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.

用于储能应用的多层结构电介质的最新进展
静电电容器因其超高的放电功率密度而被广泛应用于许多领域（如高脉冲功率技术、新能源汽车等）。由于介电常数与能量存储密度正相关，因此在过去10年中，将铁电陶瓷掺杂到聚合物中已经取得了显着的进展。然而，这种方法往往会导致介电损耗增加和储能效率降低。因此，利用多层结构来提高电介质储能密度的方式引起了研究人员的关注。尽管利用多层介质的储能特性研究才刚刚开始，但已显示出优异的效果和巨大的潜力。本文介绍了多层结构电介质极化、击穿和储能的主要物理机制，系统总结了理论模拟和实验结果，重点阐述了多层结构电介质的制备方法和设计思路。本文不仅概述了多层结构储能电介质的最新进展，还展望了通过设计多层结构来调节静电电容器的电气性能可能打开另一个窗口的前景。
