“…BaTiO 3 (BT)-based ceramics have been considered promising lead-free candidates for electrostrictive applications due to their higher Q 33 values compared to other lead-free ferroelectric systems. ,,,− However, the electrostrictive performance of BT polycrystalline ceramics is typically inferior to that of BT single crystals due to the statistical averaging of multiple orientations in the polycrystalline structure. While a large Q 33 value of 0.11 m 4 C –2 has been reported for a BT single crystal along its [001] direction (Figure a), its high T C limits its practical electrostrictive application at room temperature (RT).…”

The electrostrictive effect, which induces strain in ferroelectric ceramics, offers distinct advantages over its piezoelectric counterpart for high-precision actuator applications, including anhysteretic behavior even at high frequencies, rapid reaction times, and no requirement for poling. Historically, commercially available electrostrictive materials have been lead oxide-based. However, global restrictions on the use of lead in electronic components necessitate the exploration of lead-free electrostrictive ceramics with a high strain performance. Although various engineering strategies for producing materials with high strain have been proposed, they typically come at the expense of increased strain hysteresis. Here, we describe the extraordinary electrostrictive response of (Ba0.95Ca0.05)(Ti0.88Sn0.12)O3 (BCTS) ceramics with ultrahigh electrostrictive strain and negligible hysteresis achieved through texture engineering leveraging the anisotropic intrinsic lattice contribution. The BCTS ceramics exhibit a high unipolar strain of 0.175%, a substantial electrostrictive coefficient Q 33 of 0.0715 m4 C–2, and an ultralow hysteresis of less than 0.8%. Notably, the Q 33 value is three times greater than that of high-performance lead-based Pb(Mg1/3Nb2/3)O3 electrostrictive ceramics. Multiscale structural analyses demonstrate that the electrostrictive effect dominates the BCTS strain response. This research introduces a novel approach to texture engineering to enhance the electrostrictive effect, offering a promising paradigm for future advancements in this field.

“…For the purpose of boosting the progress of the energy storage and conversion technology, the electronics industry advancements call for lighter, more flexible, and much more higher-performance energy storage materials. − Because of their ability to charge and discharge quickly, capacitors are widely used in hybrid vehicles as the basic component of the power system. , Researchers have made great progress in the study of dielectric polymers and ceramic polymer composites in recent years. − The key parameter for the performance of dielectric materials is the energy storage density ( U e ), which can be expressed by U e = ∫ E d P . According to the formula, the U e of dielectric materials is related to the electric strength ( E ) and polarization ( P ), and P is proportional to the dielectric constant (ε r ) .…”

A variety of applications can be found for high-temperature film capacitors, including energy storage components and pulsed power sources. In this work, in order to increase the energy density ( U e ), poly(vinylidene fluoride-chlorotrifluoroethylene-double bond) (P-DB) is introduced into poly(methyl methacrylate) (PMMA) to manufacture composite films by a solution casting process. In the case of the pure PMMA film, there is significant improvement in the polarization ( P max ) and breakdown field ( E b ) of the composite film. These improvements can effectively increase the U e of the composite film at room temperature and the elevated temperature. The results show that at an elevated temperature of 90 °C and at 350 MV/m, the U e of 40 vol % P-DB reaches 8.7 J/cm 3 , and the efficiency (η) of 77% is also considerable. Compared with biaxially oriented polypropylene (2.0 J/cm 3 ), the proposed film exhibits 4 times enhancement in the energy storage density, meaning that it can be an energy storage capacitor with huge potential at high temperatures.

“…Pressure generated by a diamond anvil cell (DAC) can exceed megabars and induce tremendous changes in the materials properties of structures, optics, magnetics, and electrics. − All of the changes have their own exclusive research methods. For example, pressure-induced structural phase transition has always been studied with synchrotron radiation X-ray diffraction (XRD) , and superconducting transition can be detected with electrical resistance − and magnetic susceptibility measurements. ,, However, electrostriction, which is a basic phenomenon in all insulators or dielectrics to describe electric field/polarization-induced strain, − has hardly been involved in high-pressure studies, especially with DAC. The chief reason is related to DAC sample configuration.…”

Electrostrictive Effect of Materials under High Pressure Revealed by Electrochemical Impedance Spectroscopy

et al. 2021

View full text Add to dashboard Cite

Because electrostrictive materials are completely sealed and confined in a diamond anvil cell (DAC), their strain and atomic displacement excited by electric field cannot be in situ measured by general measurements. Therefore, an experimental study on the electrostrictive properties of materials under high pressures becomes an unexploited field. In this paper, we study the electrostrictive effect of CaZrO3 under high pressures with electrochemical impedance spectroscopy. In the impedance spectra, the electrostrictive effect is presented clearly in the form of an inductive loop. Fitted with the equivalent circuit method, information about strain and its evolution with pressure can be obtained.
