  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

  Enterprise Battery Intelligence for Mobility Electrification

  Electrification is the largest disruption to the transportation industry in its 125-year history – Enterprise Battery Intelligence software is key to the future of EV companies.

  With over 160,000 EV battery-related recalls in Q4 2020 alone, EV companies are investing billions of dollars in the facilities, teams and infrastructure needed to gain a deeper understanding of their batteries and how batteries impact their business. Developing, manufacturing and operating high-quality battery-powered products requires a deep understanding of battery behavior in real-world application settings. To do this well, EV companies must marshal mountains of data spanning the test lab, production line and vehicles operating in the field.

  This webinar will focus on the following key topics:

  • Enterprise Battery Intelligence software is key to your company’s future
  • Batteries can add tremendous value—or incur serious costs
  • A deep and holistic understanding of batteries is required to innovate, qualify new batteries and materials, ensure on-time product launches, reduce risk, determine resale/second-life value, increase ROI, among other business critical issues

  Battery Performance and Testing – Why Pursue Failure Analysis

  Your product is only as good as the battery! Unfortunately, battery product failures can happen at any time.  What should you do when you experience a battery failure?  Why even bother with battery failure analysis? What can it teach you about selecting the correct battery solution – and battery supplier – for your products? Should your battery supplier or a 3rd party be used to conduct the investigation?  One of the compelling reasons for a detailed failure analysis is it results in better yields, profitability, and better business.  Failure analysis leads to knowledge, which leads to improvement that strengthens the performance of a company’s product and its brand. Russ Gyenes, principal engineer at Energy Assurance will answer these questions from his years of experience investigating and being a legal expert on Lithium-Ion failure analysis.

  This webinar will focus on the following key topics:

  • Why pursue failure analysis
  • Why ask an outsider for help
  • Third-part lab value and expertise
  • What you can do to help
  • What you should expect
  • What you should not expect
  • Typical steps

  Calorimetric Measurements of Lithium-Ion Batteries Under Use and Abuse

  This presentation will describe two main types of calorimetric techniques that can be used to carry out performance and safety testing on batteries. These are isothermal calorimetry and adiabatic calorimetry.

  The first half of the presentation will introduce isothermal calorimetry; the various types of instruments, the method of operation, and examples of data that can be obtained. The second half of the presentation will cover battery testing methods for the ARC adiabatic calorimeter system. The theoretical background of the test method will be described, and recommended practice for various types of testing will be discussed.

  The presentation will also mention complementary test methods that can be integrated with calorimetry to provide even more useful analysis.

  This webinar will focus on the following key topics:

  • Principles of isothermal and adiabatic calorimetry for batteries
  • Advantages and limitations of these two methods
  • Discussion of applications and results
  • Recommended testing practices
