Abstract
- Because of high voltage resistance and high-power density, traditional ceramic dielectrics have found extensive use in electronic and pulsed power systems. Nevertheless, their subpar energy storage capabilities pose a challenge in meeting the demands of integrated and lightweight power electronic devices. This paper employs compositional design to incorporate a Bi(Zn<subscript>0.5</subscript>Hf<subscript>0.5</subscript>)O<subscript>3</subscript> (BZH) relaxation component, aiming to enhance the electrical breakdown strength or effective dielectric constant, ultimately increasing the energy storage density. The 0.90(Ba<subscript>0.8</subscript>Sr<subscript>0.2</subscript>)TiO<subscript>3</subscript>–0.10Bi(Zn<subscript>1/2</subscript>Hf<subscript>1/2</subscript>)O<subscript>3</subscript> ceramics processed by the conventional solid-phase reaction method demonstrate a significant recoverable energy density of 4.20 J cm<superscript>−3</superscript>, an exceptional energy storage efficiency of 95.5%, with a 450 kV cm<superscript>−1</superscript> high breakdown strength and impressive charge/discharge performance. This investigation presents a novel framework for enhancing energy storage performance in other material systems. [ABSTRACT FROM AUTHOR]
