“…To better understand the phase evolution, Raman spectra of the MLCC chip were investigated at different temperatures, as shown in Figure . It has been reported that the Raman spectra of pure BaTiO 3 has four phonon modes peaks at ~180 cm −1 [A1(TO 1 )], ~303 cm −1 [B1+E], ~513 cm −1 [A1(TO 3 )] and ~717 cm −1 [A1+E], respectively . The resonance peak at ~180 cm −1 disappeared when the temperature increased to room temperature.…”

“…The resonance peak at ~180 cm −1 disappeared when the temperature increased to room temperature. A broadening of the ~305 cm −1 peak and a reduction in the ~717 cm −1 peak suggest a decreasing in the tetragonality with increasing temperature . When the temperature reached 175°C, the left part of the ~305 cm −1 peak and the ~717 cm −1 peak nearly disappeared.…”

BaTiO 3 -(Bi 0.5 Na 0.5 )TiO 3 (BTBNT)-based multilayer ceramic capacitor (MLCC) chips with the inner electrodes being Ag0.6/Pd0.4 are prepared by a roll-to-roll casting method. The BTBNT-based MLCC chips with ten-dielectric layers can be sintered very well at a low temperature of 1130°C via two-step sintering (TSS). X-ray diffraction (XRD) and transmission electron microscope (TEM) resultsshow that MLCC chips are a core-shell structure with two phases coexistence.The core exhibits a tetragonal phase at room temperature and then gradually changes into a cubic phase when the temperature increases above T c (175°C).While, the shell exhibits a pseudocubic phase at all tested temperature from 25°C to 500°C. BTBNT-based MLCC chips exhibit a broad temperature stability and meet the requirement of Electronic Industries Association (EIA) X9R specifications. In terms of energy storage performance, a large discharge energy density of 3.33 J/cm 3 can be obtained at 175°C under the applied electric field of 480 kV/ cm. Among all tested temperature ranging from −50°C to 200°C, the energy efficiency of all chips is higher than 80%, even under a high applied electric field.The experimental results indicate that this novel BTBNT-based X9R MLCCs can be one of the most promising candidates for energy storage applications, especially operated in high temperature.

Electroceramics for High-Energy Density Capacitors: Current Status and Future Perspectives

et al. 2021

Materials exhibiting high energy/power density are currently needed to meet the growing demand of portable electronics, electric vehicles and large-scale energy storage devices. The highest energy densities are achieved for fuel cells, batteries, and supercapacitors, but conventional dielectric capacitors are receiving increased attention for pulsed power applications due to their high power density and their fast charge–discharge speed. The key to high energy density in dielectric capacitors is a large maximum but small remanent (zero in the case of linear dielectrics) polarization and a high electric breakdown strength. Polymer dielectric capacitors offer high power/energy density for applications at room temperature, but above 100 °C they are unreliable and suffer from dielectric breakdown. For high-temperature applications, therefore, dielectric ceramics are the only feasible alternative. Lead-based ceramics such as La-doped lead zirconate titanate exhibit good energy storage properties, but their toxicity raises concern over their use in consumer applications, where capacitors are exclusively lead free. Lead-free compositions with superior power density are thus required. In this paper, we introduce the fundamental principles of energy storage in dielectrics. We discuss key factors to improve energy storage properties such as the control of local structure, phase assemblage, dielectric layer thickness, microstructure, conductivity, and electrical homogeneity through the choice of base systems, dopants, and alloying additions, followed by a comprehensive review of the state-of-the-art. Finally, we comment on the future requirements for new materials in high power/energy density capacitor applications.
