“…Compared with macroscopic property investigation, in situ dynamic structure study lags far behind in the field of dielectric capacitors. An important reason lies in the fact that there exists a large mismatch between the structural response time for energy storage [47] and the data collection time [48][49][50]. For the former, this is usually completed at the millisecond scale or within an even shorter time.…”

Benefitting from exceptional energy storage performance, dielectric-based capacitors are playing increasingly important roles in advanced electronics and high-power electrical systems. Nevertheless, a series of unresolved structural puzzles represent obstacles to further improving the energy storage performance. Compared with ferroelectrics and linear dielectrics, antiferroelectric materials have unique advantages in unlocking these puzzles due to the inherent coupling of structural transitions with the energy storage process. In this review, we summarize the most recent studies about in-situ structural phase transitions in PbZrO3-based and NaNbO3-based systems. In the context of the ultrahigh energy storage density of SrTiO3-based capacitors, we highlight the necessity of extending the concept of antiferroelectric-to-ferroelectric (AFE-to-FE) transition to broader antiferrodistortive-to-ferrodistortive (AFD-to-FD) transition for materials that are simultaneously ferroelastic. Combining discussion of the factors driving ferroelectricity, electric-field-driven metal-to-insulator transition in a (La1−xSrx)MnO3 electrode is emphasized to determine the role of ionic migration in improving the storage performance. We believe that this review, aiming at depicting a clearer structure–property relationship, will be of benefit for researchers who wish to carry out cutting-edge structure and energy storage exploration.

“…[9] Anti-ferroelectric ceramics (such as PbTiO 3 -and Pb(Zr,Ti)O 3 -based dielectrics) display double polarization-electric field (P-E) loops, which have tremendous potential for realizing high energy density. [10][11][12] However, most of these materials are Pbbased, whose toxic nature causes a series of environmental problems. Thus, leadfree ceramics have attracted considerable attention as a replacement to Pb-based materials.…”

capacitors), dielectric capacitors are promising candidates for advanced pulsed power applications owing to their high power density and fast charge/discharge speed. [6][7][8] Ceramic dielectrics show excellent temperature stability and mechanical robustness, are promising materials for use in extreme conditions. [9] Anti-ferroelectric ceramics (such as PbTiO 3 -and Pb(Zr,Ti)O 3 -based dielectrics) display double polarization-electric field (P-E) loops, which have tremendous potential for realizing high energy density. [10][11][12] However, most of these materials are Pbbased, whose toxic nature causes a series of environmental problems. Thus, leadfree ceramics have attracted considerable attention as a replacement to Pb-based materials. [7,[13][14][15][16][17][18] Until now, the low energy storage performance (low energy storage density of <4 J cm −3 and/or inferior efficiency of <80%) of lead-free ceramic capacitors hardly meet the increasing integration and miniaturization requirements. [19][20][21][22] Thus, it is imperative to improve the energy storage performance of lead-free ceramic capacitors.As shown in the schematic of Figure 1a, the energy storage density and efficiency of the dielectric capacitors are governed by the maximum polarization (P max ), remanent polarization (P r ), and dielectric breakdown strength (E BDS ). The combination of a large P max , small P r , and high E BDS is essential for realizing ultrahigh energy storage density and efficiency. Considering that the energy loss density (W loss ) is an inevitable part of ferroelectric ceramics, the recoverable energy storage density (W rec ) and energy efficiency (η) are key parameters for evaluating the energy storage performance of nonlinear dielectric ceramic capacitors. [9,17,23] It has been reported that BiFeO 3 (BF) possesses very high spontaneous polarization (≈100 µC cm −2 ), which is superior to most perovskite ferroelectrics, including BaTiO 3 , Bi 0.

“…, where R A and R B are the ionic radii of the A and B site cations, and R O is the ionic radius of oxygen anion. [32][33][34] It is clear that antiferroelectricity gradually increases with decreasing t. Thus, the reducing the A-site ion radius or increasing the B-site ion radius is benecial to stabilizing the antiferroelectricity. For instance, Liu et al found that the AFE-FE phase transition (E F ) and AFE-FE phase transition eld (E A ) of Mn-doped (Pb 0.87 Ba 0.1 La 0.02 ) (Zr 0.65 Sn 0.3 Ti 0.05 )O 3 ceramics increased from 11.9 to 12.8 kV mm À1 and from 7.6 to 9.3 kV mm À1 , respectively, realizing a W rec of 2.64 J cm À3 .…”
