Abstract [en]
(1-x)(0.72Bi0.5Na0.5TiO3-0.28SrTiO3)-xBiAlO3 (BNT-ST-xBA) lead-free ceramics were prepared through solid-state sintering methods. The structural, dielectric and energy storage properties of the ceramics were studied in this work. A large energy storage density of BNT-ST-0.01BA ceramics exceeding 1.746 J/cm3 has been obtained. The ceramics exhibit a good thermal stability at the temperature ranging from 20 °C to 120 °C. In addition, energy storage properties are relatively stable after completing 10000 electrical cycles, which shows promising potential for energy storage devices at a high temperature region.
