چکیده انگلیسی
High energy storage properties of 0.55Bi0.5Na0.5TiO3-0.45Ba0.85Ca0.15Ti0.9âxZr0.1SnxO3 (x = 0, 0.02, 0.05, 0.07) ceramics prepared by solid state route were first reported. The X-ray diffraction results reveal that all samples possess a pure perovskite structure phase. The investigation found that the moderate doping of Sn4+ in 0.55Bi0.5Na0.5TiO3-0.45Ba0.85Ca0.15Ti0.9Zr0.1O3 ceramic can decrease its phase transition temperature, and the slope of the P-E loops and the energy loss gradually decreased with the Sn4+ content increasing. A high breakdown strength of 13.02 kV/mm and the maximum discharge energy density of 1.21 J/cm3 were obtained for the sample with x = 0.05, of which the energy efficiency was as high as 72.08%. Thus, it was believed that our work could provide a significant guidance for designing the new systems for energy storage.
