Capacitors are widely used as energy storage elements in electric vehicles (EVs) and pulsed power. At present, it is still challenging to develop capacitor dielectrics with good energy storage and discharge performance. In this work, antiferroelectric (AFE) ceramics (Pb0.94La0.04)[(Zr0.6Sn0.4)0.92Ti0.08]O3 with enhanced antiferroelectricity were fabricated by a rolling process. The obtained ceramics have a high recoverable energy density of 5.2 J/cm3 and an extremely high efficiency of 91.2% at 327 kV/cm. The ceramics have good energy storage and discharge performance in the temperature range from −40°C to 100°C due to the existence of AFE phase. An energy density of 3.7 J/cm3 can be released at 200 kV/cm in less than 500 ns and the discharge current keeps stable after 1000 charge‐discharge cycles. By direct short experiment, a current density of 1657 A/cm2, which is the highest result in recently developed AFE ceramics, and a power density of 228 MW/cm3 were achieved. The possibility of using AFEs at low temperature was confirmed. The excellent energy storage and discharge performance prove the great potential of the obtained ceramics in high energy and power density 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.

“…The results can prove that the 0.85NBT-0.15CZT ceramics have an outstanding temperature stability during the charge-discharge process, as discussed above. Table 2 exhibits the comparison of the applied electric field, t 0.9 and P D between the 0.85NBT-0.15CZT ceramics, and some other reported ceramics, 9,[42][43][44][45] which indicates that NBT-CZT ceramics have the fast discharge speed and high power density, and it is very significant for application in pulsed power capacitors.

Lead-free ferroelectric ceramics are very suitable for electrostatic energy storage capacitors due to their outstanding characteristics of high charge-discharge speed, high power density, and environmental friendliness. Herein, a novel material system as (1−x)Na 0.5 Bi 0.5 TiO 3-xCaZr 0.5 Ti 0.5 O 3 (NBT-CZT, x = 0, 0.05, 0.10, 0.12, 0.15, and 0.20) was designed and prepared for dielectric energy storage ceramics. It demonstrated that the CZT additives induced a phase transition for the NBT ceramics, from ferroelectric to relaxor ferroelectric. In particular, extremely high stored energy storage density (6.92 and 5.37 J/cm 3), high recoverable energy storage density (4.77 and 4.37 J/cm 3), and moderate efficiency (69.0% and 81.4%) were achieved in both the samples of x = 0.12 and x = 0.15, respectively. The ceramics exhibited excellent stability of energy storage performance covering a wide temperature (25°C-200°C) and frequency (0.5-50 Hz) range, and also fatigue cycles up to 10 5. Additionally, the NBT-CZT ceramics had a fast discharge speed (t 0.9 < 100 ns) and high power density (24.2 MW/cm 3 , E = 100 kV/cm, x = 0.15), and the charge-discharge process remained stable even when the measured temperature was up to 160°C. Therefore, the NBT-CZT ceramics have the potential to be utilized in electrostatic energy storage applications.
