Dielectric Coatings for Battery Packs

Dielectric Coating for Battery Packs

Sipiol UV is a UV-cured, VOC-Free, 100% solids, dielectric coating that cures in seconds that has superior adhesion to metals and plastics. Sipiol UV coatings was specifically formulated for edge coverage and flexibility to prevent catastrophic battery fires. The strong adhesion and flexibility blends itself to many applications in the battery assembly.

Webinar Dielectric Coating for EV Battery Packs

Sipiol UV can replace PET on Cylindrical and Prismatic Cells which will eliminate delamination at corners and seams and has superior adhesion to battery cells. Sipiol UV will not de-bond or delaminate during use. Our dielectric paint contains unique properties with good coverage and high flexibility, allowing it to be applied to complex geometries where other battery coatings or tapes may fail. Production time can be reduced with the rapid cure time in a matter of seconds, not hours. Note: the delamination with the sharp corner and maintaining isolation is vital to safety in high voltage batteries and even more important as density energy increases.

Watch as Parker collaborates closely with a leading battery manufacturer to address a critical issue: the delamination caused by traditional PE tape at the edges of batteries.

Our chemistry can cure rapidly when exposed to the appropriate wavelength and the intensity of light. When UV light is applied to the liquid coating, the photoinitiator produces free radicals which begin the chain reaction when polymerizing the liquid monomers into a cross linked and cured coating.

Assessing Technologies for Dielectric Protection of Battery System Components

With the growth and development of battery pack technologies, manufacturers of electric vehicles (EV) place greater emphasis on pack design optimization, seeking more compact solutions to improve energy density and reduce cost. Dielectric protection is critical in the assembly of high-voltage battery packs. Manufacturers often apply dielectric materials to the battery cells, cooling plates and adjacent components.

Several types of dielectric materials exist on the market today. Four of them will be discussed, tested, and compared in this paper.
