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.
What You’ll Learn:
How to test and measure vertical pull-off force
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
Data comparing performance of commercial liquid gap fillers and their ability to be reworked
Recommendations on what battery designers should look for when selecting gap fillers
Jon Fold von Bülow recieved his Cand. Scient. in Nanoscience from University of Copenhagen in 2011 and is currently working with upscaling Li- and Na-ion battery materials to the 100+ kg scale for Haldor Topsøe A/S.
Jon's main interest lies in energy technologies for the future and he started working with fusion energy at Risø National Laboratory for Sustainable Energy. He has since developed a growing interest in technologies that are closer to potential industrial application. He is a highly dedicated academic as well as a very active professional and have initiated and participated in many different projects.
His studies within nanotechnological material science and affiliation with Risø National Laboratories has taken him to Germany, China and the US, where he has collaborated independently with several international research groups. He has so far succeeded in pushing two academic projects to industrial application, first with the Danish company Coloplast A/S and recently with a California-based battery start-up – an invention that is currently being US patented.
Jon has conducted most of his work on Li-batteries in the facilities of California NanoSystems Institute (CNSI) as a research scholar at UCSB-MIT-Caltech Institute for Collaborative Biotechnologies (ICB). The manganese based cathode materials he fabricated during this period were all tuned for high-power applications and covers synthesis of various manganese oxides from solution, molten and solid states.
