High Energy Storage Density and Impedance Response of PLZT2/95/5 Antiferroelectric Ceramics

“…The small anomalous peak was interpreted by the phase transition AFE to FE [22,23] ( T o = 155 °C), whereas the maximum anomalous peak was linked with the transformation of FE to PE phase ( T C = 225 °C) at the higher temperature. The samples exhibited FE and AFE coexistence state when T exceeds T o and PE state when T exceeds T C [3]. The dielectric data in Figure 2a were maximum for a temperature of about 225 °C, which was in line with the FE curie temperature ( T C = 225 °C) obtained in PLZT2/95/5 bulk materials [24,25] or about 222 °C in PLZT2/95/5 thick films [26].…”

“…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].…”

Multifunctional antiferroelectric MLCC with high‐energy‐storage properties and large field‐induced strain

“…It is well‐known that the low electric breakdown field for the bulk ceramics often leads to inferior final properties, such as small energy‐storage density and low cooling coefficient. Although much high breakdown field could be realized in the films, the overall performance including stored energy and strains are unacceptable, due to the limitation of their small volume . Comparatively, MLCC can successfully overcome the problems in bulk ceramics and thin films.…”

Enhanced energy storage density by inducing defect dipoles in lead free relaxor ferroelectric BaTiO3-based ceramics

“…So, there are two possible routes to improve the energy-storage density of AFE and FE ceramics for energy storage applications: One is to enhance the BDS for high E and another is to increase the limit of integration by enlarging the difference between the P max and P r . For the first route, it was found that AFE ceramic ( [17][18][19][20][21] It indicated that partial occupancy of Bi 3þ at the A site of the perovskite compound could effectively improve the energy storage properties. As a promising candidate system, relaxor ferroelectrics BaTiO 3 (BT)-based ceramics play a key role in the area of energy density capacitors because of their low P max , high P r , and low loss.…”
