    EIS for Energy Storage Tutorial Course 2/3 – How to Perform Good and Reliable EIS Measurements

    Electrochemical Impedance Spectroscopy (EIS) is a powerful technique, but it might be difficult to know which parameters to set as it really depends on the studied system. We give a few guidelines and tools needed to set the right amplitude, as well as other experimental parameters of interest that can increase the accuracy and the reliability of your measurement.

    A discussion will be given about when and whether to choose between potentio-controlled or galvano-controlled EIS.

    Finally, we will give recommendations on the conditions that the system under study should fulfill, especially time-variance, with some examples on the effect it has on impedance data and how to correct them.

    This webinar will focus on the following key topics:

    All Solid-State Batteries and the Future of Energy Storage

    The development of all solid-state batteries (ASSBs) has seen tremendous progress in recent years. However, several barriers still need to be overcome before ASSBs can be commercialized. These obstacles include poor interfacial stability, scalability challenges as well as the difficulty to precisely diagnose problems within the cell. Additionally, efforts to develop sustainable recyclability in lithium ion batteries are still lacking. In this webinar, we discuss SSEs chemistries and its implications on interfacial stability. We also cover the current state-of-the-art characterization techniques and evaluate future ASSB prototyping strategies. Finally, we hope to discuss potential strategies toward a sustainable ASSB recycling model to address the growing lithium ion battery waste problem.

    This webinar will focus on the following key topics:

    • Overview of solid-state batteries and solid-state electrolyte research
    • Importance of interfacial stability – correlate chemical, electrochemical and mechanical-induced reactions
    • Challenges for diagnosis / characterization of buried interfaces and lithium dendrites
    • Scalable fabrication considerations of commercialized all-solid-state batteries
    • Sustainability – Battery recycling concerns of Cost, Efficiency and the Environment

    Will Lithium-Sulfur Batteries be Part of the Future of Energy Storage?

    Lithium-sulfur batteries can displace lithium-ion by delivering higher specific energy at a lower cost. Presently, however, the superior energy performance fades rapidly due to instability issues of the electrodes and the electrolyte. Extensive research and considerable progress over the past ten years have solved the instability issue of the sulfur electrode to a large extent. However, the formidable challenges of the more difficult electrode, lithium metal, (safety and cyclability) are yet to be resolved. Therefore, Lithium-Sulfur battery research programs should have at their heart, stabilizing the lithium electrode, as addressing it is predicted to ensure a rapid transition to commercial level life-spans. After all, the highest specific energy can be achieved by battery chemistries that utilize lithium metal as the negative electrode.

    This webinar will focus on the following key topics:

    • What’s so good about sulfur?
    • Great capacity brings great stress!
    • Will we see the revolutionary return of Lithium metal?
    • Electrolyte challenges (we need too much of it but it’s heavy!)
    • Current status and future prospects

    Experimental Investigation of Cascading Failure in Lithium Ion Cell Arrays – Impact of Cathode Chemistry

    In lithium ion arrays, thermal runaway may propagate from a failing cell to neighboring cells and grow into a large-scale fire in a phenomenon referred to as cascading failure. A new experimental setup was developed to investigate cascading failure using 12 cell arrays constructed from cells of 18650 form factor. Thermal runaway was initiated in one cell using an electric heater and observed to propagate through the array using temperature sensors. Cascading failure was studied in nitrogen or air environment to elucidate the impact of combustion. The cell temperature allowed calculation of row-to-row propagation speed in arrays of different cathode chemistries. The yields of oxygen, carbon monoxide, carbon dioxide, total hydrocarbons and hydrogen were measured; corresponding fire hazards were assessed.

    This webinar will focus on the following key topics:

    • Thermal runaway propagation
    • Thermal runaway hazards
    • Failure dynamics
    • Flammability and toxicity
    • Failure Mitigation and suppression
