Materials exhibiting high energy/power density are currently needed to meet the growing demand of portable electronics, electric vehicles and large-scale energy storage devices. The highest energy densities are achieved for fuel cells, batteries, and supercapacitors, but conventional dielectric capacitors are receiving increased attention for pulsed power applications due to their high power density and their fast charge–discharge speed. The key to high energy density in dielectric capacitors is a large maximum but small remanent (zero in the case of linear dielectrics) polarization and a high electric breakdown strength. Polymer dielectric capacitors offer high power/energy density for applications at room temperature, but above 100 °C they are unreliable and suffer from dielectric breakdown. For high-temperature applications, therefore, dielectric ceramics are the only feasible alternative. Lead-based ceramics such as La-doped lead zirconate titanate exhibit good energy storage properties, but their toxicity raises concern over their use in consumer applications, where capacitors are exclusively lead free. Lead-free compositions with superior power density are thus required. In this paper, we introduce the fundamental principles of energy storage in dielectrics. We discuss key factors to improve energy storage properties such as the control of local structure, phase assemblage, dielectric layer thickness, microstructure, conductivity, and electrical homogeneity through the choice of base systems, dopants, and alloying additions, followed by a comprehensive review of the state-of-the-art. Finally, we comment on the future requirements for new materials in high power/energy density capacitor applications.

Energy storage materials and their applications have long been areas of intense research interest for both the academic and industry communities. Dielectric capacitors using antiferroelectric materials are capable of displaying higher energy densities as well as higher power/charge release densities by comparison with their ferroelectric and linear dielectric counterparts and therefore have greater potential for practical energy storage applications. Over the past decade, extensive efforts have This article is protected by copyright. All rights reserved. 2been devoted to the development of high performance, antiferroelectric, energy storage ceramics and much progress has been achieved. In this review, the current state-of-the-art as regards antiferroelectric ceramic systems, including PbZrO 3 -based, AgNbO 3 -based and (Bi,Na)TiO 3 -based systems, are comprehensively summarized with regards to their energy storage performance. Strategies are then discussed for the further improvement of the energy storage properties of these antiferroelectric ceramic systems. This is followed by a review of the low temperature sintering techniques and the charge-discharge performance of antiferroelectric ceramics from a practical point of view. The review will be of benefit for researchers in the area as it offers a quick overview of recent progress in the development of various kinds of antiferroelectric ceramics and their properties. It should also stimulate the development of novel antiferroelectric ceramics with high energy storage performance.
