“…Compared with our previous study on BNTSZNN ceramics (2.46 J/cm 3 at 220 kV/cm), there is a qualitative leap in the energy storage properties here, as the discharge energy density and breakdown strength increased by 126 and 59%, respectively (marked by the red arrow in Figure c). A comparison of the energy storage performances of recently reported ceramic systems (BaTiO 3 (BT)-based, − K 0.5 Na 0.5 NbO 3 (KNN)-based, ,,− Bi 0.5 Na 0.5 TiO 3 (BNT)-based, ,− and AgNbO 3 (AN)-based − ) is summarized in Figure c as well. There are rarely lead-free bulk ceramics that have achieved a discharge energy density greater than 4 J/cm 3 , accompanied with a small breakdown strength below 300 kV/cm.…”

Dielectric ceramics are crucial for high-temperature, pulse-power energy storage applications. However, the mutual restriction between the polarization and breakdown strength has been a significant challenge. Here, multiphase engineering controlled by the two-step sintering heating rate is adopted to simultaneously obtain a high polarization and breakdown strength in 0.8(0.95Bi 0.5 Na 0.5 TiO 3 − 0.05SrZrO 3 )−0.2NaNbO 3 (BNTSZNN) ceramic systems. The coexistence of tetragonal (T) and rhombohedral (R) phases benefits the temperature stability of BNTSZNN ceramics. Increasing the heating rate during sintering reduces the diffusion of SrZrO 3 and NaNbO 3 into Bi 0.5 Na 0.5 TiO 3 , which results in a high proportion of the R phase and a finer grain size. The overall polarization is enhanced by increasing the proportion of the high-polarization R phase, which is demonstrated using a first-principles method. Meanwhile, the finer grain size enhances the breakdown strength. Following this design philosophy, an ultrahigh W dis of 5.55 J/cm 3 and η above 85% is achieved in BNTSZNN ceramics as prepared with a fast heating rate of 60 °C/min given a simultaneously high polarization of 43 μC/cm 2 and high breakdown strength of 350 kV/cm. Variations in the discharge energy density from room temperature to 160 °C are less than 10%. Additionally, such BNTSZNN ceramics exhibit an ultrafast discharge speed with τ 0.9 at approximately 60 ns, which shows great potential in pulse-power system applications.

Featured with high polarization and large electric field‐induced phase transition, PbZrO3‐based antiferroelectric (AFE) materials are regarded as prospective candidates for energy‐storage applications. However, systematical studies on PbZrO3‐based materials are insufficient because of their complex chemical compositions and various phase structures. In this work, (Pb0.94La0.04)(Zr1‐x‐ySnxTiy)O3 (abbreviated as PLZST, 0 ≤ x ≤ 0.5, 0.01 ≤ y ≤ 0.1) AFE system was selected and the energy‐storage behavior was regulated. It is found that low Ti content benefits to obtain satisfactory electric breakdown strength, realizing high energy‐storage density. With Sn content increasing, the electric hysteresis decreases gradually, which is beneficial to improve energy conversion efficiency. As a result, a large recoverable energy‐storage density of 9.6 J/cm3 and a high energy conversion efficiency of 90.2% were achieved in (Pb0.94La0.04)(Zr0.49Sn0.5Ti0.01)O3 ceramic. This work reveals energy‐storage behavior of PLZST AFE materials systematically, providing reference for performance tailoring and new material designing in energy‐storage applications.

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.
