be integrated with calorimetry to provide even more useful analysis, and new developments in test equipment from THT.

This webinar will focus on the following key topics:

• Principles of isothermal and adiabatic calorimetry testing for high-energy batteries
• Advantages and limitations of these two methods
• Discussion of different test types and results
• Recommended testing practices, limitations, future developments

A PDF copy of the presentation will be sent to all attendees after the event.

(FREE) TORAY: Comprehensive Analysis of Degraded PE Fuel Cells by Durability Tests

As a sustainable power source for automobiles, PEFC (Polymer Electrolyte Fuel Cells) have been investigated for further improvement of their durability. In general, the degradation of PEFCs is caused by various factors under operation. Thus, a comprehensive analysis is required to understand these important degradation factors.

This presentation will share evaluation by multi-analysis method of degraded PEFCs after their cycling. It was found that Si was contaminated in the cathode catalyst layer, and that Pt particles were enlarged in the cathode catalyst layer near the cathode gas outlet area. In addition, it was found that the degradation of the ionomer was more likely to occur near the cathode gas inlet area.

This webinar will focus on the following key topics:

• Polymer electrolyte fuel cells (PEFCs)
• Durability test
• Ionomer
• Comprehensive degradation analysis

A PDF copy of the presentation will be sent to all attendees after the event.
