  • Piezoelectric and ferroelectric properties of
           Na[math]Bi[math]Ti4O[math]–BaTiO3 composite ceramics with Mg doping

    • Authors: Chaobin Jiang, Chao Ma, Qian Luo, Kanghui Liu, Lu Qin, Zhentao Wu, Wanqiang Cao, Yong Chen
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      As one of the representatives of lead-free NBT ceramics, Na[math]Bi[math]Ti4O[math] has still attracted much attention due to its excellent dielectric properties and has become the focus of research. However, its piezoelectric properties are far from satisfactory. In order to improve the piezoelectric properties of Na[math]Bi[math]Ti4O[math], Na[math]Bi[math]Ti[math]MgxOy–BaTiO3 (NBTM–BT) composite ceramics were synthesized by a conventional mixed oxide route and sintered at 1040∘C through two-step method. We optimized the electrical properties of NBTM–BT by changing the stoichiometric ratio of Mg content and studied its microscopic mechanism. The piezoelectric coefficient ([math]) is stable at about 20 pC/N. Moreover, the maximum remanent polarization (2[math]) of the ceramic is 3.08[math][math]C/cm2 with the coercive field of 18.01[math]kV/cm. The dielectric constant and dielectric loss for Na[math]Bi[math]Ti[math]Mg[math]–BT composite ceramic were found to be 486 and 0.17 at 10[math]kHz, respectively. The characteristic peaks of BT and Na[math]Bi[math]Ti4O[math] can be observed clearly from the X-ray diffraction analysis. SEM analysis showed that all samples were well crystallized. Consequently, the piezoelectric and ferroelectric properties of Na[math]Bi[math]Ti4O[math]–BT composite ceramic will be enhanced much by Mg doping, which means it has a wider range of applications in electronic devices such as piezoelectric devices.

      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      In the present work, the comparative study of the electric response of Sn2P2S6 films to the visible light action was carried out without and under external electric field. The light flux modulated by a chopper induces the integral response comprising time-dependent photoelectric and photovoltaic components. It was shown that spontaneous polarization influences the electric response characteristics.

  • Physics of ferroelectric differential capacitance based upon free energy,
           and implications for use in electronic devices

    • Authors: C. M. Krowne
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      In this paper, it is shown that for stable, steady state operation of devices typical of microwave and millimeter were electronics, no negative differential capacitance is possible with conventional thinking. However, it may be possible, with strain engineering of materials, to obtain some if not all elements of the differential capacitance tensor which are negative. Rigorous derivations are provided based upon analyzing the physics using thermodynamic phenomenological free energy. It should be emphasized that, even with strain engineering, and possible discovery of some negative capacitive elements, stable operation will not be obtained because the thermodynamics precludes it.

  • Effect of sulfur doping on the dielectric properties of Sb2Se3 system

    • Authors: Ragab Mahani, E. A. El-Sayad
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      In this paper, we report the effect of sulfur doping on the electrical and dielectric properties of semiconducting Sb2Se2S over wide ranges of temperatures (298–473[math]K) and frequencies (42–106[math]Hz). Sb2Se2S system has been prepared by the direct fusion and cooling cycle of a mixture of the constituent elements, in stoichiometric ratio and purity 99.999%, in vacuum-sealed silica tubes. X-ray analysis showed a decrease in the cell parameters [math], [math] and [math] upon doping with sulfur. However, the pure and doped Sb2Se3 showed the single orthorhombic phase structure. The permittivity of Sb2Se2S showed a decrease with increasing frequency due to a decrease in the average bond strength. While, ac conductivity increased with the frequency increase, obeying the Jonscher’s universal dynamic law. The conductivity temperature dependence is well described by the correlated barrier hopping model. The activation energy calculated from DC conductivity is found at higher value (0.79[math]eV) as compared to that reported in the literature for other antimony selenide compounds. Accordingly, a new Sb2Se2S compound is suggested which may be useful for electronic devices.

  • Grain boundary effects on piezoelectric properties of the
           core–shell-structured BaTiO3@TiO2 ceramics

    • Authors: Xixi Li, Zhonghua Yao, Juan Xie, Zongxin Li, Hua Hao, Minghe Cao, Amjad Ullah, Atta Ullah, Abdul Manan, Hanxing Liu
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      Grain boundary effect on BaTiO3 has been widely investigated for several decades. However, all of them tailored the grain boundary by grain size of BaTiO3. In this case, a direct way was introduced to modify the grain boundary by coating technique to investigate the role of grain boundary in ferroelectric materials. Nonferroelectric phase TiO2 was employed to investigate grain boundary effects on the electrical properties of BaTiO3 piezoelectric ceramics. TiO2 coating can result in the reduction of piezoelectric and ferroelectric properties and the annealing process in oxygen can increase piezoelectric behavior of pure BaTiO3 due to valence state of Ti ions while that remains for Ti-modified composition possibly due to the increased grain boundary effect by impedance analysis. Compared with ferroelectric grain, grain boundary plays a critical role to impact the electrical properties of perovskite-type ferroelectric materials.

