Choosing a dielectric protection barrier during the design and construction of EV battery modules and packs is a critical engineering decision. With an optimized solution, engineers can maximize pack energy density, improve vehicle reliability, and enhance consumer safety.

In this session, Max VanRapporst and Scott Kruskinski of Avery Dennison Performance Tapes will discuss the comparative advantages of using pressure-sensitive adhesive tapes versus coatings to create dielectric barriers. He’ll explain how to choose a specific dielectric tape based on the application, including pack electrical insulation, cell wrapping, cooling plates, and insulation around flexible busbars. He’ll also discuss how proper tape selection can help maximize scale-up and large-volume production. Finally, Max will highlight some of the potential pitfalls and failure modes that can occur when the wrong dielectric protection barriers are chosen.
