Film capacitors based on polymer dielectrics face substantial challenges in meeting the requirements of developing harsh environment (≥150 °C) applications. Polyimides have garnered attention as promising dielectric materials for high-temperature film capacitors due to their exceptional heat resistance.
Metallized film capacitors towards capacitive energy storage at elevated temperatures and electric field extremes call for high-temperature polymer dielectrics with high glass transition temperature (Tg), large bandgap (Eg), and concurrently excellent self-healing ability.
2.5. Prototypical metallized stacked polymer film capacitors for high-temperature applications To explore the applications of the high-performance Al-2 PI in electrostatic capacitors, we utilize Al-2 PI to construct prototypes of metallized stacked polymer film capacitors (m-MLPC) for applications at elevated temperatures.
Significantly, the charge–discharge test demonstrated a remarkably stable cyclability over 100,000 cycles at 150 °C under a high electric field of 400 MV/m, thereby highlighting the exceptional potential of the modified polyimides for high-temperature film capacitor applications.
