“…49 Larger intensity for Sn 3d 3/2 and Sn 3d 5/2 peaks for Sn 2+ –Fe 2 O 3 indicates larger Sn content incorporated in comparison to Sn 4+ –Fe 2 O 3 . A Na KL1 Auger peak is observed to appear at 496.4 eV for Sn 4+ –Fe 2 O 3 , 50 which suggests that Sn ion is incorporated into the Sn 4+ –Fe 2 O 3 lattice as well. High-resolution XPS spectra of O1s are shown in Fig.…”

“…Furthermore, introducing B‐site complex ions has improved the symmetry of off‐center crystals, disrupted long‐range ferroelectric order, and formed polar nanoregions (PNRs). These PNRs, unlike ferroelectric domains, disappear quickly when the electric field is removed, resulting in lower residual polarization ( P r ) 34–37 …”

Although lead‐free dielectric ceramics have been widely studied to obtain excellent dielectric properties and good energy storage properties, the primary challenge of low energy storage density has not yet been resolved. Here, we introduce the concept of crossover relaxor ferroelectrics, which represent a state intermediate between normal ferroelectrics and relaxor ferroelectrics, as a solution to address the issue of low energy density. The (1−x)BaSrTiO3−xBi(Zn1/2Ti1/2)O3 (x = 0,.05, .1, .15, .2) ceramics were prepared by a solid‐state method. Remarkably, 0.85BST–0.15BZT ceramics achieved a high recoverable energy density (Wrec) of 2.18 J/cm3 under an electric field of 240 kV/cm. BST–BZT materials exhibit substantial recoverable energy density, high breakdown strength, and superior energy efficiency, positioning them as a promising alternative to meet the diverse demands of high‐power applications.

“…Owing to the problems of environment pollution and the energy crisis, the development of new environmentally friendly energy materials is necessary. − Among the energy-storage materials that can be used in pulsed power systems, dielectric ceramics have enormous advantages in power density and discharge time. − Yet a relatively low electric breakdown strength of dielectric ceramics limits their further breakthrough of energy density. − Therefore, it is crucial to obtain dielectric ceramics with a high energy density for practical applications. The total energy density ( W tot ), recoverable energy density ( W rec ), energy efficiency (η), and energy loss ( W loss ) of dielectric ceramics can be calculated using the following formulas: − W tot = ∫ 0 P normalmax E d P W rec = ∫ P normalr P normalmax E d P η = W rec W tot W loss = W tot …”

Relaxor ferroelectric materials have received increasing attention in pulse power devices due to the high power density and rapid charge−discharge capability. However, challenges exist in relaxor ferroelectric behavior because of their low electric breakdown strength. In this article, a large recoverable energy density of 5.94 J/cm 3 , together with a high energy efficiency of 86.9%, is achieved synchronously in La-(Mg 2/3 Nb 1/3 )O 3 (LMN) modified Bi 0.5 Na 0.5 TiO 3 -Sr 0.7 Sm 0.2 TiO 3 (BNT-SST) ceramic. It is suggested that the addition of LMN reduces the grain size and enhances the electrical homogeneity, which boosts the electric breakdown strength of sample ceramics. In addition, in 0.03LMN modified 0.97(BNT-SST) ceramic, a good discharge energy density of 3.9 J/cm 3 and a transient discharge time of 65 ns are attained. Meanwhile, the outstanding stability in the temperature range of 20−100 °C and frequency range of 1−100 Hz is observed in the above component. These results indicate that BNT-SST-LMN ceramic has potential as an energy-storage medium.
