An electrostatic capacitor has been widely used in many fields (such as high pulsed power technology, new energy vehicles, etc.) due to its ultrahigh discharge power density. Remarkable progress has been made over the past 10 years by doping ferroelectric ceramics into polymers because the dielectric constant is positively correlated with the energy storage density. However, this method often leads to an increase in dielectric loss and a decrease in energy storage efficiency. Therefore, the way of using a multilayer structure to improve the energy storage density of the dielectric has attracted the attention of researchers. Although research on energy storage properties using multilayer dielectric is just beginning, it shows the excellent effect and huge potential. In this review, the main physical mechanisms of polarization, breakdown and energy storage in multilayer structure dielectric are introduced, the theoretical simulation and experimental results are systematically summarized, and the preparation methods and design ideas of multilayer structure dielectrics are mainly described. This article covers not only an overview of the state-of-the-art advances of multilayer structure energy storage dielectric but also the prospects that may open another window to tune the electrical performance of the electrostatic capacitor via designing a multilayer structure.

“…Deviations from the ideal are well known from testing of polymer composites and are termed percolation In order to meet the requirements for high dielectric constant, low losses, high voltage, multilayer systems in which the layers have every distinct and different properties and only one of the layers has a high dielectric constant. Reviews of multilayer, high energy density systems are given in [20][21][22]. The multilayer arrangement combines one or two layers having a high dielectric constant with or two layers with very high resistance, high breakdown strength, and relatively low dielectric constant.…”

In this paper, the design of high energy density dielectric capacitors for energy storage in vehicle, industrial, and electric utility applications have been considered in detail. The performance of these devices depends primarily on the dielectric constant and breakdown strength characteristics of the dielectric material used. A review of the literature on composite polymer materials to assess their present dielectric constants and the various approaches being pursued to increase energy density found that there are many papers in which materials having dielectric constants of 20–50 were reported, but only a few showing materials with very high dielectric constants of 500 and greater. The very high dielectric constants were usually achieved with nanoscale metallic or carbon particles embedded in a host polymer and the maximum dielectric constant occurred near the percolation threshold particle loading. In this study, an analytical method to calculate the dielectric constant of composite dielectric polymers with various types of nanoparticles embedded is presented. The method was applied using an Excel spreadsheet to calculate the characteristics of spiral wound battery cells using various composite polymers with embedded particles. The calculated energy densities were strong functions of the size of the particles and thickness of the dielectric layer in the cell. For a 1000 V cell, an energy density of 100–200 Wh/kg was calculated for 3–5 nm particles and 3–5 µ thick dielectric layers. The results of this study indicate that dielectric materials with an effective dielectric constant of 500–1000 are needed to develop dielectric capacitor cells with battery-like energy density. The breakdown strength would be 300–400 V/µ in a reverse sandwich multilayer dielectric arrangement. The leakage current of the cell would be determined from appropriate DC testing. These high energy density dielectric capacitors are very different from electrochemical capacitors that utilize conducting polymers and liquid electrolytes and are constructed much like batteries. The dielectric capacitors have a very high cell voltage and are constructed like conventional ceramic capacitors.

“…Previous reports indicate that the interfaces between the two different dielectric layers (partially) block charge carrier movement, which can effectively limit the development of electrical breakdown trees in the multilayer films and consequently enhance the breakdown strength and energy-storage density. [3,[27][28][29][30][31][32] Modeling suggested that the increase of the breakdown strength in multilayer structures may be attributed to the effect of the electric-field distribution, the inhibition of local electric-field distortions, interface resistance, and the interface blocking effect. [29,31,33] Several studies show that an enhanced breakdown strength is achieved with increasing period number.…”

Multilayer thin‐film dielectric capacitors with high energy‐storage performance and fast charge/discharge speed have significantly affected the development of miniaturized pulsed‐power devices. Here, the interfacial strain in epitaxial multilayers of antiferroelectric PbZrO3 and relaxor‐ferroelectric Pb0.9La0.1Zr0.52Ti0.48O3 is shown to significantly enhance the maximum polarization of the multilayer thin‐film capacitors, beyond that of the composing individual layers. Insights obtained from atomically resolved energy‐dispersive X‐ray spectroscopy and high‐resolution X‐ray diffraction analysis of the interface and domain structure are used to develop phenomenological models that explain the observed trends in breakdown strength and energy‐storage density as a function of multilayer period number. The underlying mechanism is the mechanical coupling between the layers that depends on the individual layer thicknesses. These factors result in a strongly enhanced recoverable energy‐storage density (increased by a factor of 4 to ≈128.4 J cm−3) with high efficiency (≈81.2%). Moreover, the multilayer films show almost fatigue‐free energy‐storage performance after 1010 switching cycles, even at elevated temperatures up to 220 °C, demonstrating their robustness. The outstanding properties show the great potential of epitaxial multilayers for energy‐storage applications, due to the well‐defined separate layers and coupling of properties across the interfaces, not present in ceramic composites.
