Abstract
Bi0.5Na0.5TiO3 ceramic is a promising dielectric energy storage material due to its high spontaneous polarization (> 40 μC/cm2). Although many studies have been carried out to enhance the energy storage performance of Bi0.5Na0.5TiO3 ceramic, achieving better energy storage performance is still a considerable challenge. Herein, Bi0.5Na0.5TiO3-BiYbO3-SrTiO3 (BNT-BY-STO) relaxor ferroelectric ceramics were constructed, and <111>-oriented (1-x)(0.99BNT-0.01BY)-xSTO ceramics were successfully fabricated by a templated grain growth method. The moderate energy storage performance (the reversible energy storage density of 3.26 J/cm3 and energy storage efficiency of 76.3 % under 290 kV/cm) can be achieved in <111>-oriented 0.8(0.99BNT-0.01BY)-0.2STO ceramics. The enhanced energy storage performance of textured BNT-BY-STO ceramics could be mainly attributed to the grain refinement of STO, and the improved breakdown strength and relaxation behavior caused by orientation engineering. These findings demonstrate that the co-doping of BY and STO and orientation engineering are effective strategies for improving the energy storage performance of BNT ceramic.
期刊介绍:
Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
