    Enabling High-Rate Lithium Metal Anodes by Tailored Structures and Interfaces

    Oxide-based solid-state Li-batteries (SSLiBs) have the potential to be a transformational and intrinsically safe energy storage solution, due to their non-flammable ceramic electrolyte that enables the use of high-capacity Li metal anodes and high voltage cathodes for higher energy density over a much wider operating temperature range. However, their progress has been limited due to electrode/electrolyte interfacial issues. In particular, for Li-metal anodes concerns over dendrite formation/propagation and the requirement for elevated temperature and high stack pressure are still prevalent. To eliminate these concerns, a rational design of tailored structures and interfaces in Li-metal anodes will be presented. In addition, progress toward full cells using these tailored structures and interfaces will be presented.

    This webinar will focus on the following key topics:

    • Li-metal wetting of oxide electrolyte interface
    • Effect of oxide surface defects on Li dendrite formation
    • Effect of 3D structure on localized current density
    • Avoiding stack pressure to maintain uniform Li/oxide contact

    Detailed Approaches for Post-Mortem Analysis of Lithium Ion Batteries

    Performance degradation of Lithium Ion Batteries (LIBs) is an important problem not only battery users, but also for battery manufacturers and material suppliers. In this webinar, we will present two topics related to the Post-Mortem analysis of LIBs – one is the performance degradation of SiO anode, and the other is a detailed procedure for the quantitative analysis of electrolyte decomposition and SEI formation on graphite negative electrode.

    Toray Research Center can provide detailed and comprehensive data analysis of chemical and morphological changes, using latest instruments, to support material and product performance improvements. Customers can utilize the data set to investigate what may have happened inside the battery, and can correlate the performance degradation with that data analysis.

    This webinar will focus on the following key topics:

    • Lithium Ion battery
    • Post-Mortem analysis
    • SiO anode
    • Electrolyte degradation and SEI formation
    • Morphological observation and Composition analysis

    Advances in Battery Performance and Safety Testing using Calorimetry

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

    The first half of the presentation introduces isothermal calorimetry; focused on the new IBCx system from Thermal Hazard Technology (THT). Method of operation, hardware overview and examples of data will be presented.

    The second half of the presentation covers battery testing methods for the ARC adiabatic calorimeter system. The theoretical background of the test method will be described, and new developments to address blade-type batteries and high ampere-hour cells will be presented.

    The presentation also mentions complementary test methods and optional modules that can be integrated with calorimetry to provide more useful analysis. For example; fast-tracking heaters, online gas analysis etc.

    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
    • New product developments from THT to address market test requirements
    • Discussion of THT lab testing results
