Pursuing advanced dielectric ceramics with remarkable energy storage density at low electric field (E) is pivotal to achieving miniaturization in integrated circuits. In order to simultaneously obtain high recoverable energy storage density (Wrec), remarkable energy storage efficiency (η), and enhanced stability under...
Dielectric capacitors are essential components in modern electronic devices, but their limited energy storage performance has become one of the core obstacles to their cutting-edge applications. Herein, by constructing nanodomains and improving electric field endurance, Bi0.5Na0.5TiO3–SrTiO3–Sr(Sc0.5Ta0.5)O3 relaxor fe...
The influence of Ta5+ substitution on lead-free (Bi0.465Na0.465Ba0.07)TaxTi(1–x)O3 (BNBT–xTa, x = 0.0 to 0.03) ceramics was investigated. The samples were prepared using a conventional solid-state route, resulting in a phase-pure perovskite structure with pseudocubic characteristics for all compositions. With increasin...
As a lead-free material located at the morphotropic phase boundary, Ba0.85Ca0.15Zr0.1Ti0.9O3 possesses an exceptionally high polarization potential, making it an attractive candidate matrix for high-performance energy storage ceramics. However, its practical application is largely limited by a low breakdown electric fi...
