  Battery Safety Analytics

  Despite their unrivaled performance and longevity, Lithium Ion batteries (LIBs) are also increasingly recognized as a safety hazard, especially in large scale energy storage installations. Although high-voltage battery packs and modules can be subject to numerous failure modes which are not present at the single cell scale, safety testing on full-scale battery packs can be prohibitively expensive and highly destructive to perform. In this talk, we demonstrate the importance of combining safety testing at the material, cell, and module scales to enhance the design of cells and packs which may mitigate the potential for catastrophe. Strategies to minimize full-scale testing requirements through a combination of carefully designed single cell tests and physics-based modeling are explored.

  This webinar will focus on the following key topics:

  • Bridging the gaps between safety concerns at single cell and module levels
  • Experimental characterization of li-ion cells under abusive conditions
  • Use of reference electrode instrumentation for degradation mode characterization
  • Selection of safe battery materials to enhance cell and module level safety
  • Role of modeling in ensuring safe battery design

  Thermal Runaway Testing and Cause Analysis of an Automotive Li-Ion Cell

  Part 1 focuses on the safety tests with large lithium-ion cells. We explain our test method and equipment to trigger and characterize a thermal runaway (TR). Then we present a case study with a large pouch cell which is brought into TR by over-temperature. We discuss the temperature curves, the voltage/resistance curves, gas releases and gas compositions.

  Part 2 covers composition analysis of large lithium-ion cells to interpret what happened during high temperature test. We also conduct thermal stability analysis of charged electrode to know the temperature when exothermic decomposition and oxygen release from cathode start. From that information, we can obtain key parameters to control thermal runaway from material design point of view.

  This webinar will focus on the following key topics:

  • Methods for safety tests of large lithium-ion cells
  • Thermal runaway of a large pouch cell caused by over-temperature
  • Detailed analysis of the gas, which is released during thermal runaway
  • Composition analysis of large scale lithium-ion cells
  • Thermal stability of charged electrode

  Introduction to Latest Analysis for PEMFC and Water Electrolysis

  A sustainable power device such as a PEMFC (Proton Exchange Membrane Fuel Cell) and water electrolysis have been developed for higher efficiency and better durability. A latest analytical technique and approach, critical to understanding the key factors of degradation mechanism and higher performance, will be discussed. TRC (Toray Research Center, inc.) has developed this approach to offer crucial information linked to these key factors.

  In this presentation, we will share this latest TRC technique along with some obtained results. For PEMFC, quantitative analysis using TEM tomography and distribution analysis of radical quencher within electrolyte, will be shown as the main new approach. Furthermore, 2 case studies will be introduced to show the effective analysis for water electrolysis devices.

  This webinar will focus on the following key topics:

  • Polymer electrolyte fuel cells
  • Water electrolysis
  • Analytical technique
  • Comprehensive analysis

  DER Tutorial Course 1/3: Energy Storage and DER Control Behind the Meter

  The implementation of distributed energy resources behind the meter has become increasingly commonplace for commercial, industrial, and even residential energy consumers. While energy security is often a key driver, it is demand charge management that provides the return on the infrastructure investment. DER aggregation and demand charge management technologies however, have not yet fully caught up with the relative maturity of the resources they control. Join John Chinnick, Principal Software Architect at Nuvation Energy for an examination of distributed energy resource management behind the meter, and how to integrate and manage DER assets for demand charge management.

  This webinar will focus on the following key topics:

  • Types and tiers of distributed energy resource management
  • Technical constraints and opportunities in asset management
  • Integrating energy resources for centralized control
  • A demand charge management implementation model
