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.

“…The ability to cold sinter multilayers with a tape cast formulation, using the binder polyalkylene carbonate (QPAC) was previously demonstrated; this then becomes the natural choice for this initial investigation into multilayer processing. [33][34][35] This is a very attractive candidate as it can be removed under a thermal decomposition process at temperatures as low as 120 °C in air and nitrogen atmospheres. Under the debinding decomposition process QPAC produces CO 2 and H 2 O that evolve within the particle mixture of BaTiO 3 and the transient phase.…”

This paper reviews the synthesis of BaTiO3-based ceramic and composites through the cold sintering process. Cold sintering is a densification process that works with a low-temperature mechanism known as pressure solution creep. This provides several opportunities to fabricate BaTiO3 into new composite structures that could provide important advanced dielectric properties. Here we revisit the challenges of densifying a material such as BaTiO3 that has incongruent dissolution. We consider the issues of surface chemistry, selection of transient flux, core–shell designs in BaTiO3, co-sintering with polymers in the grain boundaries and the technical challenges associated with incorporating all these ideas into tape casting steps for future fabrication of multilayer device structures.

Perspectives and challenges for lead-free energy-storage multilayer ceramic capacitors

The growing demand for high-power-density electric and electronic systems has encouraged the development of energy-storage capacitors with attributes such as high energy density, high capacitance density, high voltage and frequency, low weight, high-temperature operability, and environmental friendliness. Compared with their electrolytic and film counterparts, energy-storage multilayer ceramic capacitors (MLCCs) stand out for their extremely low equivalent series resistance and equivalent series inductance, high current handling capability, and high-temperature stability. These characteristics are important for applications including fast-switching third-generation wide-bandgap semiconductors in electric vehicles, 5G base stations, clean energy generation, and smart grids. There have been numerous reports on state-of-the-art MLCC energy-storage solutions. However, lead-free capacitors generally have a low-energy density, and high-energy density capacitors frequently contain lead, which is a key issue that hinders their broad application. In this review, we present perspectives and challenges for lead-free energy-storage MLCCs. Initially, the energy-storage mechanism and device characterization are introduced; then, dielectric ceramics for energy-storage applications with aspects of composition and structural optimization are summarized. Progress on state-of-the-art energy-storage MLCCs is discussed after elaboration of the fabrication process and structural design of the electrode. Emerging applications of energy-storage MLCCs are then discussed in terms of advanced pulsed power sources and high-density power converters from a theoretical and technological point of view. Finally, the challenges and future prospects for industrialization of lab-scale lead-free energy-storage MLCCs are discussed.
