The barium and strontium titanate (BST) ceramics have been used with great success as excellent dielectrics in the construction of high voltage (HV) commercial ceramic capacitors with reduced dimensions because of their high dielectric constant. However, the main point of this paper is to investigate other type of ceramic known as PZT (Lead Zirconate Titanate) normally used as piezoelectric sensors in industrial applications. The idea herein is to use the PZT ceramics as HV dielectrics for applications in high-energy storage systems by de-poling their piezoelectric properties in order to avoid dielectric damage and losses at high frequencies. For this, de-poled PZT-4 ceramic samples (30 mm × 2 mm) were submitted to HV tests, in which their dielectric breakdown strength and dielectric constant variation with the applied voltage were assessed. These results obtained confirmed the use of PZT in applications that require reasonable dielectric constant stability (< 15 %) with voltage and HV dielectric breakdown (40 kV/cm) for compact high-energy storage devices.

Sr0.7Bi0.2TiO3 (SBT), a kind of lead-free relaxor ferroelectric, is attracting more and more attention for pulse energy storage applications due to the low remnant polarization and high energy storage efficiency (h). However, relatively low dielectric breakdown strength (DBS) limited the recoverable energy storage density (Wrec). Herein, CaTiO3 with high intrinsic DBS was introduced in SBT. The novel solid solutions (1-x)SBT-xCT with x = 0 - 0.15 shows pure pseudo-cubic perovskite structure. When x = 0.05, the maxium polarization are improved, and the CT doping decreases the average grain size, leading to an enhanced DBS. A high energy storage properties of 1.59 J/cm3 with the h of 87.4% at 220 kV/cm is achieved in 0.95SBT-0.05CT, which demonstrates that this 0.95SBT-0.05CT is prospective materials for energy storage application.
