“…The first thing that can be observed is that the permittivity of sandwich-structure composite dielectric lies between pristine PVTC and PMMA. The permittivity of the sandwich-structure composite dielectric increases with the increase of the volume fraction of PVTC, which is consistent with the capacitor series model [ 7 , 46 ]. Additionally, the dispersion in 9-1 composite dielectric is most obvious.…”

Improving the energy storage density of dielectrics without sacrificing charge-discharge energy storage efficiency and reliability is crucial to the performance improvement of modern electrical and electronic systems, but traditional methods of doping high-dielectric ceramics cannot achieve high energy storage densities without sacrificing reliability and storage efficiency. Here, an all-organic energy storage dielectric composed of ferroelectric and linear polymer with a sandwich structure is proposed and successfully prepared by the electrostatic spinning method. Additionally, the effect of the ferroelectric/linear volume ratio on the dielectric properties, breakdown, and energy storage is systematically studied. The results show that the structure has good energy storage characteristics with a high energy storage density (9.7 J/cm3) and a high energy storage efficiency (78%). In addition, the energy storage density of the composite dielectric under high energy storage efficiency (90%) is effectively improved (25%). This result provides theoretical analysis and experience for the preparation of multilayer energy storage dielectrics which will promote the development and application of energy storage dielectrics.

“…156 Ceramics with multilayers also influence the energy storage density property, as an example, 5Ba 0.7 Sr 0.3 TiO 3 −SrTiO 3 (BST-ST) multilayers displayed the ideal energy storage density (2.3 J/cm 3 ) with dielectric breakdown strength (220 kV/cm). 157 Li et al prepared 2 wt % MgO-modified Ba 0.4 Sr 0.6 (Ti 0.996 Mn 0.004 )O 3 by solid-state reaction method, which displayed a great energy storage density (∼2 J/cm 3 ), good energy efficiency (88.6%), and high breakdown strength (300 kV/cm). 158 For exploiting the BNTbased ceramic capacitors, Xu et al presented lead-free (Bi 0.465 Na 0.465 Ba 0.07 ) 1−x La x TiO 3 (BNBLT, x = 0−0.04) ceramics, which showed decreasing remnant polarization and coercive field with increasing La content.…”

Recent developments in various technologies, such as hybrid electric vehicles and pulsed power systems, have challenged researchers to discover affordable, compact, and super-functioning electric energy storage devices. Among the existing energy storage devices, polymer nanocomposite film capacitors are a preferred choice due to their high power density, fast charge and discharge speed, high operation voltage, and long service lifetime. In the past several years, they have been extensively researched worldwide, with 0D, 1D, and 2D nanofillers being incorporated into various polymer matrixes. However, 1D nanofillers appeared to be the most effective in producing large dipole moments, which leads to a considerably enhanced dielectric permittivity and energy density of the nanocomposite. As such, this Review focuses on recent advances in polymer matrix nanocomposites using various types of 1D nanofillers, i.e., linear, ferroelectric, paraelectric, and relaxor−ferroelectric for energy storage applications. Correspondingly, the latest developments in the nanocomposite dielectrics with highly oriented, surface-coated, and surface-decorated 1D nanofillers are presented. Special attention has been paid to identifying the underlying mechanisms of maximizing dielectric displacement, increasing dielectric breakdown strength, and enhancing the energy density. This Review also presents some suggestions for future research in low-loss, high energy storage devices.

“…Comparatively, MLCC chips can successfully overcome the problems in bulk ceramics and thin films since MLCC chip is fabricated with tens or hundreds dielectric layers alternately arranged. Gao et al has designed xBa 0.7 Sr 0.3 TiO 3 ‐SrTiO 3 (BST‐ST) multilayer ceramics with different BST layers. The breakdown strength and energy storage density of multilayer ceramics were 220 kV/cm and 2.3 J/cm 3 .…”

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.
