A novel glass additive of 10Bi2O3‒5Li2O‒7.5Na2O‒7.5K2O‒21Nb2O5‒20.5SiO2‒10.5BaO‒11SrO‒4.5Al2O3‒0.5La2O3‒2TiO2 was melted to improve the energy‐storage properties of (Ba0.94Li0.02La0.04)(Mg0.04Ti0.96)O3 (BLLMT) ceramics (BLLMT‒x wt% G), which overcomes the paradox between polarization and voltage endurance. The dielectric constant and resistance of BLLMT ceramics are improved by glass modification, while the grain size decreases. Consequently, excellent breakdown strength of 565.9 kV/cm is obtained, and the difference between maximum polarization and remnant polarization reaches up to 22.14 µC/cm2. Weibull distribution and finite element simulation prove that grain boundary density, grain size, resistance, and bandgap width have significant effects on the breakdown strength. Finally, outstanding energy‐storage density of 4.82 J/cm3 is obtained at x = 2, accompanied with an excellent pulse discharged energy density of 3.42 J/cm3, current density of 1226.12 A/cm2, and power density of 337.19 MW/cm3. Excellent temperature stability is gained with the variation of the pulse discharged energy density less than 10% at 20°C‒140°C. The outstanding pulse energy‐storage parameters are related to phase structure, small grain size, high grain boundary density, formation of liquid phase, increased ceramic resistance, and destroyed long‐range ordered ferroelectrics. This work provides a novel idea for fabricating glass to obtain excellent energy‐storage performance and promotes practical application of BaTiO3 ceramics.

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.

“…In addition, PbHf 0.925 Sn 0.075 O 3 antiferroelectric ceramics had a high energy storage density of 10.1 J/cm 3 . However, due to the irreversible damage to the environment and human health caused by lead-containing ceramics, as well as the inconsistency with the concept of green development in the new era, researchers have been actively exploring alternative lead-free dielectric ceramics . NBT-based ceramics are typical lead-free ferroelectric materials with large polarization and high Curie point, which have potential high energy storage performance and high-temperature applications. − However, the large residual polarization P r and coercive field E c limit the release of stored energy in pure NBT.…”

(Na0.5Bi0.5)0.75Sr0.25TiO3–x Sm2O3 ceramics (denoted as NBSTS x ) were obtained by the solid-state reaction method, and their crystal structure and morphological characteristics were characterized by X-ray diffractometer mapping (XRD) and scanning electron microscopy (SEM). The NBSTS x ceramics, when doped with a concentration of x = 0.03, demonstrated outstanding performance in terms of maximum recoverable energy storage density (W rec ∼ 3.35 J/cm3) and energy storage efficiency (η ∼ 84.8%). This ceramic exhibited the highest potential at an electric field strength of 210 kV/cm. Additionally, the thermal stability of NBSTS0.03 ceramic remained constant within the temperature range of 30–90 °C, while their frequency stability covered the range of 10–1000 Hz. By analyzing the dielectric spectra of the material, we investigated the variation of the relative permittivity (εr ) and the dielectric loss angle tangent (tan δ), and we probed the relaxation behavior by means of a modified Curie–Weiss law. The NBSTS x ceramic with a density of x = 0.03 exhibited a fast charge/discharge rate of 128 ns and a discharge energy density of 1.06 J/cm3. From the impedance spectra, the relaxation phenomena observed in the system could potentially be attributed to the migration of oxygen vacancies.
