“…The average grain size, experimental densities (ρ m ), theoretical density (ρ th ), and relative densities (ρ r ) with content x are also displayed in Table 1. The ρ r is calculated using the following formula: 32

\begin{equation*} {\rho }_r = \frac{{{\rho }_m}}{{{\rho }_r}} \times 100\% ,\end{equation*}

where ρ m is measured via the Archimedes drainage method, and ρ th is calculated according to the formula

{\rho }_{th} = \frac{{M \times Z}}{{V \times {N}_A}}

( M , Z , V , and N A are the molecular mass, formula units per unit cell, the volume of the unit cell and Avogadro constant, respectively). All the samples show consistent structures with distinct grain boundaries and a compact microstructure (ρ r > 95%), which is advantageous for improving the energy storage properties.…”

The development of ceramics with superior energy storage performance and transparency holds the potential to broaden their applications in various fields, including optoelectronics, energy storage devices, and transparent displays. However, designing a material that can achieve high energy density under low electric fields remains a challenge. In this work, (1−x)Bi0.5Na0.5TiO3−xBaZr0.3Ti0.7O3:0.6mol%Er3+ (abbreviated as (1−x)BNT−xBZT:0.6%Er3+) ferroelectric translucent ceramics were prepared by the conventional solid‐state reaction method. The energy storage properties of (1−x)BNT−xBZT:0.6%Er3+ are systematically investigated under low electric fields by modulating the coupling between coexisting phase structures of polar nano regions. Especially, 0.9BNT–0.1BZT:0.6%Er3+ ceramic exhibits an ultra‐high maximum polarization (Pmax = 66.3 µC/cm2), large recoverable energy storage density (Wrec = 2.95 J/cm3), total energy storage density (W = 5.75 J/cm3), and energy storage efficiency (η = 51.3%) under 190 kV/cm. The sample also exhibits excellent thermal stability (30‐150°C) and transmittance (∼28%). This work could facilitate the advancement of energy storage systems that are more efficient and cost‐effective, and also provide opportunities for the design and manufacture of novel devices.

“…A specific amount of stored energy of such capacitor is consumed during the depolarization process, designated as energy loss density ( W loss ). [ 39 ] Introducing lower ZnO@APTES content in PVDF (30 vol%) increases recoverable energy storage density and the difference between W rec and W loss (Figure 11A). Capacitors with high efficiency should possess a sufficient difference between W rec and W loss , where W rec > W loss .…”

Polymer composite films are ideal materials for advanced energy storage capacitor in electrical systems. Therefore herein, we fabricated a novel series of polyvinylidene fluoride (PVDF) based composites embedded with well dispersed ZnO@APTES {surface modified zinc oxide with (3‐Aminopropyl) triethoxysilane (APTES)} nanoflake (0, 20, 30, 40, 50) vol% through solution casting method. Hydrothermally synthesized two‐dimensional ZnO was pre‐treated with H2O2 and surface modified with APTES for perfect distribution of nanoflake into PVDF matrix. Surface modification and high aspect ratio morphology of ZnO@APTES enhanced the interfacial interaction between organic PVDF and inorganic ZnO through reduction in heterogeneity between them. Surface functionalization reduced the dielectric loss and improved the overall energy storage performance. Investigation of electrical properties proclaimed incorporating 30 Vol% ZnO@APTES in PVDF as optimized loading due to its appreciable Wrec (recoverable energy density) about 3.2 J/cm3. Relative comparison of the energy storage density (Wrec) of PVDF/ZnO@APTES (30) vol% with recent published works established its enhanced capacitive response and its future application in energy storing portable device.

Depletion of fossil fuels and increase in pollution through chemical batteries trigger the development of self‐powered devices based on flexible piezoelectric nanogenerators. Biocompatible piezoelectric PVDF nanocomposites merged with piezoelectric fillers like ZnO, KNN, and BaTiO3 reproduce amended piezoelectric current, contributing to the safe application as biosensors and flexible industrial devices. Optimized loading, precise selection, and variating the surface chemistry of piezoelectric filler, along with fabrication schemes comprising different structural configurations of composites, considerably influence its potential for application as energy harvester. Also, optimized processing condition upgrades dielectric constant, energy storage density, and reduces dielectric loss, thereby plummeting energy dissipation even after prolonged usage. Consequently, this paper reviews the principles, properties, fabrication techniques, and market application of PVDF composites. A detailed relationship of significant electrical properties of PVDF composites with its fabrication methods and piezoelectric parameters of fabricated PVDF composites with reported real‐life wearable, implantable, and industrial‐based portable piezoelectric devices are discussed in detail along with tabulated data for clear understanding of structure‐property relationship. Again, market strategy for establishing flexible PVDF composite as a piezoelectric nanogenerator has been discussed. An in‐depth knowledge is provided for procuring affordable futuristic large‐scale PVDF‐based nanogenerators exhibiting affordable market worth.This article is protected by copyright.
