Ceramic-based dielectric capacitors have gained prominence in research owing to their high relative permittivity, excellent mechanical properties, and temperature stability. BiFeO 3 -based ceramics have captured significant attention in dielectric capacitors attributable to their high saturation polarization. Yet, the high remanent polarization, as well as the low electric breakdown strength, constrains the improvement of their energy storage performances. Herein, we incorporated the A-/B-site complicated component (La 0.5 Na 0.5 )(Mg 1/3 Nb 2/3 )O 3 into the binary solid solution 0.7BiFeO 3 –0.3BaTiO 3 ceramics with morphotropic phase boundary, to enhance the endurance for electric field and reduce remanent polarization by optimizing relaxor behavior. Consequently, a high recoverable energy density of 8.3 J/cm 3 and a high efficiency of 84.6% under 500 kV/cm were obtained in the preferred composition. These results offer a feasible pathway to exploit the high-performance BiFeO 3 -based ceramics for electrostatic energy storage.

Nowadays, it remains a challenge to achieve a simultaneous improvement of dielectric constant, energy density, and temperature stability in dielectric ceramics . In this work, it was found that such drawback could be effectively resolved by using KTaO 3 to substitute Na 0.5 Bi 0.5 TiO 3 . In (1- x )Na 0.5 Bi 0.5 TiO 3 - x KTaO 3 ceramics, the temperature coefficient of capacitance (TCC) of x = 0.10 composition is lower than 15% in the temperature range of 25–390 °C, with a high dielectric constant of 2008 and a low dielectric loss of 0.0044 at 150 °C. Meanwhile, a large discharged energy density of ~2.50 J/cm 3 with the variation less than± 3% in 5–190 °C was obtained under a low electric field of 18 kV/mm in x = 0.20 composition, accompanied with a high energy efficiency of> 80%. These results reveal that this ceramic system is a promising candidate for temperature-stable dielectric and energy storage capacitors applications.

Piezoelectric ceramics with high strain response and low hysteresis are highly in demand for high-performance actuator applications. Unfortunately, the trade-off relationship between large field-induced strain and low hysteresis in piezoelectric ceramics is a key challenge for designing high-performance piezoelectric actuators. Herein, y mol%La-doped 0.10 Pb(In 1/2 Nb 1/2 )O 3 - x PbZrO 3 -(0.90 – x )PbTiO 3 [0.10PIN- x PZ-(0.90-x)PT: y mol%La] ternary relaxor ferroelectric ceramics were prepared by conventional solid-state reaction technique. Pb(In 1/2 Nb 1/2 )O 3 (PIN) as a relaxor end member was introduced into (Pb,La) (Zr,Ti)O 3 (PLZT) system to improve relaxor characteristics and strain properties. A giant strain of 0.23% was obtained in 0.10PIN-0.59PZ-0.31 PT: 8mol%La ceramic at the electric field of 20 kV/cm, with a high piezoelectric d 33 * of 1150 pm/V and low hysteresis H y of 6.4%, exhibiting a potential application in high-performance piezoelectric actuators. Furthermore, the effects of La ion doping and components on the ferroelectric, dielectric and electric field-induced strain properties were investigated, and provides a new way for improve the strain properties of piezoelectric materials .

(1- x ) (0.99 Na 0.5 Bi 0.5 TiO 3 -0.01BiYbO 3 )- x SrTiO 3 (abbreviated as (1- x ) (0.99NBT-0.01BY)- x STO) ( x = 0.1⁓0.4) relaxor ferroelectric ceramics were fabricated by a solid-state reaction method. The crystal structure, surface morphology as well as dielectric , ferroelectric and energy storage properties of (1- x ) (0.99NBT-0.01BY)- x STO were investigated in detail. X-ray diffraction patterns show that NBT-BY-STO ceramics have a single perovskite structure with a pseudo-cubic phase. The introduction of STO can effectively refine the NBT-based ceramic grain. The relaxation behavior of NBT-BY can be enhanced by incorporating moderate STO, and the impedance reduced with the increase of STO content. The results of hysteresis loop analysis indicate that incorporating STO into NBT-BY contributes to an increase in the electric breakdown field and a reduction in remnant polarization, thus enhancing its energy storage performance significantly. A moderate energy storage property with large W rec (∼2.5 J/cm 3 ) and high η (∼80.97%) was achieved at 260 kV/cm for x = 0.4. Meanwhile, 0.98(0.99NBT-0.01BY)− 0.2STO relaxor ferroelectric ceramic presented relatively good frequency and temperature stabilities of W rec and η . This work provides an effective strategy for enhancing the energy storage performance of NBT-based relaxor ferroelectric ceramics applied in pulsed power devices.

