The electric vehicle battery market is rapidly expanding, but the fire hazard associated with thermal runaway remains a critical issue. Thermal runaway occurs when a battery’s internal temperature rises uncontrollably, causing a fire or an explosion. This risk is heightened as battery energy density increases. To address this, numerous studies focusing on preventing thermal runaway are underway. Efforts include developing advanced thermal management systems, stabilizing electrolytes, and exploring new materials and designs that enhance battery stability. Improving manufacturing processes to reduce defects also plays a key role in minimizing the likelihood of thermal runaway. These research efforts are essential to ensure the safety and reliability of high-voltage batteries used in electric vehicles and other applications. This research proposes a method of inserting a thermal runaway device made of a polymer material into a high voltage battery case and damaging the polymer material according to the internal pressure change in the battery during thermal runaway. The pressure-dependent expansion compared to the size, shape, and physical properties of polymer materials was verified based on structural analysis and experimental data. The intention is to develop a device to prevent thermal runaway of high voltage batteries with polymer materials. The results of this study are expected to have a high technological ripple effect because it is possible to extinguish fires that may occur early in high-voltage batteries. Possible applications include construction, agricultural, and future transport devices using high-voltage batteries as well as electric vehicle batteries.
