Pressure-Sensitive Adhesive Tapes for Use with Mica in EV Batteries

EV battery engineers are increasingly turning to mica as a material solution to improve vehicle reliability and safety by containing thermal runaway. Pressure-sensitive adhesive tapes are now a preferred solution for bonding mica materials in a battery pack. This paper explores a common challenge associated with using PSA tapes with mica. Referencing laboratory data, it provides guidance for those involved in design and assembly.
