The research status of different energy storage dielectrics is summarized, the methods to improve the energy storage density of dielectric materials are analyzed and the development trend is prospected. It is expected to provide a certain reference for the research and development of energy storage capacitors.
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.
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.
This article presents an overview of recent progress in the field of nanostructured dielectric materials targeted for high-temperature capacitive energy storage applications. Polymers, polymer nanocomposites, and bulk ceramics and thin films are the focus of the materials reviewed.
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 , , .
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.