Hybrid electric cars and pulsed power technologies have increased the demand for capacitors with high energy density, wide temperature stability, high operating voltage, and good mechanical qualities. In this work, (1 – x) (0.6Bi0.5K0.5TiO3-0.4BiFeO3)-x(Na0.4Sm0.2NbO3) ((1 – x) (BKTBF)-xNSN) relaxor ceramics were prepared by constructing morphotropic phase boundary (MPB) combined with oxygen vacancy defect engineering. It is worth noting that the 0.6BKT-0.4BFO ceramics at MPB have a high Pmax ∼ 60 μC/cm2. The ultra-hard (HV = 10.7 GPa) BKTBFO-0.16NSN relaxor ferroelectric ceramic achieves a high Wrec of 6.52 J/cm3, a working temperature of 20–120 °C, and a working frequency of 1–1000 Hz. Additionally, the BKTBFO-0.16NSN ceramic demonstrates comprehensive pulse charge–discharge performance (Imax = 17.2 A, CD = 546.7 A/cm2, PD = 54.7 MW/cm3, and t0.9 = 59 ns) and excellent stability (25–125 °C and 104 charge–discharge cycles). This study offers a novel approach for the practical implementation of high-performance pulse capacitors, which will undoubtedly stimulate further research and development of high-Pmax energy storage dielectrics (such as BNT, BKT, and BFO).

Novel lead-free diphasic (1- x )Ba 0.9 Sr 0.1 Ti 0.9 Hf 0.1 O 3 - x Na 0.5 Bi 0.5 TiO 3 (BSTH-NBT) ceramic nanocomposites were synthesized via an economically viable modified mechano-chemical activation technique. In the present investigation, we have developed an energy storage composite material by systematically optimizing the charge transport behavior and charge storage characteristics between the ferroelectric BSTH and piezoelectric NBT phase. The composite with x = 0.09 NBT concentration has shown the best energy storage properties with 1.61 J/cm 3 discharge energy density along with 80.1% energy efficiency. The BSTH and NBT had a synergetic effect on the ferroelectric properties of the composites. The improvement in ferroelectric and piezoelectric properties along with excellent aging characteristics in composite materials is mainly attributed to enhancement in microstructural density, grain boundary interface, and stress effects. The improved dispersibility and excellent compatibility between BSTH and NBT phase have resulted in approximately 20% enhancement in breakdown strength of composite compared to pure BSTH ceramic.

(1- x )Ba 0.65 Bi 0.07 Sr 0.245 TiO 3 - x R 2 O 3 (BBST- x R) ceramics embellished by lanthanides (La, Yb, Gd) were synthesized in this study, and the effects in properties were ascertained. The results show that lanthanides with smaller ionic radius differences and larger relative mass will effectively limit mass transport of other cations and restrain grain growth. It is also found that the paraelectric phase of ceramics can be stabilized by decreasing the ionic radius of lanthanides. In particular, the addition of La unfolds the exceptional recoverable storage density ( W rec ) up to 2.23 J/cm 3 and efficiency ( η ) of ∼76.7% under 280 kV/cm. Finite element simulation and PFM observation also further explain the reasons for the excellent performance. Concurrently, BBST-0.015La ceramic exhibits outstanding thermostability from 30 °C to 150 °C and frequency stabilization from 1 Hz to 300 Hz which indicates the potentiality of application in actual surroundings.

Large energy storage density in relaxor ferroelectrics is commonly accompanied with high breakdown strength, which is adverse to the actual dielectric capacitor applications. We demonstrate that such drawback can be effectively resolved by using Sr 0.7 Bi 0.2 TiO 3 (SBT) to partially replace relaxor ferroelectric 0.76(Bi 0.5 Na 0.5 )TiO 3 -0.24NaNbO 3 (BNT-NN-xSBT). In this study, a high recoverable energy storage density ( W rec ∼3.12 J/cm 3 ) and favorable efficiency ( η ∼75.3 %) are achieved in the BNT-NN-0.1SBT ceramic under a low electric field of 200 kV/cm, which is superior to that of most previously reported dielectric ceramics under the same electric field level. Good temperature stability (25−120 °C), moderate frequency dependence (1−500 Hz), and excellent fatigue resistance (up to 10 5 cycles) are also realized. More interestingly, the indicated ceramics perform high power density ( P D ∼36.40 MW/cm 3 ) and fast discharge time ( t 0.9 ∼0.149 μs) with remarkable temperature endurance. Moreover, of particular significance is that this study offers a feasible guideline to design comprehensive energy storage performance dielectric ceramics for practical applications.

Barium titanate (BaTiO 3 , BT) is widely used in capacitors because of its excellent dielectric properties . However, owing to its high remanent polarisation ( P r ) and low dielectric breakdown field strength ( E b ), achievement of high energy storage performance is challenging. Herein, a systematic strategy was proposed to reduce P r and elevate E b of BT via: (i) modification of the relaxor behavior by alloying it with Bi(Mg 2/3 Ta 1/3 )O 3 (BMT) and (ii) heightening E b by introducing NaTaO 3 (NT) with high band gap. Consequently, the energy storage efficiency ( η ) of 90 % and high E b of 780 kV cm −1 were achieved simultaneously for the BT-BMT- x NT system, which facilitated the recoverable energy density ( W rec ) of 6.02 J cm −3 . At 300 kV cm −1 , its temperature (20–120 °C) and frequency (1–500 Hz) stabilities were found to be good. Moreover, the BT-BMT-0.15NT possessed ultrafast discharge rate ( t 0.9 < 51 ns) and ultrahigh power density ( P D > 94 MW cm −3 ). This study offers an effective strategy for the design of novel high-performance dielectric energy storage materials .

