چکیده انگلیسی
(1-x)NBT-xBSN (0.1â¯â¤â¯xâ¯â¤â¯0.35) ceramics were prepared by solid state methods and their energy storage properties and high-temperature capacitor applications were systematically investigated. All samples showed a perovskite structure and the structure transformed to lower symmetry orthorhombic phase (xâ¯â¥â¯0.1) from rhombohedral phase (xâ¯<â¯0.1) to with the addition of BSN. The more addition content of BSN significantly decreases phase transition temperature Tm of NBT ceramics. The xâ¯=â¯0.25 sample exhibits a stable relative permittivity of 1605â¯Â±â¯15% in a broad temperature range of 38â¯Â°C to 319â¯Â°C. With increasing BSN concentration, the slope of the P-E loops and the energy loss gradually decreases. When xâ¯=â¯0.25, a high breakdown strength of 190â¯kV/cm and the maximum discharge energy density of 1.91â¯J/cm3 were obtained, of which the energy efficiency was as high as 86.4%. Thus, it was believed that our work could provide a significant guidance for designing the new system for energy storage.
