Webinar: Rework ability of gap fillers in EV battery packs

The fast-growing electric vehicle market demands robust and efficient thermal management solutions for battery packs, such as gap fillers and thermal pads. Gap fillers outperform thermal pads to achieve lower thermal impedance, as the gap fillers conform to surface roughness before curing. This allows gap fillers to adhere well to surfaces and provide mechanical support during normal operation. However, this also poses a challenge during repair, removal and re-manufacturing. Currently, there is no set standard for measuring vertical pull-off, and hence, there is a lack of knowledge on what level of pull-off force is needed to service these battery packs.

Tune in to this webinar presented by Anurodh Tripathi—Senior Scientist in the advanced chemical technology department at Parker LORD—to learn more about:

  1. How to test and measure vertical pull-off force
  2. Effects of factors such as surface properties (roughness, coating), material properties (silicone vs. urethane) and testing conditions (pull, rate, bond line thickness) on the vertical pull-off stress
  3. Data comparing performance of commercial liquid gap fillers and their ability to be reworked
  4. Recommendations on what battery designers should look for when selecting gap fillers

The webinar will be hosted by Charged on August 5, 2020, at 2:00pm EDT, and will include a presentation and a live Q&A session.
