摘要：
Energy density and fatigue resistance properties were investigated for lead-free Na0.46Bi0.46Ba0.05La0.02Zr0.03Ti0.97-xSnxO3 (for 0 <= x <= 0.15) ceramics, synthesized via solid-state reaction technique. Perovskite pseudo-cubic crystal structure was revealed for all ceramics using X-ray diffraction. Polarization and current density versus electric field were perceived and suggested the relaxor behavior with increasing composition. A high storage energy density similar to 1.58 J/cm(3), and conversion efficiency similar to 71.7% at similar to 110 kV/cm applied field was obtained for x = 0.03 composition at room temperature. Energy storage density was revealed similar to 1.53 J/cm(3), and efficiency similar to 88.6% at 110 degrees C with a 100 kV/cm applied field. In addition, ceramic x = 0.03 was fatigue-free from 1 to 10(5) cycles. Hence, the composition x = 0.03 might be applicable for high energy storage devices.
