In this work, we introduce a high entropy effect in designing relaxor ferroelectric (RFE)–antiferroelectric (AFE) crossover ceramic by incorporating relaxor-like oxide (Pb0.25Ba0.25Sr0.25Ca0.25)TiO3 with antiferroelectric NaNbO3. The results show that the ferroelectricity of system is enhanced increasing NaNbO3, and when new composition reaches highest configurational entropy, stable energy storage properties can be achieved. This enabled breakdown strength due to small grain size slim hysteresis loop efficiency entropy-stabilized short-range ordered polar nanoregions (PNRs). These findings showcase potential strategy for exploiting compositions high-performance electrostatic capacitors.

Dielectric capacitors exhibit great promise for use in advanced energy storage devices. Nevertheless, realizing a large density (Wrec) and high efficiency (η) remains an arduous challenge. In this work, multiscale manipulation strategy was employed by integrating polar-nanoregions (PNRs) regulation at the nanoscale grain-structure microscale to enhance performance of NaNbO3-based ceramics. The incorporation (Bi0.5Na0.5)0.7Sr0.3TiO3 (BNST) into (Na0.94La0.06)(Nb0.88Zr0.12)O3 (NLNZ) ceramics induces amount PNRs nanoscale, thereby giving rise η ultrafast discharge rate. addition, microscale, decreased grain size dense structure resistivity as well activation ceramics, thus leading breakdown electric field (Eb) consequently enhanced Wrec. At last, optimal (Wrec ∼ 9.3 J/cm3, 82.4% Eb 920 kV/cm) realized 0.80NLNZ-0.20BNST ceramic through manipulation. Furthermore, also demonstrates excellent stabilities under varying frequency (1-500 Hz), temperature (20-160 °C), cycling (1-106 cycles) outstanding charge/discharge performances (power PD 407 MW/cm3, current CD 1659 A/cm2, rate t0.9 13 ns). These results suggest that 0.80NLNT-0.20BNST exhibits significant application potential.

Abstract NaNbO 3 (NN)‐based materials have attracted widespread attention due to their advanced energy storage performance and eco‐friendliness. However, achieving high recoverable densities ( W rec ) efficiency η typically requires ultrahigh electric fields E > 300 kV/cm), which can limit practical use. In this work, we present a synergistic strategy that employs the ferroelectric material Bi 0.5 Na TiO (BNT) augment P max linear 0.2 Sr 0.7 (BST) optimize – loops. Furthermore, two‐step sintering process is implemented preserve values under lower field. As result, ternary (1− x )(0.90NN‐0.10BNT)‐ BST was successfully prepared, of 5.1 J/cm 85% in = 0.20 samples at low field 290 kV/cm. Moreover, showed good frequency stability (1–200 Hz) temperature (27°C–100°C). These results provide guidance for development ceramics with properties fields.
