Abstract

Using the component materials barium titanate (BaTiO₃, BT), strontium titanate (SrTiO₃, ST), and sodium bismuth titanate [(Na_1/2Bi_1/2)TiO₃, NBT], anti-ferroelectric lead-free ceramics of (1-x)[0.94NBT-0.06BT]-xST have been fabricated using conventional techniques. The microstructure, electrical properties, and energy-storage performance of the obtained ceramics were investigated in detail. It was determined that the addition of ST can enhance the difference between the maximum polarization (P_max) and remnant polarization (P_r), resulting in the improvement of the energy-storage properties. The maximum recoverable energy density of 0.98Jcm^-3 with a relatively high efficiency of 82% was achieved under 90kVcm^-1 at x=0.30, which also displayed excellent energy-storage stability in the temperature range from room temperature to 120°C.
