    Electrolyte Flow Control to Reduce Dendrite and SEI Growth in Lithium Metal Batteries

    Dendrite growth in lithium metal batteries often leads to accelerated failure. SEI growth, breakage under excessive stress around dendrite tips, and re-growth on freshly exposed Li-surfaces leads to rapid capacity deterioration. Till date, a tough, mechanically stable SEI has been thought of as a necessity to prevent further SEI growth and to suppress dendrites. In this presentation, we will demonstrate that electrolyte flow can possibly eliminate dendrite growth, and also reduce SEI growth significantly, thus increasing stability and coulombic efficiency. The required electrolyte flow rates are low enough to be practically achieved by microfluidic pumping techniques.

    This webinar will focus on the following key topics:

    • Creeping normal electrolyte flow can eliminate dendrite growth
    • Creeping normal electrolyte flow increases the columbic efficiency and reduces SEI growth
    • Creeping parallel electrolyte flow significantly reduces dendrite growth
    • A mechanically stable tough SEI layer is not a necessity for stable dendrite free electroplating
    • Required flow rates may be achieved practically

    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

    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
