“…Besides, the dielectric strength in this work is evaluated under dc field condition, which is close to the actual operating state of the pulsed capacitors. However, the P‐E loop is generally performed under ac field condition, and the ac dielectric strength is usually lower than dc dielectric strength due to the dielectric loss …”

CaTiO₃ linear dielectric ceramics with greatly enhanced dielectric strength and energy storage density

et al. 2017

CaTiO 3 is a typical linear dielectric material with high dielectric constant, low dielectric loss, and high resistivity, which is expected as a promising candidate for the high energy storage density applications. In the previous work, an energy density of 1.5 J/cm 3 was obtained in CaTiO 3 ceramics, where the dielectric strength was only 435 kV/cm. In fact, the intrinsic dielectric strength of CaTiO 3 is predicted as high as 4.2 MV/cm. Therefore, it should be a challenge issue to enhance the dielectric strength and energy storage density of CaTiO 3 ceramics by optimizing the microstructures. In the present work, dense CaTiO 3 ceramics with fine and uniform microstructures are prepared by spark plasma sintering, and the greatly enhanced dielectric strength (910 kV/cm) and energy storage density (6.9 J/cm 3 ) are obtained. This can be ascribed to the improved resistivity and thermal conductivity, associated with the fine and uniform microstructures. The different post-breakdown features of CaTiO 3 ceramics prepared by different process well interpret why the enhanced dielectric strength is achieved in the SPS sample. The energy storage density can be further improved to 11.8 J/cm 3 by introducing the amorphous alumina thin films as the charge blocking layer, where the dielectric strength is 1188 kV/cm.

“…The maximum W rec and W dis are 19.3 J/cm 3 and 15.8 J/cm 3 at 1400 kV/cm, respectively. Clearly, the values of the W dis are smaller than that of W rec , which likely ascribes to the distinct polarization responses to DC and AC voltages of dielectrics . With the increase in the electric field, the value of η displays a decreased trend, due to the significant increase in the remanent polarization and coercive field at high electric field .…”

Flexible antiferroelectric (AFE) Pb0.94La0.04Zr0.97Ti0.03O3 (PLZT) thick‐film capacitors were fabricated on nickel foil substrates using sol‐gel method. The thick PLZT film shows pure perovskite phase with dense microstructure. The discharge energy‐storage properties of the thick PLZT film are directly evaluated by the resistance‐inductance‐capacitance (RLC) circuit. The maximum value of the discharge energy‐storage density (Wdis) is 15.8 J/cm3 at 1400 kV/cm and 90% of the corresponding energy is released in a short time of about 250 ns. In addition, the Wdis and discharge time could be adjusted by the bent radius of the film, which provides a simple and feasible solution for the regulation of the electrical performance. Furthermore, the flexible AFE film exhibits good mechanical properties under cycling tests with bending radii down to 2.5 mm and 1500 rounds. This work shows a critical significance in fabricating flexible AFE capacitors for application in modern electronics and electrical power systems.

“…Some lead-contained material systems, such as lead lanthanum zirconate titanate (PLZT)-based ceramics, have outstanding dielectric and ferroelectric properties. [10][11][12] Nevertheless, recently, as the Pb element does harm human health, the research on novel lead-free material systems has aroused intense interest.

Lead-free ferroelectric ceramics are very suitable for electrostatic energy storage capacitors due to their outstanding characteristics of high charge-discharge speed, high power density, and environmental friendliness. Herein, a novel material system as (1−x)Na 0.5 Bi 0.5 TiO 3-xCaZr 0.5 Ti 0.5 O 3 (NBT-CZT, x = 0, 0.05, 0.10, 0.12, 0.15, and 0.20) was designed and prepared for dielectric energy storage ceramics. It demonstrated that the CZT additives induced a phase transition for the NBT ceramics, from ferroelectric to relaxor ferroelectric. In particular, extremely high stored energy storage density (6.92 and 5.37 J/cm 3), high recoverable energy storage density (4.77 and 4.37 J/cm 3), and moderate efficiency (69.0% and 81.4%) were achieved in both the samples of x = 0.12 and x = 0.15, respectively. The ceramics exhibited excellent stability of energy storage performance covering a wide temperature (25°C-200°C) and frequency (0.5-50 Hz) range, and also fatigue cycles up to 10 5. Additionally, the NBT-CZT ceramics had a fast discharge speed (t 0.9 < 100 ns) and high power density (24.2 MW/cm 3 , E = 100 kV/cm, x = 0.15), and the charge-discharge process remained stable even when the measured temperature was up to 160°C. Therefore, the NBT-CZT ceramics have the potential to be utilized in electrostatic energy storage applications.
