As one of the important electronic components, the dielectric capacitors for energy storage applications have been extensively studied in recent years. Among various dielectric materials, the perovskite oxide Bi0.5Na0.5TiO3‐based ceramics have become promising candidates due to their high polarization, dielectric tunability, environment‐friendly composition, and so forth. Herein, the relaxor ferroelectric ceramics of Bi0.5Na0.5TiO3–SrTiO3–Bi(Mg0.5Zr0.5)O3 were prepared via solid‐state reaction method. The sample with optimal composition not only retains the high polarization by introducing Bi3+ ions, but also achieves the reduced remanent polarization by enhancing relaxor behavior and the promoted electric breakdown strength by the grain size refinement. Accordingly, a high recoverable energy density of 8.3 J/cm3 under 450 kV/cm and the superb charge/discharge properties (current density CD = 1200 A/cm2, power density PD = 150 MW/cm3, charge/discharge time t0.9 = 0.15 µs) are achieved, revealing great prospect in energy storage applications.

“…With the incorporation of SANT, the value of E g raises from 3.09 eV at x = 0 to 3.21 eV at x = 0.16, which indicates that electrons are difficult to jump from the valence band to the conduction band 28,34,43 . In addition, the large bandgap width is beneficial to improve insulation characteristics and intrinsic resistance, which leads to the enhancement of E b 39,44 . However, the value of E g slightly suppresses from 3.21 eV to 3.19 eV, which is related to donor doping and abnormal grain growth, 28 resulting in a decrease in E b for x = 0.20.…”

Eco‐friendly ceramic capacitors gradually become an important section of pulsed power devices. However, the synchronous realization of ultra‐high energy storage density (Wrec > 6 J/cm3) and efficiency (η > 90%) is difficult. Thus, a novel multiscale amelioration strategy in Na0.5Bi0.5TiO3‐based ceramics is proposed to achieve ultra‐high energy storage density and efficiency. The multiscale amelioration strategy for (Na0.5Bi0.47La0.03)0.94Ba0.06TiO3 (NBLBT) ceramic focuses on grain size, bandgap width, and dielectric relaxor behavior, which can be regulated by introducing Sr(Al0.5Nb0.25Ta0.25)O3 (SANT). On the one hand, the refined grain size and increased bandgap width are conducive to improving the breakdown strength. On the other hand, the optimized dielectric relaxation behavior is beneficial to suppress the remanent polarization. Accordingly, an ultrahigh Wrec = 6.89 J/cm3 and η = 90.1% are simultaneously achieved in 0.84NBLBT‐ 0.16SANT ceramic. In addition, the sample synchronously possesses excellent thermal and frequency stability (a variation within 5% in Wrec and η), transient discharge rate of t0.9 ∼ 78.8 ns and a high‐power density of PD ∼ 114.5 MW/cm3. This study provides an effective strategy to further develop pulsed power devices.

AgNbO 3 (AN)-based lead-free antiferroelectric (AFE) ceramic materials have garnered significant research attention due to their distinctive AFE structures and potential applications in pulse dielectric capacitor devices. However, their inferior energy storage performance (ESP) has hindered further advancements in practical use. To address this challenge, we introduce a synergistic optimization strategy aimed at enhancing the ESP of AN-based ceramics. Initially, we incorporate Bi 3+ ions into the A-site and Ta 5+ ions into the B-site of the ABO 3 -structured AN crystal lattice. This deliberate modification leverages the smaller radius of Bi 3+ ions compared to Ag + ions, effectively reducing the tolerance factor and enhancing oxygen octahedral torsion, thereby stabilizing the AFE phase. Additionally, the hybridization of Bi 3+ ions' 6s orbitals with O 2− ions' 2p orbitals amplifies polarization. By finely adjusting the Nb 5+ /Ta 5+ ion concentration ratio to control the AFE and paraelectric phase content, we regulate the electric field-induced polarization and its response trajectory, ultimately improving the ESP of the materials while minimizing hysteresis. Comprehensive characterization of (Ag 0.955 Bi 0.015 )(Nb 1−x Ta x )O 3 ceramics was performed through X-ray diffraction refinement, temperaturedependent dielectric properties, and transmission electron microscopy, revealing the intricate interplay between atoms, structure, and properties. Our investigation culminates in demonstrating an ultrahigh recoverable energy storage density of 7.06 J/cm 3 and an energy storage efficiency of 75% at 470 kV/cm in (Ag 0.955 Bi 0.015 )(Nb 0.75 Ta 0.25 )O 3 ceramics, accompanied by exceptional temperature stability from room temperature to 140 °C. This systematic research lays the groundwork for fabricating AN-based ceramic capacitors with enhanced ESP through the synergistic optimization strategy.
