“…In previous studies, several methods have been demonstrated to be able to efficiently lower the sintering temperature of ceramic materials, including adding glass additives, [54,[134][135][136] doping low melting point oxides or compounds [137][138][139] and using a twostep sintering method.

“…Last but not least, using special synthesis techniques such as SPS, [117] wet-chemical, [105] and two-step sintering, [118,119] shows that the energy storage properties of BNT-BT based ceramics can be further enhanced due to the improvement of sample volume density and increased dielectric breakdown strengths. It is reported that the breakdown strength of BNT-BT-KN ceramics can be improved from 8.85 kV/mm by conventional solid-state sintering method to 16.77 kV/mm if fabricated by the wet-chemical method.…”

“…[140] Based on the two-step sintering method, much work has been performed to synthesize ceramics with fine-grain and homogeneous microstructures at lower sintered temperatures. [118,119,148] For example, though heating at 1140 o C without heat preservation and then directly cooling down to 1000 o C at a rate of 20 o C/min and maintaining for 5 h, dense and uniform 0.89Bi 0.5 Na 0.5 TiO 3 -0.06BaTiO 3 -0.05K 0.5 Na 0.5 NbO 3 ceramics can be prepared. [119] And the two-step sintered sample showed improved electric performance with a low remanent polarization of 5.4 µC/cm 2 and a high breakdown strength of 10 kV/mm, resulting in a relatively large energy storage density of 0.90 J/cm 3 , which is two times higher than that of single-step sintered sample.…”

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.

“…29 Several reports have demonstrated that binary NBT-xST ceramic bulks will present relaxor-ferroelectric characteristics at room temperature when x ‚ 0:26. [30][31][32] These indicated that NBT-xST whiskers appear to be promising for applications in high discharged energy density polymer-based capacitors. In our previous study, 33 NBT-xST (x ¼ 0, 0.10, 0.26) whiskers have been successfully synthesized by a two-step molten salt method using Na 2 Ti 6 O 13 whiskers as templates.…”

The high-performance energy-storage dielectric capacitors are increasingly important due to their wide applications in high power electronics. Here, we fabricated a novel P(VDF-HFP)-based capacitor with surface-modified NBT-[Formula: see text]ST ([Formula: see text], 0.10, 0.26) whiskers, denoted as Dop@NBT-[Formula: see text]ST/P(VDF-HFP). The influences of ST content, fillers’ volume fraction and electric field on the dielectric properties and energy-storage performance of the composites were investigated systematically. The results show that the dielectric constant monotonously increased with the increase of ST content and fillers’ volume fraction. The composite containing 10.0 vol% NBT-0.26ST whiskers possessed a dielectric constant of 39 at 1[Formula: see text]kHz, which was 5.6 times higher than that of pure P(VDF-HFP). It was noticed that the D-E loops of the composites became thinner and thinner with the increase of ST content. Due to the reduced remnant polarization, the composite with 5.0 vol% NBT-0.26ST whiskers achieved a high energy density of 6.18[Formula: see text]J/cm3 and energy efficiency of approximately 57% at a relatively low electric field of 200[Formula: see text]kV/mm. This work indicated that NBT-0.26ST whisker is a kind of potential ceramic filler in fabricating the dielectric capacitor with high discharged energy density and energy efficiency.

A new type of (0.7−x)Bi0.5Na0.5TiO3‐0.3Sr0.7Bi0.2TiO3‐xLaTi0.5Mg0.5O3 (LTM1000x, x = 0.0, 0.005, 0.01, 0.03, 0.05 wt%) lead‐free energy storage ceramic material was prepared by a combining ternary perovskite compounds, and the phase transition, dielectric, and energy storage characteristics were analyzed. It was found that the ceramic materials can achieve a stable dielectric property with a large dielectric constant in a wide temperature range with proper doping. The dielectric constant was stable at 2170 ± 15% in the temperature range of 35‐363°C at LTM05. In addition, the storage energy density was greatly improved to 1.32 J/cm3 with a high‐energy storage efficiency of 75% at the composition. More importantly, the energy storage density exhibited good temperature stability in the measurement range, which was maintained within 5% in the temperature range of 30‐110°C. Particularly, LTM05 show excellent fatigue resistance within 106 fatigue cycles. The results show that the ceramic material is a promising material for temperature‐stable energy storage.
