摘要：
(1 − x)Sr0.7Bi0.2TiO3-xBi(Mg0.5Ce0.5)O3 (x = 0.02, 0.04, 0.06, and 0.1) ceramics were prepared through the solid-state reaction method. Structural, microstructural, dielectric, and energy storage characteristics were thoroughly examined. A dense microstructure with a single perovskite phase was obtained for x ≤ 0.06. A high energy storage density of ~ 1.86 J/cm3, recoverable energy density of ~ 1.67 J/cm3, and a high efficiency of ~ 90% at a breakdown electric field strength of 240 kV/cm were achieved for x = 0.06. Further, this composition also shows a ΔC/C25°C in the range of − 55 to 135 °C. The above characteristics indicate that this material is a suitable candidate for power-pulsed capacitor applications.
