“…However, during the charging–discharging process of the antiferroelectrics, there is a transition from antiferroelectric to ferroelectric, leading to temperature instability and a large volume expansion and cracks at a high applied electric field, which makes short cycle lifetimes . In addition, a large proportion of the antiferroelectrics contain lead, , which reflects badly on environmental conservation. As a result, the lead-free relaxor ferroelectric ceramics based on environment-friendly compositions have attracted significant attention among researchers as energy storage materials because of large P max and small P r values …”

In this study, good energy storage properties are obtained via enhancing dielectric breakdown strength (DBS) in transparent ErBiO 3 (EB)-doped (K 0.5 Na 0.5 )NbO 3 (KNN-xEB) ceramics. The doping of EB makes a strong impact on the grain size and densities of KNN-based ceramics, which decreases the average grain size and enhances the densities significantly. A gradual transformation of crystal structures from orthorhombic to pseudocubic occurs via EB modification. Rietveld refinement is carried out to further investigate the influence of doped EB on the crystal structure, especially on the distortion degree of the pseudocubic phase. The domain structures change from irregular macroscopic and lamellar domains to nanodomains because of the donor doping of EB. The contribution of the second phase to DBS is also confirmed through first-principles calculation on the basis of density functional theory (DFT). The energy storage properties are also investigated with an energy storage density of W ∼ 2.68 J/cm 3 and a recoverable energy storage density of W rec ∼ 1.85 J/cm 3 for the KNN-0.015EB ceramic, which also present a good thermal stability. The results imply that the KNN-xEB ceramics have huge potential for optical and energy storage applications as multifunctional materials.

“…For x = 0.02, the double hysteresis loops measured at 225°C display a relatively high maximum polarization ( P max ) and a very low remnant polarization ( P r ), leading to a good energy storage density of W ~ 1.84 J/cm 3 . With the reducing test temperature, P max exhibits a gradual increase and the value of W could have a appropriate growth, however, P r increases consequently and this will counteract the contribution of P max to the W value. Therefore, the W value increases firstly with the reducing test temperature and reaches a maximum value of 1.98 J/cm 3 at 125°C, then decreases slowly, as shown in the inset of Fig.…”

“…Recently, with the rapid development of the fabrication technology, the energy storage density and the lower costs are permitted significantly . Our recent work shows that the energy storage density of PLN ceramics has been up to 1.95 J/cm 3 . On the other hand, the electrical properties of the lead‐based perovskite AFE materials can be modified by addition of rare earth element, such as lanthanum .…”

A solid solution of (1−x)Pb(Lu1/2Nb1/2)O3–xPbTiO3 with composition of 0.01 ≤ x ≤ 0.08 have been prepared successfully. XRD analysis indicates the crystal structure adopts an orthorhombic (O) phase in 0.01 ≤ x ≤ 0.06 interval and becomes the coexistence of O and rhombohedral (R) phase at x = 0.07, then turns into R phase mostly at x = 0.08. In addition, two sets of superlattice reflections due to B‐site ordering and antiparallel cation displacement are distinguished by XRD and the superstructures which arise from antiparallel cation displacement disappear gradually with the increasing x. The grain size increases gradually with the increasing x, and then becomes the bimodal microstructure at x ≥ 0.06 due to the coexistence of O and R phase. The dielectric spectra exhibit Curie temperature decreases from 248°C to 147°C with increasing x from 0.01 to 0.08. As 0.01 ≤ x ≤ 0.04, the samples display typical double hysteresis loops, suggesting antiferroelectric nature, then turn into ferroelectric gradually at x = 0.05. Finally, it exhibit typical ferroelectric hysteresis loops in 0.06 ≤ x ≤ 0.08 interval.

“…In recent years, antiferroelectric materials have attracted much attention in the field of high‐density energy storage because they can possess a higher energy storage density during the antiferroelectric‐ferroelectric (AFE‐FE) phase transition . The recoverable energy storage density ( W rec ) of AFE materials can be estimated from the polarization‐electric field ( P ‐ E ) hysteresis loop, and is calculated by the following formula:

<! [C D A T A false[W_{rec} = \int_{P_{r}}^{P_{truemax}} E d P false]] >

where E is the applied field, P max is the maximum polarization, and P r is the remnant polarization.…”

In this work, antiferroelectric Au–PbZrO3 (Au–PZO) nanocomposite thin films were prepared by chemical solution deposition (CSD), and the effects of Au concentration on the antiferroelectric properties and the recoverable energy density were investigated. The results showed that the optimal Au concentration in the Au–PZO nanocomposite thin films was about 1 mol% for structural and electric properties. In the Au–PZO nanocomposite thin films with 1 mol% Au, Au nanoparticles (NPs) were distributed uniformly in the perovskite PZO matrix. Moreover, the recoverable energy density was 10.8 J/cm3 at 600 kV/cm, which is 42% higher than that of the pure PZO films. The results demonstrate that adding an appropriate amount of noble metal NPs in antiferroelectric thin films is an effective method to improve the energy storage properties.
