Abstract

The effects of temperature and electric field-induced structural modifications on the energy storage properties of 0.95[0.94Bi0.5Na0.5TiO3-0.06BaTiO3]-0.05K0.5Na0.5TiO3 (BNT-BT-5KNN) ceramics were investigated. For this purpose, dielectric and ferroelectric properties were measured on unpoled and poled ceramics in a wide range of temperature. The stabilization of a ferroelectric phase during DC poling produced remarkable differences in the temperature dependence of permittivity, loss, current-polarization-electric field loops and energy density. As a consequence of a reversible transition induced by an alternating electric field, competitive energy density with those of other lead-based bulk ceramics recently developed was obtained, indicating bismuth-based perovskites as potential lead-free systems for energy storage applications.
