Abstract The development of ceramics with superior energy storage performance and transparency holds the potential to broaden their applications in various fields, including optoelectronics, devices, transparent displays. However, designing a material that can achieve high density under low electric fields remains challenge. In this work, (1− x )Bi 0.5 Na TiO 3 − BaZr 0.3 Ti 0.7 O :0.6mol%Er 3+ (abbreviated as )BNT− BZT:0.6%Er ) ferroelectric translucent were prepared by conventional solid‐state reaction method. properties are systematically investigated modulating coupling between coexisting phase structures polar nano regions. Especially, 0.9BNT–0.1BZT:0.6%Er ceramic exhibits an ultra‐high maximum polarization ( P max = 66.3 µC/cm 2 ), large recoverable W rec 2.95 J/cm total 5.75 efficiency η 51.3%) 190 kV/cm. sample also excellent thermal stability (30‐150°C) transmittance (∼28%). This work could facilitate advancement systems more efficient cost‐effective, provide opportunities for design manufacture novel devices.

Relaxor ferroelectrics based on sodium bismuth titanate (Bi0.5Na0.5TiO3, BNT) have attracted more interest recently as potential ecologically acceptable materials for pulse power technology because of their excellent full-energy storage capabilities. This paper formed (1 − x){0.97[0.98(BNT-ST)-0.02CN]-0.03AlN}-xNN ceramics through a traditional solid-state reaction process. It was noted that the incorporation NaNbO3 enhances property energy by elevating breakdown strength and causing creation an ergodic relaxation state. The effective density (Wrec) efficiency (η) are 1.09 J/cm3 85%, respectively. field Eb reached 155 kV/cm at x = 40%. These temperatures frequency stabilities from 0.5 to 50 Hz 20 60 °C.

Superior Energy-Storage Performances under a Moderate Electric Field Achieved in Antiferroelectric-like Na_0.5Bi_0.5TiO₃-Based Relaxor Ferroelectric Ceramics by a Synergistic Optimization Strategy

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 28, 2024

The progress of power systems and electronic devices promotes the development lead-free dielectric energy-storage material. Particularly, Na0.5Bi0.5TiO3-based ferroelectric ceramics featuring large spontaneous polarization as well wide adjustability stability are highly recognized promising candidates. However, their remanent (Pr) low electric breakdown strength (Eb) result in unsatisfactory recoverable energy density (Wrec) and/or conversion efficiency (η), severely restricting applications. Herein, an effective synergistic optimization strategy has been proposed to gain superior performances. Interestingly, antiferroelectric-like (AFE-like) (1 – x)(Na0.3Bi0.38Sr0.28TiO3)-xBi(Mg0.5Zr0.5)O3 (x = 0.00, 0.05, 0.10, 0.15, 0.20) relaxor (RFE) were constructed via phase structure, polar defect dipole modulations. With Bi(Mg0.5Zr0.5)O3 increasing, slim pinched polarization–electric field hysteresis (P–E) loops become remarkably similar double-like P–E characterized by AFEs. Meanwhile, strengthened Eb delayed saturation also realized due enlarged band gap, refined grain size, reduced free barrier. Consequently, performances achieved this work. Noticeably, a Wrec 5.00 J/cm3 high η 90.09% 0.85(Na0.3Bi0.38Sr0.28TiO3)-0.15Bi(Mg0.5Zr0.5)O3 RFE at moderate 340 kV/cm. Additionally, excellent charge–discharge reliabilities frequency (1–500 Hz), temperature (20–140 °C), fatigue cycle (1–50,000) confirmed. These satisfactory results not only indicate prospects but verify effectiveness
