摘要：

The (1 - x)[0.935(Bi0.5Na0.5)TiO3-0.065BaTiO(3)]-xBa(Zr0.3Ti0.7)O-3 (BNT-BT-xBZT) ceramics with high-energy storage properties were designed and characterized. All the BNT-BT-xBZT ceramics exhibit a pure perovskite structure. The grain size of ceramics becomes larger as the BZT content increases. Enhanced energy density performances (W-rec = 1.9 J/cm(3), eta = 86%) are achieved for the BNT-BT-0.4BZT ceramics at 210 kV/cm. Specifically, the energy stored in the material can be rapidly released within 0.27 mu s. Excellent temperature stability with the variation of W-rec less than 7% is realized in a wide temperature range from 20 to 140 degrees C. Moreover, the energy storage performances have good reliability after 10(5) electric field cycles. The high-energy storage performances indicate that the BNT-BT-0.4BZT ceramics are promising candidates in pulsed-power applications.
