Environmentally friendly lead-free dielectric ceramics have attracted wide attention because of their outstanding power density, rapid charge/dischargerate, and superior stability. Nevertheless, as a hot material in ceramic capacitors, the energy storage performance Na0.5Bi0.5TiO3-based has been not satisfactory higher remnant polarization value low breakdown strength, which is problem that must be urgently overcome. In this work, (1 - x) (0.6Na0.5Bi0.5TiO3 0.4Sr0.7Bi0.2TiO3)...
The sandwich-structured KNN-BZT/P(VDF-HFP) nanocomposites were prepared by solution casting method. When the breakdown strength reached 565 MV m −1 , excellent energy storage performance ( U d = 21.39 J cm −3 η 70.54%) was obtained.
Polymer composite flexible films with high dielectric constant are highly desirable in electronic and electrical industry. Higher loading of the ceramic fillers is usually needed order to realize constant. However, such composites exhibit low breakdown strength poor mechanical processing properties. In this work, by incorporating aspect ratio surface-hydroxylated Ba0.6Sr0.4TiO3 nanotubes (BST NT) prepared via electrospinning into a polyvinylidene-fluoride (PVDF) matrix, PVDF nanocomposite...
With the ultrahigh power density and fast charge–discharge capability, a dielectric capacitor is an important way to meet increase in demand for energy storage system such as pulsed systems (PPS). The BaTiO3-based considered one of candidates PPS due its high permittivity. However, with continuous miniaturization PPS, further increases thermal stability capacitors. Thus, this work describes new performance multilayer ceramic (MLCC) BaTiO3–xBi(Li0.5Nb0.5)O3 (BT–xBLN) (0.0 ≤ x 1.0) PPS. On...
All-organic composite materials with excellent energy storage performance were prepared by solution casting method. The density reaches 5.34 J cm −3 (at E b = 580 MV m −1 ), and the charge discharge efficiency is 85% at 150 °C.
New piezoelectric ceramics, 0.71 BiFe 1− x ( Ni 1/2 Ti ) O 3 −0.29 BaTiO +0.6 wt% MnO 2 [ BFNT – BT ] = 0–0.09), were fabricated using conventional mixed‐oxide method. It was found that the introduction of BNT into BF ‐ system caused insignificant change in crystal structure, which is a single‐phase perovskite structure. However, an obvious variation microstructure took place. The ceramics with composition 0.03 showed enhanced piezoelectric, electromechanical, and ferroelectric properties...
Lead-free [(Bi0.5Na0.5)0.93Ba0.07]1-xLaxTi1-yZryO3 (BNBLTZ) ceramics were investigated for energy storage applications. In order to adjust its properties, the La and Zr co-doping contents varied at 0.01 ≤ x, y 0.04. BNBLTZ show a single phase perovskite structure without transition after co-doping. The compact uniform microstructure with similar grain morphology different sizes is obtained. remnant polarization coercive field decrease increase of additions, density increases drastically....
Abstract LiNiPO 4 (LNP) ceramics were synthesized using a conventional solid‐state reaction method and different sintering temperatures. Differential scanning calorimetry (DSC), thermogravimetric (TG) analysis, X‐ray diffraction (XRD) measurements indicated that single‐ phase olivine ( Pnma , No. 62) was formed above 750°C, dense LNP ceramic with theoretical density of more than 95% obtained at 825°C. Raman far‐infrared (IR) vibrational modes assigned discussed in detail. The intrinsic...
A series of (Bi1–xYx)VO4 (0.4 ≤ x 1.0) ceramics were synthesized using the traditional solid-state reaction method. In composition range 0.4 1.0, a zircon-type solid solution was formed between 900 and 1550 °C. Combined with our previous work (scheelite monoclinic phases coexist in < 0.40), pseudobinary phase diagram BiVO4–YVO4 is presented. As decreased from 1.0 to 0.40, microwave permittivity (εr) increased linearly 11.03 30.9, coincident an increase temperature coefficient resonant...
