Abstract
- (1 − x)Sr<subscript>0.7</subscript>Bi<subscript>0.2</subscript>TiO<subscript>3</subscript>-xBi(Mg<subscript>0.5</subscript>Ce<subscript>0.5</subscript>)O<subscript>3</subscript> (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/cm<superscript>3</superscript>, recoverable energy density of ~ 1.67 J/cm<superscript>3</superscript>, 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/C<subscript>25°C</subscript> in the range of − 55 to 135 °C. The above characteristics indicate that this material is a suitable candidate for power-pulsed capacitor applications. [ABSTRACT FROM AUTHOR]
