Enhanced Energy Storage Performance in Na_0.5Bi_0.5TiO₃-Based Relaxor Ferroelectric Ceramics via Compositional Tailoring.

ABSTRACT: Owing to the high power density, excellent operational stability and fast charge/discharge rate, and environmental friendliness, the lead-free Na_0.5Bi_0.5TiO₃ (NBT)-based relaxor ferroelectrics exhibit great potential in pulsed power capacitors. Herein, novel lead-free (1-x)(0.7Na_0.5Bi_0.5TiO₃-0.3Sr_0.7Bi_0.2TiO₃)-xBi(Mg_0.5Zr_0.5)O₃ (NBT-SBT-xBMZ) relaxor ferroelectric ceramics were successfully fabricated using a solid-state reaction method and designed via compositional tailoring. The microstructure, dielectric properties, ferroelectric properties, and energy storage performance were investigated. The results indicate that appropriate Bi(Mg_0.5Zr_0.
