    International Compliance for Small Portable Li Ion Batteries in 2021

    Does the Li Ion battery requirement for different countries confuse you? We will focus on the international requirements applied to small format portable Li Ion batteries. This will be an in-depth review of countries with mandatory requirements as well as voluntary or customer driven requirements. Every country has some very specific items that make them unique and these differences can lead to delays and potential changes in design if not understood ahead of time. We will review these gotcha items for each country we review. Finally, we will take a look at what is on the horizon for changes to standards and requirements globally.

    This webinar will focus on the following key topics:

    • Definition of scope – portable, small format Li ion batteries
    • Shipping regulations overview
    • Mandatory requirements
    • Voluntary or other requirements
    • Upcoming changes

    Characterizing Catalytic Inks for Fuel Cells

    Catalytic inks are key components when balancing cost, performance, and durability of proton exchange membrane fuel cells (PEMFC’s). Scaling up PEMFC production requires careful control of the ink to produce uniform electrode layers that use as little precious metal catalyst as possible. Particle size and dispersion critically impact the behavior of the ink and resulting performance of the electrode layers. X-ray diffraction, laser diffraction, dynamic light scattering, and X-ray fluorescence are characterization techniques with proven ability to scale-up in support of mass production that, when combined, provide a comprehensive overview of the particles in catalytic ink mixtures.

    This webinar will focus on the following key topics:

    • X-Ray Diffraction
    • Laser Diffraction
    • X-Ray Fluorescence
    • Dynamic Light Scattering

    These techniques each probe a different size regime and, when combined, provide a comprehensive overview of the particles in the catalytic ink mixture.

    BMS Tutorial Course 2/3: Battery Stack Design for UL 1973 Certification

    If you are developing a stationary energy storage system, chances are you have already heard of UL 1973 and UL 9540. Being certified to these important safety standards is quickly becoming the price of admission in the energy storage industry. When taking your battery stack design through the UL 1973 certification process, the level of effort is significantly impacted by the compliances and ratings of the individual components in your battery rack. Join Nate Wennyk, Senior Hardware Designer at Nuvation Energy, for an inside look at the development of UL 1973 Recognized battery stack solutions.

    This webinar will focus on the following key topics:

    • Understanding battery stack architecture
    • Impacts of component certifications on the UL 1973 LOE
    • Designing flexibility into a locked-down stack configuration
    • UL 1973 Recognition case studies and engineering war stories
