  • SERMA: Combining Characterization Techniques for Supporting Development of Batteries

    Wednesday, August 31, 2022 | 10:00 A.M. EDT USA

    The complexity and scale of different physical-chemical processes inside batteries render any development to be strongly dependent on their proper description and monitoring, from nano-scale to the system-scale. Using different case studies solved by the TEESMAT platform, we will demonstrate how the combination of standard and advanced characterization techniques can support the development of new batteries. Among some examples, we will present:

    – Probing the failure mechanisms of new ultra-capacitors
    – Analyzing commercial Li-ion cells for envisaging a second life (safety)
    – Understanding the copper oxidation phenomena during the fabrication process
    – Quality control of electrodes
    – Fine characterization of polymer based electrolyte for future Li-ion batteries

    This webinar will focus on the following key topics:

    • Complexity of electrochemical energy storage systems
    • Efficient characterization tools – from nano-scale to pack size
    • Case studies on full value chain – material level, electrochemical mechanisms, production processes, safety, and increased device performance

    A PDF copy of the presentation will be sent to all attendees after the event.

    Cyril Marino, PhD – Project Leader at Serma Technologies

    Dr. Cyril Marino obtained a PhD on material science about the understanding of electrochemical phenomena for the conversion materials used as negative electrode for Li-ion batteries at Université Montpellier 2 (France) in 2012. He was pursuing in the field of research with one assistant professor position at Technische Universität München (Germany) and one scientist position at Paul Scherrer Institut to work on the understanding of high voltage cathode materials for Li-ion batteries and the development of Na-ion batteries. He joined Serma Technologies in March 2019 as electrochemical energy storage systems Expert and is the TEESMAT project leader at Serma.

  • PURDUE UNIVERSITY: Electrode Damage Characterization in Li-Ion Batteries Using Raman Spectroscopy

    Wednesday, September 21, 2022 | 10:00 A.M. EDT USA

    While Li-Ion battery technology has continually advanced to provide cells that are smaller and more powerful, compromised safety concerns due to physical damage are always present. Physical damage to a Li-Ion battery can significantly affect its operational performance, causing accelerated degradation and capacity fade. Damage to electrodes and removal of active material lead to microstructural changes in electrode material and unbalanced current distribution, causing polarization in cells. This work focuses on characterizing the effects of partial nail penetrations on electrodes in cells that continue cycling after being damaged by using Raman spectroscopy and incremental capacity analysis. This helps to determine the type and extent of damage to the electrodes over the course of their abbreviated lifetime.

    This webinar will focus on the following key topics:

    • Dynamic impact testing of prismatic Li-Ion cells
    • Raman spectroscopy analysis for anode damage characterization
    • Increased polarization due to unbalanced current distribution
    • Accelerated degradation caused by physical damage
    • Incremental capacity analysis to determine mechanisms of aging

    A PDF copy of the presentation will be sent to all attendees after the event.

  • TUM: Challenges in Processing Large-Scale Sulfide-Based All-Solid-State Batteries

    Wednesday, November 02, 2022 | 10:00 A.M. EDT USA

    Sulfide-based all-solid-state batteries are one of the most promising next generation energy storages. Especially the chlor-Argyrodite material Li6PS5Cl and ceramic sulfide Li7P3S11 are attractive solid electrolyte materials due to their high ionic conductivity. To date a lot of research in terms of material chemistry and cell design is presented in literature. From a production point of view, process parameter studies and process engineering are rarely addressed. To fabricate a thin-film sheet of the separator or composite cathode, conventional wet coating techniques from lithium-ion battery production can be applied, but processing has to be adapted to the properties of the sulfidic materials. Besides stable production atmospheres, the optimized processing is crucial to achieve the maximum possible energy density.

    This webinar will focus on the following key topics:

    • Changes in Manufacturing Processes from LIB to ASSB
    • Requirements for Stable Production Atmospheres
    • Choice of Process Parameters (Mixing, Coating, Drying)
    • Correlation between cell energy density and optimizing manufacturing processes

    A PDF copy of the presentation will be sent to all attendees after the event.
