“…Although lead-based ferroelectric materials can meet these conditions, Pb is extremely unrecoverable and harmful to both humans and the environment. − Therefore, there is an urgent need to explore lead-free ceramic materials that can effectively meet these conditions. Na 0.5 Bi 0.5 TiO 3 (NBT)-based ceramics hold tremendous promise for energy storage applications because of their large P max . − However, their high P r and low breakdown field strength ( E B ) limit practical application of these materials. To solve these problems, Li et al successfully improved the W rec and η of NBT ceramics by engineering A-site vacancy defects by compositing a Sr 0.7 Bi 0.2 TiO 3 compound .…”

Lead-free (1 − x)(0.94Na 0.5 Bi 0.5 TiO 3 -0.06BaTiO 3 )-x(Sr 0.85 Bi 0.1 )-(Mg 1/3 Nb 2/3 )O 3 ((1 − x)(NBT-BT)-xSBMN) ceramics are synthesized using the traditional solid-state reaction method. The introduction of SBMN leads to a dense microstructure with small mean grain size. The temperature-dependent dielectric spectrum reveals that the sample with x = 0.24 shows the best temperature stability with T S occurring around room temperature. A large recoverable energy storage density value of 3.05 J/cm 3 , high efficiency of 89%, and excellent temperature (25− 140 °C)/frequency (1−100 Hz) stabilities are simultaneously achieved in the ceramic. The variation of recoverable energy storage density is less than 7% in the temperature range of 25−140 °C. The ceramic also has a high power density of 67.86 MW/cm 3 .

Dielectric capacitors reveal great potential in the application of high power and/or pulsed power electronic devices owing to their ultrafast charge-discharge rate and ultrahigh power density. Among various dielectric capacitors, the environment-friendly lead-free dielectric ceramics have drawn extensive investigations in recent years. Nevertheless, the relatively small recoverable energy storage density (W rec ) is still an obstacle for their application. Herein, the (0.55−x)BiFeO 3 -0.45SrTiO 3 -xBaTiO 3 ternary ceramics with 0.1 wt% MnO 2 were prepared by the solid-state reaction, and achieved enhanced relaxor behavior as well as breakdown strength E b . As a result, the x = 0.12 ceramic exhibited superior comprehensive energy storage performance of large E b (50.4 kV/mm), ultrahigh W rec (7.3 J/cm 3 ), high efficiency η (86.3%), relatively fast charge-discharge speed (t 0.9 = 6.1 μs) and outstanding reliability under different frequency, fatigue, and temperature, indicating that the BiFeO 3 -based relaxor ferroelectric ceramics are prospective alternatives for electrostatic energy storage.

“…Liu et al reported that 0.95BaTiO 3 –0.05Bi(Mg 0.5 Ti 0.5 )O 3 –0.03Sm possesses a W rec of 3.86 J/cm 3 with a η of 81.8% at 220 kV/cm . Although there are some reports of obtaining high W rec and high η simultaneously, these works account for a small proportion. − This indicates that it is relatively difficult to obtain Bi 0.5 Na 0.5 TiO 3 - and BaTiO 3 -based ceramics with high energy storage efficiency due to the high P r and coercive field of Bi 0.5 Na 0.5 TiO 3 and BaTiO 3 . In addition, for Bi 0.5 Na 0.5 TiO 3 - and BaTiO 3 -based ceramics, the research of the evolution process from the ferroelectric phase to the relaxor ferroelectric phase and the related energy storage mechanism are relatively mature.…”

Sr 0.7 Bi 0.2 TiO 3 (SBT) is a promising pulse energy storage material due to minor hysteresis, but its low maximum polarization (P max ) is bad for energy storage. K + −Bi 3+ defect pairs were introduced into the A-site of SBT to obtain Sr 0.35 Bi 0.35 K 0.25 TiO 3 (SBKT) with larger P max . Through firstprinciples calculations, we determined that the introduction of defect pairs destroys the paraelectric order phase and increases local polarization, resulting in more and larger polar nanoregion (PNR) formation. On this basis, doping NaNbO 3 (NN) in A-and B-sites of SBKT increases the cationic disorder and ferroelectric destabilization, further destroying the long-range order structure and forming more PNRs with smaller sizes. This enhances relaxation and decreases remnant polarization, and the broadened dielectric peak enables 0.85SBKT−0.15NN to meet the X7R specification. Furthermore, the decreased grain size and oxygen vacancy, increased thermal conductivity, and weakened local electric field (simulated by COMSOL) increase the dielectric breakdown strength (BDS). As a result, 0.95SBKT−0.05NN exhibits a high energy storage density (W) of 2.45 J/cm 3 with a high efficiency of 93.1%, a high pulsed discharge energy density of 2.1 J/cm 3 , and a high power density of 54.1 MW/cm 3 at 220 kV/cm. The energy storage properties show excellent stability of temperature (−55 to 150 °C), frequency (10−500 Hz), and cycling (10 5 cycles). Notably, for the pulse charge−discharge properties, 0.95SBKT−0.05NN shows great fatigue resistance during 10 5 cycles under 25 and 150 °C, accompanied by excellent thermal stability. Moreover, the BDS and P max of 0.95SBKT−0.05NN sintered in O 2 further enhance. A higher W of 2.92 J/cm 3 with a high efficiency of 89% at 250 kV/cm is achieved. Therefore, 0.95SBKT−0.05NN shows great application potential for pulse energy storage. In this work, we provide a novel strategy and systematic in-depth study for improving the energy storage properties of SBT.
