“…New energy is undergoing vigorous development to reduce the carbon emissions and meet the long-term goal of carbon neutrality. Energy storage devices are in urgent demand in new energy industries. − Ferroelectric ceramics are of great interest in the energy storage applications, especially in the form of multilayer ceramic capacitors (MLCCs), because of the high capacitance and fast charge–discharge capability. , However, the energy density of ferroelectric ceramics is always limited by the relatively low breakdown strength. Further, high-temperature dielectric materials have drawn much attention as the electronic equipment is required to be operated at a high temperature beyond 200 °C in many emerging industries, such as aeronautics and astronautics, deep oil drilling, new-energy vehicle, and gas exploration. , A practical challenge for ferroelectric ceramics is the rapidly increased leakage current at high temperatures, which leads to the sharply increased dielectric loss and greatly reduced energy efficiency.…”

BNT (Bi 0.5 Na 0.5 TiO 3 )-based ferroelectric ceramics have drawn much attention in energy storage applications due to the high saturation polarization and good temperature stability. However, the reduction of Ti 4+ caused by the volatilization of Bi and Na elements during high-temperature sintering is a huge problem. A multivalent element (Mn) is adopted in this work to prevent the reduction of Ti 4+ and thus enhance the polarization and breakdown strength simultaneously. Various contents of MnO 2 -doped 0.76Bi 0.5 Na 0.5 TiO 3 −0.04SrZrO 3 −0.2NaNbO 3 (BNTSZNN) ceramics were prepared by the ramp-to-spike sintering method. As the content of MnO 2 increases, the reduction of Ti 4+ is effectively decreased, inhibiting the degradation of ferroelectricity and decreasing the leakage conductance. As a result, an ultra-high discharge energy density of 7.05 J/cm 3 is achieved in the BNTSZNN-0.15MnO 2 ceramic at 387 kV/cm. Importantly, the BNTSZNN-0.15MnO 2 ceramic shows excellent temperature stability. The change of the discharge energy density between 30 and 160 °C is less than ±4% under the applied field of 120 kV/cm. Additionally, the variation in the capacitance of the BNTSZNN-0.15 MnO 2 ceramic is less than ±15% over the temperature range from −58 to 450 °C, with a high room-temperature dielectric permittivity of 1507. All the above characteristics indicate the potential of BNTSZNN-0.15MnO 2 as a high-temperature and high-voltage ceramic dielectric.

PbHfO 3 was found with antiferroelectricity early and identical to PbZrO 3 in many aspects but much less attention was received. In the present work, the PbHfO 3 -based ceramics with compositions of Pb 0.97 La 0.02 (Hf 1−x Ti x )O 3 (PLHT, 0 ≤ x ≤ 0.1) were fabricated, and their antiferroelectricity was investigated. All the compositions have an initially antiferroelectric (AFE) phase and by introducing Ti content, the AFE phase is destabilized. Typical AFE-like double polarizationelectric field (P-E) loop was observed in compositions with 0 ≤ x ≤ 0.08. When x = 0.10, the composition is initially AFE but remains ferroelectric (FE) phase after the removal of the external electric field, resulting in an FE-like single P-E loop. The temperature dependence of phase transition and multiple phase transition behavior in PLHT was also studied. This work revealed the antiferroelectricity in PLHT with low Ti content. In addition, the potential application of PLHT for energy storage and conversion was also discussed. A recoverable energy density of 7.1 J/cm 3 and efficiency of 78.5% were achieved in Pb 0.97 La 0.02 HfO 3 at 300 kV/cm.
