Abstract Dielectric capacitors, which can achieve tremendous power density and ultrafast charge/discharge speed, are crucial components for high equipment. Yet, the synchronous achievement in recoverable energy ( W rec ) efficiency η is a long‐term difficulty dielectric ceramics. Herein, (0.85 − x )NaNbO 3 –0.15BaTiO – Bi(Mg 1/3 Ta 2/3 )O (NN–BT– BMT) relaxor ferroelectric ceramics were proposed studied. The doping of BMT was conducive to promoting microstructure bandgap improving relaxation properties NN–BT Finally, sample = 0.10 presented 5.9 J/cm 90% simultaneously. In addition, also exhibited superb performances with large P D 137 MW/cm fast speed t 0.9 39 ns). above results reveal that NaNbO ‐based could serve as potential alternatives advanced capacitors.

The development of lead-free relaxor ferroelectric ceramics with high energy storage density has emerged as a critical area, driven by the increasing demand for advanced capacitors and high-power devices. Conventional approaches to enhance energy-storage performance in dielectric typically rely on achieving ultrahigh breakdown field strength (Eb) or employing complex multicomponent composite strategies. However, requirement electric fields hinders miniaturization integration Furthermore, despite extensive research classic BaTiO3-based system, recoverable densities exceeding 6 J/cm3 remain exceedingly rare, especially under moderate (300 kV/cm < E 500 kV/cm). In this paper, based relationship among permittivity (εr) (Wcal=12ε0εrE2), we constructed superparaelectric state near room temperature improved εr introducing centrosymmetric BiScO3 into matrix (Ba0.65Sr0.3Ca0.05Sn0.02Ti0.08O3). Ultimately, strategy enables realization an 6.95 efficiency 86.17% (500 These findings provide practical innovative pathway developing high-performance capacitors, advancing potential next-generation technologies.

Bismuth sodium titanate (Bi0.5Na0.5TiO3)-based relaxor ferroelectric ceramics have received ever-increasing interest for their potential application in dielectric capacitors owing to sterling energy storage capability. Herein, the perovskite end-member Ba(Fe0.5Nb0.5)O3 (BFN) was incorporated into 0.7Bi0.5Na0.5TiO3-0.3SrTiO3 (0.7BNT-0.3ST) improve characteristics and refine grain, leading slim polarization–electric field (P–E) hysteresis loops enhanced electric breakdown strength. Particularly, 0.85(0.7BNT-0.3ST)-0.15BFN achieved a high recoverable density of 5.7 J/cm3 efficiency 86.4% under moderate 390 kV/cm. Additionally, remarkable stability frequency, cycling, temperature excellent charge/discharge behavior were at same time. The above findings reveal that BFN-modified BNT-ST display greatly improved comprehensive properties, making them promising candidates electrostatic storage.
