    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 cells

    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

    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
