Abstract

Abstract: Energy density and fatigue resistance properties were investigated for lead-free Na0.46 Bi0.46 Ba0.05 La0.02 Zr0.03 Ti0.97- x Sn x O3 (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 ~1.58 J/cm 3, and conversion efficiency ~71.7% at ~110 kV/cm applied field was obtained for x = 0.03 composition at room temperature. Energy storage density was revealed ~1.53 J/cm 3, and efficiency ~88.6% at 110 °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.
