  Battery Selection Tutorial Course 2/3: Beyond the Standards: Device-Specific Testing

  After choosing your cell and manufacturer (Part 1 of this series), most likely, they will have passed the tests of various standards organizations. However, depending on your operating environment, you may need to go above and beyond the baseline to ensure your product operates as intended. This webinar is Part 2 in a three-part series and will review a variety of factors to consider in your device-specific testing, including designing tests to predict the outcomes of various user-abuse scenarios, understanding the mechanisms of gas generation, capacity retention based on different voltage windows, and what happens if you need to cycle your cells outside of their operating range (outside in an Arizona summer or Minnesota winter, for example).

  This webinar will focus on the following key topics:

  • User-abuse scenarios to prevent against
  • Causes and effects of various gas generation mechanisms
  • Voltage limits

  Solid Electrolytes and Bulk Scale Solid-State Batteries

  Recently, the push to move beyond Li – ion battery technology has grown. Several advanced battery technologies & chemistries have been identified as promising candidates including i) solid-state batteries with Li metal anode, ii) Li – S chemistries, iii) Li – air(oxygen), and iv) flow batteries. Although an engineered solution using liquids may be possible for some of these options, a solid electrolyte is an enabling technology for each of these beyond Li – ion alternatives. This webinar will introduce the operating principles of each of these cell technologies and solid electrolytes will be discussed in this context. The requirements of a solid electrolyte will be outlined & several state of the art solid electrolytes will be compared. Recent technical progress towards the fabrication of solid-state batteries will be reviewed. Finally, an overview of market applications for solid-state will be presented.

  This webinar will focus on the following key topics:

  • Overview of beyond Li – ion battery technologies enabled by solid electrolytes
  • Comparison of state of the art solid electrolytes
  • Recent technical progress towards solid-state batteries
  • Review of market applications for solid-state batteries

  Electric Vehicle and Hybrid Sales and Market Prospects Through 2020 – It’s Not What “They” Say

  Some industry observers have proclaimed that the electric vehicle market in the U.S. is failing. While overall sales have declined somewhat in recent months, this view is simplistic and short-sighted. A number of key products are at the end of their life cycle, with new versions on the way, and a variety of all-new products are coming. Strength in trucks and crossovers currently works against sales of these vehicles, but that will also change going forward.

  The increase in product offerings is led by a number of factors including consumer interest, regulatory requirements and government incentives in the U.S. and elsewhere, technology and cost improvements, and an interest by various automakers in making a corporate statement.

  The role of dealers has been a problem that has received little attention. There are methods to address this issue, but they are often not utilized.

  This webinar will focus on the following key topics:

  • Current Issues Affecting Sales
  • Product Actions and Sales Forecast by Vehicle Type – Micro Hybrids, Mild Hybrids, Regular Hybrids, Plug In Hybrids, Battery Electrics, and Fuel Cells
  • Key Trends by Vehicle Type – Now & Going Forward
  • Importance of Regulatory Policy Including California Zero Emission Vehicle Rules and EPA/NHTSA Midterm Review
  • Various Automakers Have Very Different Strategies to Electrification

  Avoid Battery Explosions and Fires – With Right Data and Better Designs

  Modern Li Ion batteries contain hazardous chemicals and heat up during use – this combination always has the potential to cause fires and explosions. This presentation will focus on improving the understanding of how such incidents occur, what can be done to avoid them and how the risk can be minimized during early stage design.

  The solution lies in knowledge of the heat generation rate during normal use, and information about safe boundaries such as temperature, discharge rate & overcharge in realistic situations that represent actual conditions of use. Data from commercial batteries of different types, including videos of batteries undergoing thermal runaway, will be used to illustrate these points.

  A relatively new technique will also be discussed with data, which allows total heat output during discharge to be measured on-line and this can be used both for design and battery modelling. Examples of the data will be provided.

  This webinar will focus on the following key topics:

  • Why battery fires and explosions occur
  • How to design safer batteries through understanding of heat generation
  • Video evidence of batteries under explosive conditions
  • How better thermal management systems can be designed – based on heat measurement from isothermal calorimetry
  • Laboratory instruments suitable for testing and data generation
