The energy storage density of the metadielectric film capacitors can achieve to 85 joules per cubic centimeter with energy efficiency exceeding 81% in the temperature range from 25 °C to 400 °C.
The electrification of transport and growing demand for advanced electronics require polymer dielectrics capable of operating efficiently at high temperatures. In this review, we critically analyze the most recent development in the dielectric polymers for high-temperature capacitive energy storage applications.
Since the stored energy density is proportional to the dielectric constant, the energy density of the capacitors can be increased by increasing the dielectric constant, which would reduce the volume and weight of the capacitors to meet the ever-increasing demand on highly integrated, compact, and miniaturized electronics and electric power systems.
