Augment Your Battery Research With Non-Ambient In Operando XRD
Recently, in operando research on batteries with XRD system in room temperature has provided great understanding on the dynamic migration of the electrode materials during the charge cycle. However, a battery may work perfectly at ambient temperature, but actual environment may cause unexpected performance degradation and safety risks. To investigate battery stability under non-ambient conditions, we are introducing 2 variable temperature electrochemical cell (VTEC) battery stages with heating and cooling feature between -10°C and 70°C on the Empyrean XRD platform. In combination with comprehensive instruments control software and powerful data visualization and analysis tools made for large XRD datasets in HighScore Plus, we provide the most advanced in operando in situ solutions to accelerate your battery research.
This webinar will focus on the following key topics:
• Advanced non-ambient in operando studies on batteries with Empyrean XRD system
• Synergy amongst potentiostat, Empyrean and temperature controller
• Fully automated data analysis with HighScore Plus
o electrode phase identification and quantification
o crystal structure and defects analysis
o cluster analysis
o intuitive and powerful visualization tools made for in-operando experimentsPresenter

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 analysisPresenter

High-Throughput Battery Materials Analysis for Gigafactories
The Gigafactory model requires reliable materials characterization to achieve the promised efficiencies of vertical integration. Unifying the synthesis of battery materials, processing such as dispersion into inks, and production of cells is the first step to high-volume production and reducing vulnerability to supply chain problems. These steps benefit from automated high-throughput materials analysis that can be used for process control. This webinar will discuss in-line and at-line instrumentation combined with automated analyses from microstructural (particle size with laser diffraction) to chemical (stoichiometry with XRF) to atomic level (Li/Ni site mixing with XRD).
This webinar will focus on the following key topics:
• In-line and at-line materials characterization and automated analyses
• Asset management to maximum uptime
• At-line X-ray diffraction analysis of lattice parameters and Li/Ni site mixing
• At-line X-ray fluorescence analysis to quantify Ni-Mn-Co stoichiometry
• In-line particle size analysis to control milling during dispersionPresenter

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 developmentsPresenter
