Ceramic‐based dielectric capacitor are highly suitable for pulsed power applications due to their high power density and excellent reliability. However, the ultrahigh applied electric field limit their applications in integrated electronic devices. In this work, (1−x){0.96(Bi0.5Na0.5)(Ti0.995Mn0.005)O3‐0.04BiAlO3}‐xNaNbO3 (BNT‐BA‐xNN, x = 0, 0.04, 0.08, 0.12, and 0.16) ternary ceramics were designed to achieve excellent energy storage properties. It was found that the introduction of NaNbO3 (NN) effectively increase the difference (ΔP) between Pmax and Pr, resulting in an obvious enhancement of the energy storage properties. High recoverable energy storage density, responsivity, and power density, that is, Wrec = 2.01 J/cm3, ξ = Wrec/E = 130.69 J/(kV⋅m2), and PD = 25.59 MW/cm3, accompanied with superior temperature stability were realized at x = 0.14 composition. In addition, the thermal stable dielectric properties of the sample can be prominently improved with increasing NN content. The temperature coefficient of capacitance (TCC) of x = 0.16 composition is lower than 15% over the temperature range from 49°C to 340°C, with a high dielectric permittivity of 1647 and a low dielectric loss (0.0107) at 150°C. All these features show that the BNT‐BA‐xNN ceramics are promising materials for energy storage application.

The compounds xBi(Mg2/3Nb1/3)O3‐(1 − x)(Ba0.8Sr0.2)TiO3 (xBMN‐(1 − x)BST, 0.08 ≤ x ≤ 0.14) are prepared via the traditional solid‐state reaction method and the ceramics are well densified in the sintering temperature range of 1280–1330 °C. X‐ray diffraction analysis shows that all the ceramics crystallize into perovskite structure. Proper amounts of BMN additions can effectively reduce grain sizes of the xBMN‐(1 − x)BST ceramics, resulting in more uniform microstructures. Accordingly, breakdown strength Eb is improved and a maximum value 250 kV cm−1 is obtained in ceramic with x = 0.10. Meanwhile, recoverable energy storage density Wrec of the 0.1BMN‐0.9BST ceramics reaches 2.03 J cm−3, and energy storage efficiency (η) is 96.8%. When the operating temperature increases to 150 °C, the Wrec and η values are about 1.02 J cm−3 under 150 kV cm−1 and 89.8%, respectively.

Although ceramic dielectric materials have been extensively explored owing to their numerous advantages, there are still obstacles in the collaborative enhancement of recoverable energy density (W rec ) and efficiency (η). In this work, a combinatorial optimization strategy is proposed to optimize energy storage properties of (K, Na)NbO 3 -based ceramics, that is, drive a specific temperature region between the temperature of maximum dielectric constant and the Burns temperature to room temperature under the guidance of phase field simulation to induce the polar nanoregions, then further improve the breakdown strength by repeated rolling process. As a result, an ultrahigh W rec of 6.7 J cm −3 and a high η of 92% at 600 kV cm −1 are achieved simultaneously in the 0.85K 0.5 Na 0.5 NbO 3 -0.15Bi(Zn 2/3 Ta 1/3 )O 3 ceramic prepared by repeated rolling process, together with excellent temperature stability under 400 kV cm −1 over a temperature range of 25 to 150 °C, outperforming all reported (K, Na)NbO 3based energy storage ceramics. This approach should also be generalizable for designing high-performance dielectrics for electrical energy storage applications.