The rapid growth of the electronics industry and increasing concern about environmental issues present great demands for lead-free dielectric ceramic capacitors with remarkable energy storage performances (ESPs). Lead-free perovskite ferroelectric and antiferroelectric systems are deemed as the most promising candidates, and homostructure linear dielectric doping is a widely used strategy to boost ESPs. However, the heavy doping of a linear dielectric usually leads to a great reduction of the polarization, for which an extremely high electric field is needed to achieve a large energy storage density (Wrec). In this study, a Bi0.5N0.5TiO3-SrTiO3 (BNT-ST)-based relaxor ferroelectric system was designed via a heterostructure doping strategy in which a tetragonal tungsten bronze ferroelectric phase Sr2NaNb5O15 (SNN) was introduced into the perovskite matrix. It was found that a small SNN heterostructure doping amount could effectively enhance the relaxor behavior of the BNT-ST ceramic and depress the remnant polarization, while keeping a large maximum polarization. Moreover, the introduction of the tungsten bronze ferroelectric phase obviously decreased the grain size (G) of the BNT-ST ceramic, giving rise to an improved electric breakdown strength (Eb). Finally, a remarkable Wrec of 5.22 J/cm3 and excellent efficiency (η) of 93.87% were attained under a low electric field of 340 kV/cm, which make the Bi0.5N0.5TiO3-SrTiO3-xSr2NaNb5O15 (BNT-ST-xSNN) ceramic system a promising choice for the dielectric energy storage field. These results demonstrate that the heterostructure doping strategy might be a feasible method to develop lead-free perovskite dielectric ceramics with remarkable ESPs under low electric fields.

High-performance dielectric capacitors featuring large recoverable energy storage density (Wrec) and high discharge efficiency (η) are beneficial to realize the device miniaturization, lightweight property, and sustainability of advanced pulse power systems. The obtainment of a high electric breakdown strength (Eb) is crucial for improving the energy storage performance of dielectric materials. However, as for Bi0.5Na0.5TiO3 (BNT) lead-free relaxor ferroelectric ceramics, the relatively lower Eb directly limits their electrical performance improvement and practical applications. Herein, a popular high entropy strategy was employed to rationally design and prepare the (Bi0.5Na0.5)x(Sr0.25Ba0.25La0.25K0.25)(1–x)TiO3 (BNSLBKT-x) lead-free relaxor ferroelectric ceramics based on the BNT matrix. Encouragingly, the BNSLBKT-0.2 high-entropy ceramic exhibits a high Eb of 510 kV/cm, and this can be ascribed to the refined grains and enhanced activation energy. Moreover, it is confirmed that the polar nanoregions (PNRs) exist in the BNSLBKT-0.2 ceramic by the piezoresponse force microscopy (PFM) and transmission electron microscopy (TEM) characteristics, further strengthening relaxation behaviors and decreasing remanent polarization (Pr). It is anticipated that a high Wrec of 4.6 J/cm3 and a good η of 86% are obtained in this BNSLBKT-0.2 high-entropy ceramic. More importantly, the BNSLBKT-0.2 ceramic displays excellent frequency stability of capacitive energy storage at 10–1000 Hz and good temperature stability at 20–140 °C. The fast discharge rate (τ0.9 = 0.26 μs) and the high PD of 49.2 MW/cm are also achieved in this BNSLBKT-0.2 ceramic. The findings demonstrate that this high entropy design is an effective strategy for developing dielectrics with excellent energy storage capability to meet the requirements of modern dielectric capacitor applications.

Piezoelectric materials have wide commercial applications involving our everyday lives. The common categorized “soft” and “hard” piezoelectric materials have distinct even contradictory performance parameters typically exemplified by piezoelectric coefficient d 33 and mechanical quality factor Q m . However, for some special devices operated in resonant mode, simultaneously high or at least balanced performance parameters are needed. Here, we show the transition from “soft” to “hard” performance in 2 mol% Sm doped (0.36- x )Pb(Ni 1/3 Nb 2/3 )O 3 - x Pb(Mn 1/3 Nb 2/3 )O 3 -0.28PbZrO 3 -0.36PbTiO 3 quaternary solid solution piezoceramics, for which the d 33 and planar electromechanical coupling factor k p decrease, while Q m and Curie temperature T c increase monotonously with increasing x value. As the results, balanced performance with moderate d 33 = 446 pC/N, k p = 0.49, Q m = 425, and T c = 170 °C are achieved around x = 0.03. This work not only shows the feasibility for combining “soft” and “hard” performance by forming appropriate solid solutions, but also provides a suitable material basis for further simultaneously optimizing piezoelectric parameters.
