“…In this regard, slim P-E hysteresis loops with as high P s and low P r as possible should be desirable to achieve both high energy storage density and efficiency [8]. Bismuth sodium titanate (Bi 0.5 Na 0.5 TiO 3 , BNT) shows normal ferroelectric behavior with a very large saturated polarization (P s > 40 μC/cm 2 ) [9]. However, BNT also has a very large remnant polarization (P r ≈ 38 μC/cm 2 ), which makes its P-E hysteresis loop showing fat shape unsatisfied for energy storage applications [10].…”

“…However, BNT also has a very large remnant polarization (P r ≈ 38 μC/cm 2 ), which makes its P-E hysteresis loop showing fat shape unsatisfied for energy storage applications [10]. In recent years, BNT modifications, such as doped by (Sr,Bi)TiO 3 (SBT), (K,Na)NbO 3 (KNN), or SrTiO 3 (ST), have been extensively studied to reduce its P r markedly and enhance breakdown strength, thus achieving high recoverable energy density [9,[11][12][13][14][15][16][17]. Meanwhile, BNT is lead-free, which is highly expected to replace the widely used relaxor ferroelectric Pb-containing systems in ceramic capacitor applications [18].…”

Ba 0.3 Sr 0.7) x (Bi 0.5 Na 0.5) 1-x TiO 3 (BS x BNT, x = 0.3-0.8) ceramics were prepared to investigate their structure, dielectric and ferroelectric properties. BS x BNT ceramics possess pure perovskite structure accompanied from a tetragonal symmetry to pseudo-cubic one with the increase of x value, being confirmed by X-ray diffraction (XRD) and Raman results. The T m corresponding to a temperature in the vicinity of maximum dielectric constant gradually decreases from 110 ℃ (x = 0.3) to-45 ℃ (x = 0.8), across T m = 36 ℃ (x = 0.5) with a maximum dielectric constant (ɛ r = 5920 @1 kHz) around room temperature. The saturated polarization P s gradually while the remnant polarization P r sharply decreases with the increase of x value, making the P-E hysteresis loop of BS x BNT ceramics goes slim. A maximum difference between P s and P r (P s-P r) is obtained for BS x BNT ceramics with x = 0.5, at which a high recoverable energy density (W rec = 1.04 J/cm 3) is achieved under an applied electric field of 100 kV/cm with an efficiency of  = 77%. Meanwhile, the varied temperature P-E loops, fatigue measurements, and electric breakdown characteristics for the sample with x = 0.5 indicate that it is promising for pulsed power energy storage capacitor candidate materials.

materials (FE), relaxor ferroelectric materials, and antiferroelectric materials (AFEs). [2][3][4][5][6][7] Among them, antiferroelectric materials are preferred candidates for obtaining an exceptional energy storage density due to the high saturation polarization (P s ) and zero remnant polarization (P r ). [7] A schematic illustration of the energy storage mechanism of antiferroelectric materials is shown in Figure S1 in the Supporting Information. The W tot and W rec of antiferroelectrics are calculated by the area between the phase switching loop and the polarization axis and can be described by the following equations [7,8] where P max , P r , and E represent the maximum polarization, the remnant polarization, and applied electric field, respectively. The difference between W rec and W tot represents the energy dissipation (W loss ) and the ratio of W rec to W tot is defined as the energy efficiency, which can be described by the following equation [7,8] 100% 100% rec tot rec rec l ossIn comparison with lead-free antiferroelectric ceramics, PbZrO 3 -based antiferroelectric ceramics have always been a more popular topic because of their superior energy storage performance. It is particularly interesting that a minor variation of doping ions at the A or B site of the perovskite (ABO 3 ) structure may display huge differences in materials properties. Hence, scholars have continuously focused on investigating the structure-property relationships of PbZrO 3 -based AFE ceramics, such as tailoring the phase transition characteristics of AFE ceramics via ions doping, or utilizing unique fabrication methods to increase the energy storage density, and so forth. [8][9][10][11][12] Recently, a record-high recoverable energy storage density of 11.18 J cm −3 was obtained in Sr-doped (Pb 0.94 La 0.02 Sr 0.04 )(Zr 0.9 Sn 0.1 ) 0.995 O 3 AFE ceramics that prepared by tape-casting method. [9] However, the large electrical hysteresis resulted from the first-order antiferroelectric-ferroelectric (AFE-FE) phase transition has always been an apparent drawback of AFE ceramics, [13] leading to the high energy dissipation, Antiferroelectric ceramics with extraordinary energy-storage density have gained exponentially soaring attention for their applications in pulsed power capacitors. Nevertheless, high energy dissipation is a deficiency of antiferroelectric materials. The modulation of Ba/La-doped (Pb 0.91 Ba x La 0.06−2x/3 ) (Zr 0.6 Sn 0.4 )O 3 (x = 0.015, 0.03, 0.045, 0.06) antiferroelectric ceramics is aimed at increasing the energy efficiency and obtaining an ideal energy storage density. The traditional solid-state reaction is exploited for ceramics fabrication and all prepared samples exhibit an ultralow electrical hysteresis due to the local structural heterogeneity, as verified by Raman spectroscopy. Of particular importance is the fact that the (Pb 0.91 Ba 0.045 La 0.03 )(Zr 0.6 Sn 0.4 ) O 3 ceramic possesses an excellent recoverable energy storage density (W rec = 8.16 J cm −3 ) and a remarkable energy efficiency (η = 92.1...

Lead‐free dielectrics with both excellent strain behavior and superior energy‐storage feature are crucial toward providing desired performance for smart electrical devices, especially under harsh environmental conditions. Herein, it is demonstrated that giant strain response of ≈0.51% with small hysteresis of ≈29% and large recoverable energy density (≈1.6 J cm−3) under low electric field (120 kV cm−1), together with excellent stabilities against temperature, frequency, and cycling, can be simultaneously achieved in oriented (with 79.4% 〈00l〉 texture) (Bi0.5Na0.5)TiO3–BaTiO3–NaNbO3 (BNT–BT–NN) ceramics through integrating crystallographic texturing and domain engineering. Besides, a fast discharge rate of <0.1 µs along with good thermal endurance in a wide temperature range can also be acquired. It is uncovered by piezoelectric force microscopy measurements that the formation of oriented microstructure greatly promotes the domain switching and mobility, producing the considerably easy ergodic relaxor to ferroelectric phase transition with concurrently improved strain and energy storage properties in grain orientation controlled BNT–BT–NN ceramics. This study offers a feasible and propagable guidance, i.e., crystallographic texturing and domain engineering, to develop new lead‐free dielectrics for both actuators and capacitors.
