Abstract

A novel perovskite lead-free solid solution of (Ba_0.06Bi_0.47Na_0.47)_1-xLa_xTi_1-yZr_yO₃ were designed by dual-substitution of La³⁺ and Zr⁴⁺ for (Ba_0.06Bi_0.47Na_0.47)²⁺ and Ti⁴⁺. The frequency-, temperature- and fatigue-dependent energy storage properties of the materials were investigated. After the dopings of La³⁺ and Zr⁴⁺, the crystal structure of the ceramics remains unchanged; and tetragonal and rhombohedral phases coexist in all ceramics which exhibit a relaxor phase transition. The co-substitution of La³⁺ and Zr⁴⁺ leads to the high dielectric breakdown strength (DBS), large spontaneous polarization (P_s) and small remnant polarization (P_r) of the materials. The optimum energy storage properties are achieved at x/y = 0.02/0.04, giving high recoverable energy storage density of W_rec ~1.55 J/cm³, excellent energy storage efficiency of ƞ ~72.6% and large dielectric breakdown strength of DBS ~136 kV/cm. Furthermore, the ceramic with x/y = 0.02/0.04 possesses superior durability of frequency (~2–60 Hz), fatigue (~ 10³) and temperature (~ 25–245 °C).
