Film capacitors have shown great potential in high-power energy storage devices due to their high breakdown strength and low dielectric loss. However, the state-of-the-art commercial capacitor dielectric, biaxially oriented polypropylene (BOPP), exhibits limited energy storage density below 2 J cm −3 because of its low dielectric constant
As an important power storage device, the demand for capacitors for high-temperature applications has gradually increased in recent years.
