“…While the significant polarization contribution from defect-dipole clusters together with intrinsic polarization leads to an at least two-time enhancement in P max . Therefore, compared with the previous approaches of single-doping and solid solution, 38 the A−B site co-doping strategy can simultaneously enhance P max and E b . Since this co-doping strategy is flexible to be used in other ABO 3 perovskite antiferroelectrics and ferroelectrics, the approach is believed to inspire further optimization of their energy storage performances.…”

Antiferroelectric materials are promising to be used for power capacitive devices. To improve the energy storage performance, solid-solution and defect engineering are widely used to suppress the long-range order by introducing local heterogeneities. However, both methods generally deteriorate either the maximum polarization or breakdown electric field due to damaged intrinsic polarization or increased leakage. Here, we show that forming defect-dipole clusters by A−B site acceptor−donor co-doping in antiferroelectrics can comprehensively enhance the energy storage performance. We took the La−Mn co-doped (Pb 0.9 Ba 0.04 La 0.04 )(Zr 0.65 Sn 0.3 Ti 0.05 )O 3 (PBLZST) as an example. For co-doping with unequal amounts, high dielectric loss, impurity phase, and decreased polarization were observed. By contrast, La and Mn in an equal amount of co-doping can significantly improve the overall energy storage performance. An over 48% increasement in both the maximum polarization (62.7 μC/cm 2 ) and breakdown electric field (242.6 kV/cm) was obtained in 1 mol % La and 1 mol % Mn equally co-doped PBLZST, followed by a nearly two-time enhancement in W rec (6.52 J/cm 3 ) compared with that of the pure matrix. Moreover, a high energy storage efficiency of 86.3% with an enhanced temperature stability over a wide temperature range can be achieved. The defect-dipole clusters associated with charge-compensated co-doping are suggested to contribute to an enhanced dielectric permittivity, linear polarization behavior, and maximum polarization strength compared with that of the unequal co-doping cases. The defect-dipole clusters are suggested to couple with the host, leading to a high energy storage performance. The proposed strategy is believed to be applicable to modify the energy storage behavior of antiferroelectrics.

“…Meanwhile, Figure d shows the fluctuation of the current density ( C D ) and power density ( P D ) of the x = 0.03 composition ceramic at various electric fields. C D and P D can be obtained by the following formulas: C D = I max S P D = E I max 2 S where S stands for the electrode cross-sectional area and E for the electric field. As can be seen, as the electric field is increased, C D and P D gradually rise.…”

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.

“…Moreover, in recent years, researchers have begun to pursue high performance at the same time as well as high temperature stability because of the requirements for commercial applications of capacitors in different working environments 2,12–15 .

(Pb, La)(Zr, Ti)O3 antiferroelectric (AFE) materials are promising materials due to their energy‐storage density higher than 10 J cm−3, but their low energy‐storage efficiency and poor temperature stability limit their application. In this paper, the (1 − x)(Pb0.9175La0.055)(Zr0.975Ti0.025)O3–xPb(Yb1/2Nb1/2)O3 (PLZTYN100x) AFE ceramics were prepared via two‐step sintering method and investigated thoroughly. With the doping of Yb3+ and Nb5+, the phase structure transforms from the orthorhombic phase (AFEO) to the coexistence of the orthorhombic‐and‐tetragonal phases. This structure reduces the free energy difference between the AFE and ferroelectric phases and reduces the fluctuation of energy with temperature, improving the energy storage efficiency and temperature stability. When the x = 0.05 (PLZTYN5), the AFE ceramic exhibits excellent temperature stability and ultrahigh energy storage performance, whose recoverable energy density (Wrec) is 6.8–8.2 J cm−3 at 30 kV mm−1 in the temperature range from −55 to 75°C, and efficiency (ƞ) is 78%–86.7%. In addition, the change of Wrec is less than 15%, exceeding the performance of most AFE ceramics. The results demonstrate that the PLZTYN5 ceramic has great potential in pulse power capacitors.
