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.

“…Later, energy storage properties in BaTiO 3 -BiMeO 3 (Me denotes a single trivalent ion or average complex trivalent ions) have been extensively studied. [89][90][91][92][93][94][95][96][97] Notably, the effects of the Me ion on energy storage performance are not in complete accord. Energy storage performance is related to the weakened nonlinearity and relatively strong relaxor behavior, as discussed by M. Wei et al 93 An alternative method for improving the microstructure in BaTiO 3 -based materials is the addition of glass for its low melting point.…”

The excellent energy-storage performance of ceramic capacitors, such as high-power density, fast discharge speed, and the ability to operate over a broad temperature range, gives rise to their wide applications in different energy-storage devices. In this work, the (Pb 0.98 La 0.02 )(Zr 0.55 Sn 0.45 ) 0.995 O 3 (PLZS) antiferroelectric (AFE) ceramics are prepared via a unique rolling machine approach. The field-induced multiphase transitions are observed in polarization-electric field (P-E) hysteresis loops. All the PLZS AFE ceramics possess high energy-storage densities and discharge efficiency (above 80%) with different sintering temperatures. Of particular significance is that an ultrahigh recoverable energy-storage density of 10.4 J cm -3 and a high discharge efficiency of 87% are achieved at 40 kV mm -1 for PLZS ceramic with a thickness of 0.11 mm, sintered at 1175 °C, which are by far the highest values ever reported in bulk ceramics. Moreover, the corresponding ceramics exhibit a superior discharge current density of 1640 A cm -2 and ultrafast discharge speed (75 ns discharge period). This great improvement in energy-storage performance is expected to expand the practical applications of dielectric ceramics in numerous electronic devices.
