摘要

The performance of pulse power capacitors for energy storage has been elevated to a higher level with the dynamic development of the electronic component industry in recent years. This work improves the energy density and power density (PD) in the (Bi0.5Na0.5)0.7Sr0.3TiO3 (BNST) by introducing Mg0.85Bi0.1ZrO3 (MBZ). The ceramic grain size was significantly reduced by the introduction of MBZ, and the breakdown electric field (Eb) of the ceramics was also enhanced. The recoverable energy storage density (Wrec) of 0.90BNST-0.10MBZ ceramics is 2.67 J/cm3 at an electric field of 208 kV/cm, at which time the polarization difference reaches 39.52 μC/cm2 with an energy storage efficiency (η) of 63.55%. Simultaneously, the 0.90BNST-0.10MBZ ceramics exhibit excellent electrical stability under test conditions ranging from 20 to 140 °C and 1 to 200 Hz. Furthermore, the 0.90BNST-0.10MBZ ceramics were found to exhibit a PD of 13.02 MW/cm3 and a discharge time of 1.368 μs at an electric field of 160 kV/cm. These characteristics indicate that ceramics with 0.90BNST-0.10MBZ have a possible application in exceptionally powerful devices.
