  Preventing Li Ion Battery Failures From a Manufacturing and Design Perspective

  How can you be proactive and make sure your cell supplier is the right one and you don’t end up with thermal events and field failures? Is it enough to qualify a cell manufacturer according to industry standards? The answer is that the majority of compliance based testing is related to abuse tolerance. However, the vast majority of field failures do not occur under abuse scenarios, but happen under normal operating conditions due to manufacturing flaws or design and system tolerance issues that cause internal shorts. In this webinar, you will learn about common lithium ion battery failure modes and how to be proactive in preventing these.

  This webinar will focus on the following key topics:

  • Gain an understanding of lithium ion battery failure mechanisms and the pathway to thermal events
  • Learn how cell design impacts battery safety and reliability
  • Learn the basic steps in a lithium ion cell manufacturing process, and how the process controls affect safety and reliability
  • Come away with a checklist to qualify your cell manufacturer

  Addressing Engineering Challenges of Vehicle Electrification With Model-Based Systems Engineering

  The concern for the environment and energy savings is changing the way we think about transportation. Wide spreading vehicle electrification – not only through Electric Vehicles (EV) and Hybrid Electric Vehicles (HEV), but also electrification in conventional vehicles – has become a common trend of the industry and the upcoming battlefield to install new leading positions. Accounting for costs, reliability, safety, performance, customer acceptance, infrastructure and design process makes manufacturers and suppliers facing new engineering challenges that need to be addressed in a very short time-frame.

  Technologies used for electrification are causing a growing complexity in systems and components, and producing vehicles designed right, first, at reasonable costs make the implementation of collaborative mechatronic system simulation a decisive and mandatory step in the engineering process.

  This webinar will focus on the following key topics:

  • What are the global trends and challenges of vehicle electrification?
  • What are the available technologies for reducing CO2 emissions?
  • What are the benefits of stop & start and regenerative braking systems?
  • How to characterize battery and optimize its thermal management?
  • How do energy storage architectures impact battery aging?

  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

  Recycling of Lithium Ion Batteries From Electric Vehicles

  The recycling of lithium-ion batteries – from EVs and others – will be discussed in this webinar.

  Recently, the pilot plant of project LithoRec II could prove that a newly developed combination of process steps enables the recovery of a mass fraction of 75 % and more on a material recycling basis from lithium-ion batteries. This is supposed to be much better than state of the art. Combining different process steps like discharging, dismantling, shredding, sifting and air-jet separation the project partners were able to achieve their goal: proving that lithium-ion batteries can be recycled better. One interesting process dealing with the electrolyte came in a black box (which was actually white) and this was because of another ongoing patenting process of Lion Engineering. A modified and simplified process works to directly recycle scraps from the production of lithium-ion batteries – in order to protect both: the environment and the stakeholder’s money.

  This webinar will focus on the following key topics:

  • Recycling of Lithium Ion Batteries
  • Recycling Yields and how to regain 75% and more – on a material recycling basis
  • Direct Recycling of LIB-Production Scraps
