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.

“…The meanings of X, Y, x and y in formula (10) are the same as formula ( 9), combined with the previous algorithm equation, an analytical formula of equivalent constant can be obtained. The solution method of inclusion theory can better reflect the actual situation of the material, and the accuracy of the solution is relatively high, but it also has shortcomings [19].The calculation and problem-solving of inclusion theory are relatively cumbersome, and sometimes only numerical methods can be used to solve equations.…”

“…These changes use an action effect to form a driving force for the mechanical vibration system in the transducer and make it enter an oscillation state. In turn, the medium in contact with the mechanical oscillation control system of the transducer is caused to oscillate and radiate sound waves to the center of the medium [10]. Through some physical effects, the charge or magnetism in the energy storage element of the transducer has formed a certain change, and this leads to the formation of a voltage and current corresponding to the sound signal at the electrical output end of the transducer [11].…”

Piezoelectric ultrasonic transducer is the most important functional device in the field of ultrasound, as an important part of piezoelectric ultrasonic transducer-piezoelectric material, the improvement of its performance plays an important role in promoting the innovation and development of piezoelectric ultrasonic transducers. This article aims to conduct a finite element study based on the 1-3 piezoelectric composite ferroelectric material of the smart medical ultrasonic diagnostic transducer. In this article, the working principle and function of the ultrasonic transducer are explained first. The ultrasonic transducer is classified, and the FEM analysis of the 1-3 piezoelectric composite ferroelectric material and the ANSYS FEM analysis method are introduced. The influence of PZT volume fraction, aspect ratio and the number of primitives on the finite element model of the 1-3 spherical-crown piezoelectric composite is mainly discussed, and then verified by experiments and ANSYS performance analysis of ultrasonic diagnostic transducers. The research results show that the thickness electromechanical coupling factor of the 1-3 piezoelectric composite material is affected by the thickness electromechanical coupling coefficient of the piezoelectric phase material, the volume fraction of the piezoelectric phase, and the width-to-thickness ratio. When the aspect ratio is increased to 0.7, the electromechanical coupling coefficient of the thickness with a volume fraction of 80% is reduced by 79%.The electromechanical coupling coefficient of the thickness with a volume fraction of 60% is reduced by 73%, and the electromechanical coupling coefficient of the thickness with a volume fraction of 20% is reduced by 68%.

(Pb, La)(Zr, Ti)O3 (PLZT) with antiferroelectric properties can be applied as a capacitor whose capacitance increases in a high electric field. From this, we obtained a high sintering density at 950 °C by adding low-temperature sintering additives, 8.0 wt% of PbO and 2.5 wt% of ZnO, simultaneously to a (Pb0.88, La0.12)(Zr0.86, Ti0.14)O3 composition. The change in electrical characteristics was confirmed in terms of Sn4+ substitution, resulting in no change in the sintering density by Sn4+ substitution. However, as the amount of Sn4+ substitution increases, the dielectric constant gradually decreases from 1300 to 700, and the grain size decreases from about 4 to 1 µm in terms of microstructure. In the crystal structure analysis, the general formation of a single perovskite structure was confirmed. The results of the hysteresis curve measurement revealed that the breakdown electric field increases from 4 to 9 kV·mm−1 as the amount of Sn4+ substitution gradually increases. However, polarization decreases in the same way as the permittivity trend. The composition exhibits excellent electrical properties when the ratio of Sn4+ is 0.4: a high energy storage density of 3.5 J·cm−3, energy efficiency of 80%, and breakdown electric field of about 8.5 kV·mm−1.
