Are dielectric film capacitors suitable for high-temperature energy storage applications?

Dielectric film capacitors for high-temperature energy storage applications have shown great potential in modern electronic and electrical systems, such as aircraft, automotive, oil exploration industry, and so on, in which polymers are the preferred materials for dielectric capacitors.

Can dielectric materials withstand high-temperature capacitors?

Various classes of dielectric materials have been developed for high-temperature capacitors, but each has its own limitations. Normally, ceramics can withstand high temperature and exhibit high ɛr, but low breakdown strength (E b) and large variation of dielectric properties versus temperature limit their applications.

Can electrostatic capacitors be used in high-temperature electric power systems?

This work shows the fabrication of capacitors with potential applications in high-temperature electric power systems and provides a strategy for designing advanced electrostatic capacitors through a metadielectric strategy.

What are the limiting factors for high-temperature capacitors?

However, low E b of ceramics and low ɛ r of glass, unstable temperature-dependent permittivity, the increasing hysteresis and conduction loss are limiting factors for high-temperature capacitors. A variety of inorganic bulk and thin films dielectrics have been exploited for high-temperature applications.

Can MDS be used for high-temperature energy storage capacitors?

The integration of high thermal conductivity and low dielectric loss is a benefit for high-temperature energy storage capacitors. The MDs are an emerging new composite material designed and manufactured artificially with unexpected properties 30, 31. Till now, however, MDs for high-temperature energy storage applications are still unexplored.
