The demand for high-temperature dielectric materials arises from numerous emerging applications such as electric vehicles, wind generators, solar converters, aerospace power conditioning, and downhole oil and gas explorations, in which the power systems and electronic devices have to operate at elevated temperatures.
In addition, there is a positive correlation between the polarization and the relative permittivity (εr), the dielectric materials withstand the upper limit of the exerted electric field, which is called breakdown strength (Eb). Accordingly, the dielectric energy storage materials that possess concurrent high εr and Eb are desired for high Ue.
The strategy effectively suppresses electron multiplication effects, enhancing the thermal conductivity and mechanical modulus of dielectric polymers, and thus improving electric energy storage capacity. Briefly, the key problem of polymer dielectric energy storage materials is to enhance their dielectric permittivity.
Although the improvement of dielectric energy storage performance, it has paid a price in terms of processability, cost and energy loss. Noticeable gaps, on the other hand, remain between adoptions in academia (basic research) and industry (large-scale applications).
Blindly pursuing high-dielectric constant does not conform to the current trend in the development of dielectric energy storage. The use of high-electron-affinity organic semiconductive fillers can capture injected and excited electrons by strong electrostatic interaction, simultaneously suppressing leakage current and improving breakdown strength.
The accumulated energy in the capacitor during several charging cycles can be quickly released to generate a strong pulse power. Besides U, Urec, and η, the temperature stability, fatigue endurance, and discharge time are also important parameters for evaluating the energy storage performance of the dielectrics.
From the point of view of material properties, inorganic/organic dielectric materials, on the other hand, also have excellent energy storage performance. Unfortunately, it is hard to apply this strategy into the film capacitor industries in a short time owing to the poor processability and flexibility.
The demand for high-temperature dielectric materials arises from numerous emerging applications such as electric vehicles, wind generators, solar converters, aerospace power conditioning, and downhole oil and gas explorations, in which the power systems and electronic devices have to operate at elevated temperatures.
