Abstract

Novel lead-free [(Bi0.5Na0.5)(0.94)Ba-0.06](0.97)La0.03Ti1-x(Al0.5Nb0.5)(x)O-3 ceramics (BNBLT-xAN) were prepared by the conventional solid state sintering method. The dielectric, ferroelectric, ac impedance and energy-storage performance were systematically investigated. Temperature dependent permittivity curves showed that relaxation properties of sintered ceramics gradually diminished with the increase of AN. The introduction of AN gave rise to a slimmer polarization hysteresis loop (P-E) and an enhanced dielectric breakdown strength (DBS). Therefore, the optimum energy-storage performance were realized at x = 0.05 with the energy-storage density (W-rec) of 1.72 J/cm(3) and energy-storage efficiency (eta) of 85.6% at 105 kV/cm, accompanied with the excellent temperature stability and fatigue performance. The results demonstrated that BNBLT-xAN system was a promising lead-free candidate for energy-storage applications.
