How to evaluate energy storage performance of dielectrics?

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.

What are the characteristics of energy storage dielectrics?

For the energy storage dielectrics, the characteristics of high dielectric constant, low loss, large polarization difference (Δ P = Pmax - Pr), high breakdown strength, and good temperature stability are expected simultaneously to meet the application requirements.

What is the research status of different energy storage dielectrics?

What is the energy storage density of ceramic dielectrics?

First, the ultra-high dielectric constant of ceramic dielectrics and the improvement of the preparation process in recent years have led to their high breakdown strength, resulting in a very high energy storage density (40–90 J cm –3). The energy storage density of polymer-based multilayer dielectrics, on the other hand, is around 20 J cm –3.

Can a high-dielectric constant be used for dielectric energy storage?

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.

Does a low dielectric constant affect the energy storage property?

However, the low dielectric constant of polymer films limits the maximal discharge energy density, and the energy storage property may deteriorate under extreme conditions of high temperature and high electric field , , .
