Optimization of energy storage properties in (1 − x)Na0.5Bi0.5TiO3-xSr0.7La0.2TiO3-relaxed ferroelectric ceramics
Ferroelectric materials are considered to be the most competitive energy storage materials for applications in pulsed power electronics due to excellent charge–discharge properties. However, the low energy storage density is the primary problem limiting their practical application. In this study, (1[Formula: see text])Na[Formula: see text]Bi[Formula: see text]TiO3–[Formula: see text]Sr[Formula: see text]La[Formula: see text]TiO3[(1[Formula: see text])NBT–[Formula: see text]SLT] ferroelectric ceramics are found to exhibit excellent energy storage performances through a synergistic strategy. As the SLT concentration increases, the relaxation characteristic increases significantly and the breakdown strength increases dramatically from 150 kV/cm to 220 kV/cm. The recoverable energy storage density of the 0.55NBT–0.45SLT ceramic is 2.86 J/cm3 with an energy storage efficiency of 88% under an electric field of 220 kV/cm. Furthermore, the ceramic with [Formula: see text] = 0.45 mol exhibited excellent energy storage stability in the ranges of 20–180[Formula: see text]C (temperature) and 1–125 Hz (frequency). These excellent properties demonstrate the potential of (1[Formula: see text])NBT–[Formula: see text] SLT ceramics when used as dielectric capacitors in pulsed power systems.
期刊介绍:
The Journal of Advanced Dielectrics is an international peer-reviewed journal for original contributions on the understanding and applications of dielectrics in modern electronic devices and systems. The journal seeks to provide an interdisciplinary forum for the rapid communication of novel research of high quality in, but not limited to, the following topics: Fundamentals of dielectrics (ab initio or first-principles calculations, density functional theory, phenomenological approaches). Polarization and related phenomena (spontaneous polarization, domain structure, polarization reversal). Dielectric relaxation (universal relaxation law, relaxor ferroelectrics, giant permittivity, flexoelectric effect). Ferroelectric materials and devices (single crystals and ceramics). Thin/thick films and devices (ferroelectric memory devices, capacitors). Piezoelectric materials and applications (lead-based piezo-ceramics and crystals, lead-free piezoelectrics). Pyroelectric materials and devices Multiferroics (single phase multiferroics, composite ferromagnetic ferroelectric materials). Electrooptic and photonic materials. Energy harvesting and storage materials (polymer, composite, super-capacitor). Phase transitions and structural characterizations. Microwave and milimeterwave dielectrics. Nanostructure, size effects and characterizations. Engineering dielectrics for high voltage applications (insulation, electrical breakdown). Modeling (microstructure evolution and microstructure-property relationships, multiscale modeling of dielectrics).
