Abstract

Abstract Dielectric ceramics with high energy storage performance are crucial for the development of advanced high‐power capacitors. However, achieving ultrahigh recoverable energy storage density and efficiency remains challenging, limiting the progress of leading‐edge energy storage applications. In this study, (Bi 1/2 Na 1/2 )TiO 3 (BNT) is selected as the matrix, and the effects of different A‐site elements on domain morphology, lattice polarization, and dielectric and ferroelectric properties are systematically investigated. Mg, La, Ca, and Sr are shown to enhance relaxation behavior by different magnitudes; hence, a high‐entropy strategy for designing local polymorphic distortions is proposed. Based on…
