Dielectric ceramic capacitors, with the advantages of high power density, fast charge-discharge capability, excellent fatigue endurance, and good high temperature stability, have been acknowledged to be promising candidates for solid-state pulse power systems. This review investigates the energy storage performances of linear dielectric, relaxor ferroelectric, and antiferroelectric from the viewpoint of chemical modification, macro/microstructural design, and electrical property optimization. Research progress of ceramic bulks and films for Pb-based and/or Pb-free systems is summarized. Finally, we propose the perspectives on the development of energy storage ceramics for pulse power capacitors in the future.

“…Therefore, by decreasing the T s of BNT below room temperature, its r P can be reduced and rec W can be improved. Qiao et al [68] introduced La 3+ into the Sr 2+ site of the BNT-ST ceramics: this is because La 3+ doping plays a role in decreasing the grain size and delaying saturation of the polarization electric field in BNT-based ceramics, as shown in Fig. 11 Additionally, defect control is another effective approach to improve the comprehensive energy-storage properties.…”

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.

“…The bismuth sodium titanate (Bi 0.5 Na 0.5 TiO 3 or BNT) has been identified as a potential energy storage material because it has a large spontaneous polarization (P s ) over 40 µC/cm 2 [6], which originates from the hybridization of Bi 6p and O 2p orbitals [4]. However, the BNT has large P r at ambient temperature and high coercive field (E c ∼ 73 kV/cm) [6,7], which limit its energy storage density resulting in a small recoverable energy storage density (W rec ) and a low η values [4,8,9]. The BNT-based ceramics have also been widely used in the energy-storage devices because their permittivity and polarization are higher than other linear dielectrics [10].…”

“…The BNT-based ceramics have also been widely used in the energy-storage devices because their permittivity and polarization are higher than other linear dielectrics [10]. For the sake of promoting the energy storage properties with decreasing P r value, the modulation of BNT by other perovskite compositions was identified [9].…”

In order to clarify the optimal sintering conditions, the effects of processing parameter on phase evolution, physical, microstructure, dielectric, ferroelectric, and energy storage density properties of bismuth sodium titanatestrontium bismuth titanate ceramics (or BNT-SBT) were investigated. The studied ceramics were fabricated via a conventional mixed oxide method and sintered at temperatures ranging from 1100-1175°C under normal atmosphere for 3 h dwell time with a heating/cooling rate of 5°C/min. The XRD data revealed that the coexisting rhombohedral and tetragonal phases were observed in all of the ceramics. With increasing sintering temperature, the cubic-rich phase was dominated; and the average grain size tended to increase. For the ceramics sintered at 1150°C, the good density (5.74 g/cm 3 ), dielectric ( max = 3510, tan δ = 0.0501, T F-R = 73.80°C, T m = 273°C), and ferroelectric (P r = 3.05 µC/cm 2 , E c = 7.69 kV/cm) were obtained. In addition, the obtimum sintering temperature of 1150°C was also found to improve the energy storage density properties (W = 0.94 J/cm 3 , η = 89.93% at 125°C, and E = E max ).
