MnO2-doped 0.955NaNbO3-0.045La(Nb1/3Mg2/3)O3 ceramics were prepared through a conventional method. The effects of MnO2 amount on the dielectric property, and the phase transition behavior and energy storage performance were studied. The introduction of MnO2 can obviously improve sintering performance and effectively stabilize anti-ferroelectric phase, accompanied with the variation of phase transition temperature. An enhanced recoverable energy storage density of 2.63 J·cm−3 with efficiency of 66.8% was obtained at RT when 1.5% MnO2 was applied. This sample also demonstrated attractive thermal stability in energy storage from 30 °C–90 °C. In addition, the coexistence of positive and negative electrocaloric effect was observed due to the emergence of anti-ferroelectric phase. A further advantage of the thermal hysteresis phenomenon possesses abilities to enhance dielectric and energy storage properties. This will contribute to the promotion of NaNbO3-based lead-free dielectric capacitors.

“…Dielectric capacitors are widely regarded in energy storage applications because they possess high power density, rapid charge/discharge speed, high efficiency, good thermal stability, and a high cycle fatigue lifetime. − Generally, energy storage performance can be described by parameters of the charge energy density ( W ), recoverable energy density ( W rec ), and energy efficiency (η). They are calculated by the following formulas: , …”

Antiferroelectric (AFE) materials are regarded as one of the most hopeful candidates for pulse power capacitors due to their higher saturation polarization, lower remnant polarization, high power density, and fast charge− discharge speed. It is difficult to simultaneously obtain excellently the recoverable energy density (W rec ) and the energy efficiency (η) at present. In this work, PbHfO 3 AFE ceramics are processed by the cold isostatic pressure (CIP) method. It is confirmed that the CIP method can reduce the grain sizes and ameliorate the ceramic's microstructure and thus increase the average electric breakdown field strength up to 336 kV/cm compared to 269 kV/cm by the conventional solid-state (CS) method. An excellent W rec of 11.4 J/cm 3 with a high η of 88.2% is achieved in the PbHfO 3 ceramics by the CIP method at 342 kV/cm. Furthermore, it exhibits good stability in temperature and frequency and has a high discharge current density of 1557 A/cm 2 and power density of 233 MW/cm 3 with a rapid discharge speed (112 ns). Moreover, dielectric properties and Raman spectra of the sample by the CIP method are discussed and demonstrate that the sample encounters a phase transformation at 150 and 195 °C. The result in this work indicates that the PbHfO 3 AFE ceramics by the CIP method will be a potential candidate for pulse power capacitors.
