摘要

High recoverable energy density (W_rec ∼ 2.1 J/cm³) was obtained in (0.7 - x)BiFeO₃-0.3Ba"₃-xBi(Zn_2/3Nb_1/3)O₃ + 0.1 wt % Mn₂O₃ (BF-BT-xBZN, x = 0.05) lead-free ceramics at <200 kV/cm. Fast discharge speeds (<0.5 μs), low leakage (∼10^-7 A/cm²), and small temperature variation in W_rec (∼25% from 23 to 150 °C) confirmed the potential for these BiFeO₃-based compositions for use in high energy density capacitors. A core-shell microstructure composed of a BiFeO₃-rich core and Ba"₃-rich shell was observed by scanning and transmission electron microscopy which may contribute to the high value of energy density. In addition, for x = 0.005, a large electromechanical strain was observed with S_pos = 0.463% and effective d₃₃∗ ∼ 424 pm/V, suggesting that this family of ceramics may also have potential for high strain actuators.
