Abstract

Lead-free ceramics ((Bi_0.5Na_0.5)_0.7(Sr_0.7Bi_0.2)_0.3)_1-xSm_x)TiO₃ (x = 0.0, 0.005, 0.01, 0.02, 0.03) with a novel phase boundary structure were successfully synthesized. All samples sintered well and shown pure perovskite structure. The doping of Sm³⁺ inhibits the grain growth and enhanced the relaxor properties. Besides, the activity of polar nanoregion (PNRs) is improved. Ferroelectric analysis showed that proper Sm³⁺ doping played a pegging role on the saturated polarized P_m, leading to a higher and slimmer P-E loop. As a result, a large energy storage density (~ 1.25 J/cm³) with high energy efficiency (~ 73%) were achieved at x = 0.005 under an electric field of 90 kV/cm. Further, the sample was found to have good temperature stability between room temperature and 110 °C. This study shows that ceramic material has great potential for the application of high-temperature stability energy storage capacitors.
