Abstract

With the continuous development of modern technology, the demand for energy storage materials is also increasing. Ferroelectric energy storage materials, as a new type of material with broad application prospects, have unique advantages in storing, transmitting, and converting energy. In this work, (1-x)BaTiO₃-xBi(Mg_2/3Ta_1/3)ferroelectric ceramics were synthesized in a solid-state solution. The sample of x=0.18 (0.88BT-0.12BMT) has excellent energy storage density. The excellent energy density of 3.24J/cm³ at 260 kV/cm and the energy efficiency of 83 % at room temperature for 0.88BT-0.18BMT ceramics were achieved.
