“…For example, the value of η for the PNZST (100) gradually decreased from 58 % to 56 % with a change from 444 kV cm -1 to 2488 kV cm -1 . The Wrec and BDS in this study were compared with promising energy storage materials which were recently reported on [49][50][51][52][53][54][55][56][57][58], as shown in Figure 7(c). The high BDS (> 3000 kV cm -1 ) enabled the dielectric material to have high energy storage performance, but such a high working electric field means strict requirements on the reliability of capacitors.…”

An all-inorganic Pb0.99Nb0.02(Zr0.85Sn0.13Ti0.02)0.98O3 (PNZST) antiferroelectric (AFE) thin film was designed to enhance its energy-storage performance by adjusting its orientation. Using a radio frequency (RF) magnetron sputtering technology, 450-nm-PNZST AFE films with (111), (110), and (100) crystal orientations were successfully prepared. All the films showed a dense microstructure and the highly preferred orientations were determined by the orientation of the bottom electrodes. Moreover, the preferred orientation of the AFE thin film had a great influence on the dielectric and energy-storage properties. Meanwhile, the energy storage density of the PNZST AFE thin film with the (100) orientation reached 33.7 J cm-3 , which was 43 % higher than that of PNZST AFE thin film with a (111) orientation. All of these results shed light on how the energy-storage performance of PNZST AFE thin films can be enhanced and optimized by adjusting its orientation. This offers a new strategy and innovation, which opens up a route to practical applications in micro-energy-storage systems. INDEX TERMS Orientation, antiferroelectric thin film, energy-storage.

“…The dielectric properties and energy densities of several types of dielectrics are summarized in Table 1. [47][48][49][50][51] Compared to the inorganic dielectric film and the polymer-based nanocomposites, the crystalline-amorphous multilayer films achieve the highest energy density through the introduction of the crystalline SBT and amorphous AO layers. Therefore, it is an effective way to achieve simultaneous improvements in the breakdown strength and dielectric constant through structural modulation.…”

Over the past few decades, the ever-increasing global demand for energy supply and serious environmental challenges have affected the world considerably in many ways. 1-3 Developing advanced energy-storage technologies is an effective way to overcome the above problems and this option has been extensively investigated in the recent past. 4 Dielectric-based capacitors exhibit superior advantages owing to their ultrahigh power density and fast charge-discharge speed in comparison with chemical batteries and electrochemical supercapacitors. 2,5,6 However, their energy densities are much lower than that of chemical energy-storage systems, 7,8 which has become the main obstacle for their use in high-efficiency energy-storage devices. 9 Therefore, dielectric materials with high energy-storage densities are the need of the hour.

“…First, the P(VDF-CTFE) powder (Solef 31508, Solvay) was dissolved in dimethylformamide (DMF, Aladdin, 99.9%) solution and stirred for 10 h. Then, the ST NWs, ST@SiO 2 NWs with optimal volume fraction (3 vol.%) 37 were dispersed into above mixed solution under stirred and ultrasound to homogeneously mix the components. The nanocomposite film was then cast on a clean glass substrate using the obtained mixed solution.…”

The development of advanced dielectric film materials with high energy storage performance is of critical significance for pulsed power capacitor applications. Nevertheless, the low discharged energy density ([Formula: see text]) of current dielectric film material restricts their further application. In this work, core-shell structured SrTiO3@SiO2 nanowires (ST@SiO2 NWs) fillers are fabricated based on interface engineering for high [Formula: see text]. The optimized SiO2 insulating layer could effectively confine the mobility of space charge carriers in the interfacial zone between ST NWs and thick SiO2 insulating layer, thus reducing the interfacial polarization between the interface of nanofillers/polymer, which could be used to optimize the electric field strength and electric displacement of the corresponding nanocomposite. As a result, this nanocomposite film simultaneously exhibits enhanced maximum applied electric field ([Formula: see text]) and ([Formula: see text]-[Formula: see text]) values, thus releasing an ultrahigh discharged energy density of 14.7[Formula: see text]J/cm3 at 390[Formula: see text]MV/m, which is 99% higher than that of the conventional ST/P(VDF-CTFE) (without SiO2 coating) nanocomposite, and it is almost 2.5 times that of pure P(VDF-CTFE). This work demonstrates the superiority of the core-shell structured paraelectric nanowire in enhancing the energy storage performance of dielectric film capacitors, which is expected to guide the design of advanced energy-storage nanocomposites.
