“…As shown in Figure 6a, the excellent W r of SQA is justified by its best performance with respect to both the maximum polarization P m and the switching field E sw (the average of forward and backward phase switching fields). However, the W r , P m , and E sw values are smaller than those of the bulk antiferroelectric ceramics and their relaxor modifications, [12][13][14][15][16][17][18][19][20][21][22][38][39][40][41][42][43][44] as evident in Figure 6a and 6b. The magnitude relation of the performance is drastically different in Figure 6c, which is a replot of the data against the stored energy density per weight (W r =8 instead of that per unit volume (W r ).…”

“…In addition, antiferroelectrics can store energy at a high density more effectively than linear dielectrics and ferroelectrics. Especially high performance has been achieved with lead-containing antiferroelectrics, [12][13][14] as exemplified by (Pb,La)(Zr,Ti)O 3 (PLZT) compounds, which have been commercially used in dc link condensers. Also, extensive research has led to remarkable improvements in the electric Please do not adjust margins Please do not adjust margins sheets) of identical polarities.…”

“…As shown in Fig. 3(b), PNZST5-PNZST11 ceramics all exhibit a plateau permittivity peak, distinguishing AFE T , PE MCC , and PE SCC phases [39,40]. And the extra low-temperature permittivity anomaly for PNZST8-PNZST11 ceramics is induced by the FE R -AFE T phase transition.…”

Ferroelectric (FE) phase transition with a large polarization change benefits to generate large electrocaloric (EC) effect for solid-sate and zero-carbon cooling application. However, most EC studies only focus on the single-physical factor associated phase transition. Herein, we initiated a comprehensive discussion on phase transition in Pb 0.99 Nb 0.02 [(Zr 0.6 Sn 0.4 ) 1−x Ti x ] 0.98 O 3 (PNZST100x) antiferroelectric (AFE) ceramic system under the joint action of multi-physical factors, including composition, temperature, and electric field. Due to low energy barrier and enhanced zero-field entropy, the multi-phase coexistence point (x = 0.12) in the composition-temperature phase diagram yields a large positive EC peak of maximum temperature change (ΔT max ) = 2.44 K (at 40 kV/cm). Moreover, the electric field-temperature phase diagrams for four representative ceramics provide a more explicit guidance for EC evolution behavior. Besides the positive EC peaks near various phase transition temperatures, giant positive EC effects are also brought out by the electric field-induced phase transition from tetragonal AFE (AFE T ) to low-temperature rhombohedral FE (FE R ), which is reflected by a positive-slope boundary in the electric field-temperature phase diagram, while significant negative EC responses are generated by the phase transition from AFE T to high-temperature multi-cell cubic paraelectric (PE MCC ) with a negative-slope phase boundary. This work emphasizes the importance of phase diagram covering multi-physical factors for high-performance EC material design.

“…Figure 2b The MCC state is induced by the inhomogeneity of the components resulting from the stochastic distribution of Sn 4+ ion concentrations, which can disrupt the electric field-induced AFE-FE phase transition. 30,31 Previous studies have indicated that this diffusion phase transition behavior facilitates obtaining narrower P−E loops and achieving higher energy storage efficiency. 12,18 With the increase of the Sn 4+ content, the peak temperature range of the MCC dielectric constant becomes wider.…”

PbZrO3-based antiferroelectric (AFE) ceramic materials have emerged as potential candidates for the next generation of high-energy multilayer ceramic capacitors (MLCCs) because of their distinctive characteristics of double hysteresis loops. The energy storage efficiency of orthorhombic AFE ceramics with ultrahigh storage density is relatively low, which hinders their practical application. In this study, the low efficiency limit of PLZST-based orthorhombic ceramics was overcome by precisely adjusting the Sn4+ content in the (Pb0.95Ca0.02La0.02)(Zr0.99‑x Sn x Ti0.01)O3 AFE ceramics. On one hand, the addition of Sn4+ disrupts the original long-range dipole and improves the rapid response of polarization reversal under the applied voltage. As a result, the difference in electric hysteresis under an electric field is reduced, leading to a significant improvement in energy storage efficiency. On the other hand, increasing the Sn4+ content suppresses the formation of oxygen vacancies, inhibiting grain growth and strengthening grain bonding. This results in ceramics with a high breakdown field strength. Ultimately, the resulting PLCZST ceramics reveal an expressively improved recoverable energy density of 10.2 J cm–3 together with a high energy efficiency of 91.4% under a high applied electric field of 560 kV cm–1. The present study demonstrates the tunability of performance in orthorhombic PLZST AFE ceramics, thereby introducing a ceramic material with exceptional energy storage capabilities for MLCC applications.
