Abstract

Dielectric materials with high energy storage density ([Formula: see text]) and efficiency ([Formula: see text]) are expected for energy storage capacitors. In this work, [Formula: see text]001[Formula: see text]-textured Na[Formula: see text]Bi[Formula: see text]NbO3 (NBN) ceramics were prepared by a templated grain growth technique. The effects of microstructure and orientation degree on dielectric properties, polarization and energy storage performance were investigated. The textured ceramic with an optimized orientation degree (70%) showed a high [Formula: see text] of 2.4 J/cm3 and [Formula: see text] of 85.6%. The excellent energy storage properties of textured ceramic originate from the co-effect of interfacial polarization and clamping effect. The results indicate that texture development is a potential candidate to optimize the energy storage properties of functional ceramics.

< 001 >织构nanbo3基陶瓷的制备及其储能性能

储能电容器需要具有较高的储能密度([公式:见文])和效率([公式:见文])的介电材料。本研究采用模板化晶粒生长技术制备了[公式:见文]001[公式:见文]-织构Na[公式:见文]Bi[公式:见文]NbO3 (NBN)陶瓷。研究了材料的微观结构和取向程度对介电性能、极化性能和储能性能的影响。取向度优化后(70%)的织构陶瓷具有较高的[公式:见文]2.4 J/cm3和[公式:见文]85.6%。织构陶瓷优异的储能性能源于界面极化和夹紧效应的共同作用。结果表明，织构发育是优化功能陶瓷储能性能的潜在选择。

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).
