Multifunctional energy storage and piezoelectric properties of 0.65Pb(Mg_1/3Nb_2/3)O₃–0.35PbTiO₃ thick films on stainless-steel substrates

The miniaturization of electronic devices and power systems requires the fabrication of functional components in the form of micrometer-sized thick films. A major challenge is the integration of functional ceramics with metals, which are considered incompatible with high-temperature ceramic processing. To overcome the integration barrier, an aerosol deposition (AD) spray-coating method based on room temperature deposition can be used. By employing the AD method, we were able to deposit relaxor-ferroelectric 0.65Pb(Mg1/3Nb2/3)O3–0.35PbTiO3 ceramic thick films on low-cost stainless-steel substrates. The as-deposited films were dense, with ~97% of the theoretical density. Moreover, the post-deposition annealing at 500 °C did not result in any microstructural changes. Compared to the as-deposited films, the annealed films exhibit improved energy storage and electromechanical properties. The annealed thick films achieve a recoverable energy density of 15.1 J⋅cm−3 at an electric field of 1350 kV⋅cm−1 and an electric-field cycling stability of 5 million cycles. A piezoelectric response was detected through the entire film thickness by piezoelectric force microscopy. Macroscopic displacement measurements revealed a maximum relative strain of 0.38% at 1000 kV⋅cm−1, corresponding to inverse effective piezoelectric coefficient of ~40 pm⋅V−1. In this study, we overcame the integration challenges and demonstrated the multifunctionalization of future ceramic-metal structures, as the deposited thick films on stainless steel exhibit energy storage capability and piezoelectric properties.

“…This provides a good incentive to replace Pbbased piezoceramics in sensor applications with Pb-free counterparts as g 33 is the figure of merit for sensors. [135] Notably, the highest g 33 values are seen for the representative BF-based piezoceramics owing to their moderate d 33 and low permittivity. Moreover, the BF-based piezoceramics have a higher T c and a lower Φ compared to the PZTs which is attractive for the sustainable production of high-temperature sensor materials.…”

Piezoelectric materials are widely used in electromechanical coupling components including actuators, kinetic sensors, and transducers, as well as in kinetic energy harvesters that convert mechanical energy into electricity and thus can power wireless sensing networks and the Internet of Things (IoT). Because the number of deployed energy harvesting powered systems is projected to explode, the supply of piezoelectric energy harvesters is also expected to be boosted. However, despite being able to produce green electricity from the ambient environment, high‐performance piezoelectrics (i.e., piezoelectric ceramics) are energy intensive in research and manufacturing. For instance, the design of new piezoceramics relies on experimental trials, which need high process temperatures and thus cause high consumption and waste of energy. Also, the dominant element in high‐performance piezoceramics is hazardous Pb, but substituting Pb with other nonhazardous elements may lead to a compromise of performance, extending the energy payback time and imposing a question of trade‐offs between energy and environmental benefits. Meanwhile, piezoceramics are not well recycled, raising even more issues in terms of energy saving and environmental protection. This paper discusses these issues and then proposes solutions and provides perspectives to the future development of different aspects of piezoceramic research and industry.

“…Piezoelectric materials, such as lead zirconate titanate (PZT) have been broadly utilized in sensors, actuators, ultrasound tranducers, and energy harvesters because of their property of converting electric energy into mechanical energy, and vice versa (Hooper et al, 2021; Lv et al, 2015; Quinsaat et al, 2020; Sakthivel and Arockiarajan, 2012). However, inherent brittleness, high sensitivity to cracking, and high acoustic impedance can often generate limitations in obtaining a monolithic piezoelectric material which satisfies the multiple demands of a specified application at the same time (Jain et al, 2015; Lv et al, 2015; Sakthivel and Arockiarajan, 2012; van den Ende et al, 2013).…”

This research investigates the effect of adding graphene nano-sheets (GNSs) on the elastic and piezoelectric responses of PZT-7A piezoelectric fiber/polyimide hybrid composites. The constructional feature of this hybrid composite is such that unidirectional PZT-7A fibers are embedded into the GNS-filled polyimide material. A nested micromechanical modeling strategy based on the Mori-Tanaka scheme is developed to predict the effective properties of PZT-7A/GNS/polyimide hybrid composites. Parametric studies are performed in order to examine the influences of volume fraction, agglomeration and rolling-up of GNSs, and PZT-7A volume fraction on the piezoelectric hybrid composite coefficients. The results indicate that the elastic and piezoelectric properties of PZT-7A/polyimide composites can be improved by the uniform dispersion of GNSs. However, it is observed that the formation of GNS agglomeration into the polyimide matrix has a serious negative effect on the equivalent properties of piezoelectric hybrid composites. The present predictions are also compared with other results reported in the literature. It is believed that the modeling approach and outcomes of this research may help to design these kinds of novel and highly promising piezoelectric hybrid composites.
