This study aims to evaluate the applicability of composite pouch films containing ionite as heat-suppressing pouch films for secondary batteries by manufacturing them and assessing their structural characteristics and temperature changes during charging and discharging. Film coating was performed using Coretech CT-AF300 to produce pouch films with varying ionite content and particle size. The influence of plasma treatment on the surface condition of PET film, aimed at improving coating adhesion, was also examined to derive optimal manufacturing conditions. Furthermore, the temperature characteristics of the pouch film during charging and discharging were investigated using an infrared thermal imaging camera and a self-developed test apparatus, respectively, to assess the feasibility of developing next-generation high-performance pouch films.
