    Battery Management System Impacts on Energy Storage

    Battery management systems impact the utility, effectiveness, and life of an energy storage system. Passive balancing is less expensive than active balancing, but weaker cells or modules may need to be replaced near the end of the ESS’s lifespan. Active balancing transfers energy from stronger to weaker cells, but at a higher system cost and design complexity.

    System down time is associated with both approaches and carries such a high opportunity cost that innovations in this area may be of greater importance than the type of balancing being employed.

    Join Nuvation Energy CEO Michael Worry for an exploration of the current state of the art in battery cell balancing, and how BMS innovations will impact the future of stationary energy storage.

    This webinar will focus on the following key topics:

    • A stationary ESS orientation on battery management
    • Understanding balancing-related down time
    • Comparing active and passive balancing
    • Innovations in battery management

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

    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

    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
