High energy storage capacity, heterogeneous domain structure and stabilization of intermediate phase in PbZrO₃-based antiferroelectric single crystals

Abstract

Lead zirconate PbZrO3 (PZ)-based antiferroelectric (AFE) materials have received tremendous attention due to their potential applications in high density energy storage capacitors. However, PZ suffers from an ultrahigh critical electric...

Ferroelectric anomaly of perovskite layer structured Pb2+‐doped Sr2Nb2O7 ceramics

“…The most important AFEs are the ones with ABO 3 perovskite structure, such as PbZrO 3 (PZ) and PZ-based Pb(Zr,Ti)O 3 , (Pb,La)(Zr,Sn,Ti)O 3 and Pb(Zr,Sn,Ti,Nb)O 3 , BiFeO 3 , AgNbO 3 , NaNbO 3 , and (Na 0.5 Bi 0.5 )TiO 3 compounds. [7][8][9][10][11][12][13] These AFE materials are strongly dependent on the FE-AFE phase transition, which are determined by the compositional design and external electric field. Recently, Ba 4 Sm 2 Ti 4 Nb 6 O 30 and Ba 4 Eu 2 Ti 4 Nb 6 O 30 with tungsten bronze structure have been reported antiferroelectricity with a double P-E hysteresis loop caused by the field-induced transition from nonpolar incommensurate modulation to polar commensurate modulation.…”

“…After applying sufficiently external electric field, AFE materials show a distinct double polarization–electric field ( P – E ) hysteresis loop. The most important AFEs are the ones with ABO 3 perovskite structure, such as PbZrO 3 (PZ) and PZ‐based Pb(Zr,Ti)O 3 , (Pb,La)(Zr,Sn,Ti)O 3 and Pb(Zr,Sn,Ti,Nb)O 3 , BiFeO 3 , AgNbO 3 , NaNbO 3 , and (Na 0.5 Bi 0.5 )TiO 3 compounds 7–13 . These AFE materials are strongly dependent on the FE–AFE phase transition, which are determined by the compositional design and external electric field.…”

Synergistic design of a new PbHfO3-based antiferroelectric solid solution with high energy storage and large strain performances under low electric fields

“…5 However, the E cr for many prototypical AFE materials [such as (PbZrO 3 , PZ) and (PbHfO 3 , PHf)] is much higher than their breakdown field ( E b ) at room temperature (RT). 6,7 Therefore, this study aims to understand the phase transition mechanism and to develop an effective strategy to realize the AFE-FE phase transition under low electric fields in AFE materials.…”

Enhancement of Energy Storage Density and Efficiency of PbHfO3 Doped with La Antiferroelectric Thin Films

“…In industrial applications, energy storage systems must possess the following properties: excellent recoverable energy storage density ( W rec ), satisfactory fatigue resistance, and high-temperature resistance. , Compared to other types of capacitors, dielectric capacitors typically exhibit higher energy storage efficiency (η) and more stable energy storage characteristics. W rec and η of dielectric capacitors can be expressed as follows , W normalr normale normalc = prefix∫ P normalr P normalm normala normalx E d P W = W rec + W loss η = W rec W × 100 % where P max and P r are the maximum and remnant polarization, respectively, E is the electric field, and W loss is the energy loss density. Antiferroelectric materials have large P max and low P r because the adjacent crystals in their structures exhibit polarization in reversed and parallel directions, forming a double hysteresis loop.…”
