“…Electrical capacitors display an extremely high powder density but their energy storage density needs further improvement [1,2,3,4]. Antiferroelectric (AFE) ceramics are promising candidates for dielectrics in high energy density electrical capacitors due to the reversible electric field-induced AFE to ferroelectric (FE) phase transition [5].…”

(Pb 0.97 La 0.02 )(Zr 0.95 Ti 0.05 )O 3 (PLZT2/95/5) ceramics were successfully prepared via a solid-state reaction route. The dielectric properties were investigated in the temperature region of 26-650 • C. The dielectric diffuse anomaly in the dielectric relaxation was found in the high temperature region of 600-650 • C with increasing the measuring frequency, which was related to the dynamic thermal process of ionized oxygen vacancies generated in the high temperature. Two phase transition points were detected during heating, which were found to coexist from

“…However, W re at 8 kV/mm shows only tiny fluctuation from 1.05 J/cm 3 at RT to 1.01 J/cm 3 at 100°C, with variation of 3.8%. The change rate of W re at 8 kV/mm is less than 0.5% per 10°C, which is much better than previous reports . More importantly, the results suggest that the T ‐dependent W re relationship of AFEs can be tuned through optimizing the working E .…”

“…It is well known that AFEs possess higher W re under higher E , as shown in Figure A. Therefore, a large number of studies were focused on improving W re through choosing largest possible E or enhancing the dielectric breakdown strength . However, this work proves that higher working E will probably result in a temperature‐sensitive W re , which is not suitable for practical application.…”

“…As energy storage devices are always needed to operate in different temperature environments, excellent thermal stability of W re is also a must to ensure their reliable operation. Therefore, researchers pay more and more attention on the W re –temperature relationship and several kinds of AFE films and ceramics with weak temperature‐dependent W re have been reported recently .

The electrical hysteresis behaviors and energy storage performance of Pb0.97La0.02(Zr0.58Sn0.335Ti0.085)O3 antiferroelectric (AFE) ceramics were studied under the combined effects of electric field and temperature. It was observed that the temperature dependence of recoverable energy density (Wre) of AFE ceramics depends critically on the applied electric field. While Wre at lower electric fields (<8 kV/mm) shows increasing tendency with increasing temperature from 20°C to 100°C, Wre at higher electric fields (>8 kV/mm) demonstrates decreasing dependence. There exists an appropriate electric field (8 kV/mm) under which the AFE ceramics exhibit nearly temperature‐independent Wre (the variation is less than 0.5% per 10°C). The underlying physical principles were also discussed in this study. These results indicate that the temperature dependence of Wre of AFE materials can be tuned through selecting appropriate electric fields and provide an avenue to obtain thermal stable energy storage capacitors, which should be of great interest to modern energy storage community.

The phase transition and dielectric properties of Pb0.988(Hf0.945SnxTi0.03‐xNb0.025)O3 ceramics (0 ≤ x ≤ 0.03, correspondingly abbreviated as H1, H2, H3, and H4) at the morphotropic phase boundary were systematically investigated. X‐ray diffraction results and P‐E hysteresis loops show that the dominate orthorhombic antiferroelectric phase and a small amount of the tetragonal FE phase coexist in Pb0.988(Hf0.945SnxTi0.03‐xNb0.025)O3 ceramics. As the Sn content increases, the antiferroelectricity is significantly enhanced, accompanied with an increased Curie temperature and sharply reduced peak dielectric constant. H1 and H2 experience an irreversible field‐induced AFE‐FE phase transition at the ambient temperature, and the transition from a metastable FE phase to the original AFE phase is observed in H2 when heated to 60°C. H3 and H4 experience an invertible AFE‐FE phase transition, along with an enhanced forward phase switching field EF. Moreover a decreased backward phase switching field EA for H4 is detected as the electric field increases due to the AFE/FE coexistence. These results reveal the unique phase transition characteristics of AFE materials near the phase boundary, which is helpful for better understanding of AFE/FE materials.