  • Improvements of dielectric properties and energy storage performances in
           BaTiO3/PVDF nanocomposites by employing a thermal treatment process

    • Authors: Yue-Mao Dang, Ming-Sheng Zheng, Jun-Wei Zha
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      The influence of thermal treatment on the dielectric properties and energy storage performances of a classical dielectric nanocomposite system (barium titanate/polyvinylidene fluoride PVDF) was discussed systematically. The results demonstrated that the permittivity of thermal treated nanocomposites increased and dielectric loss decreased compared with the untreated system. In addition, the energy density was also greatly improved due to the inclined residual polarization. For example, the energy density of the treated nanocomposite with 50[math]vol.% nanofillers was 3.14 times higher than the untreated nanocomposite at 50[math]MV/m. Moreover, the charge–discharge efficiency was also promoted from 6.36% to 56.89%. According to the viewpoint of microstructure, the improvement of the dielectric and energy storage properties would be ascribed to the suppression on void defects in the interphase of dielectric nanocomposite by employing the thermal treatment process. Finally, thermal treatment turns out to be a simple and an effective method to improve the dielectric performances and energy storage properties in the dielectric nanocomposites.

  • Improved dielectric energy storage performance of Pb-free
           0.5Na[math]Bi[math]TiO3-0.5SrTiO3 ceramics modified with CaO

    • Authors: Peng Chen, Leiyang Zhang, Ziyang Wang, Yifei Wang, Chunlin Song, Jinzhu Hu, Gang Liu, Yan Yan
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      CaO doped 0.5Na[math]Bi[math]TiO3 (NBT)-0.5SrTiO3 (ST) were prepared by a traditional solid-reaction method under various sintering temperatures. X-ray diffraction (XRD), electron scanning microscopy (SEM), and electrical measurements were employed to check the phases, microstructures, and energy storage properties. The doping of CaO can deeply affect the relaxation nature of NBT-ST ceramics. So the energy storage performance could be modified. Specially, sample with 1 at.% CaO exhibits a high energy storage density of 1.51[math]J/cm3. Any further details can be found within this study.

  • Structure, dielectric properties of low-temperature-sintering BaTiO3-based
           glass–ceramics for energy storage

    • Authors: Tong Wang, Yuanhao Wang, Haibo Yang, Ying Lin, Luo Kong, Shuya Gao, Fen Wang
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      The 0.85BaTiO3–0.15Bi(Mg[math]Nb[math])O3 (BTBMN) ceramics with low-melting-temperature B2O3–Na2B4O7–Na2SiO3 (BNN) glass addition were prepared by the solid state method. The composition of the glass–ceramics was BTBMN–[math] wt.% BNN ([math], 1, 3, 5, 7, 9, 12, 15; abbreviated as BG). The sintering characteristics, phase structure, microstructure, dielectric properties and energy storage properties were systematically investigated. The sintering temperature of BTBMN ceramics was greatly reduced by the addition of BNN glass. The second-phase BaTi(BO[math] was observed in the BG system until the glass content reached 15[math]wt.%. The addition of BNN glass significantly reduces the grain size of BTBMN ceramics. With the increase of BNN glass content, dielectric constant of BG glass–ceramics at 1[math]kHz gradually decreased, the maximum dielectric constant ([math] of BG glass–ceramics gradually decreased, while the temperature corresponding to the maximum dielectric constant ([math] increased, the ferroelectric relaxation behavior decreased and the temperature stability of the dielectric constant gradually improved. As the BNN glass content increased, the breakdown electric field strength (BDS) of BG glass–ceramics increased first and then decreased, and the polarization values reduced gradually, while the trend of energy storage performance is similar to BDS. When the BNN glass content was 3[math]wt.%, the energy storage properties of the BG glass–ceramics were optimal, and a recoverable energy storage density ([math]) of 1.26[math]J/cm3 and an energy storage efficiency ([math]) of 80.9% were obtained at the electric field strength of 220[math]kV/cm. The results showed that BG glass–ceramics were promising for energy storage capacitors.

  • Influence of Bi nonstoichiometry on the energy storage properties of
           0.93KNN–0.07BixMN relaxor ferroelectrics

    • Authors: Xiaoshuang Qiao, Xiaoshuai Zhang, Di Wu, Xiaolian Chao, Zupei Yang
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      Ceramic-based dielectric capacitors are becoming more and more important in electronic devices. The ceramics of 0.93K[math]Na[math]NbO3–0.07Bix(Mg[math]Nb[math])O3 (0.93KNN–0.07BixMN) ([math], 2/3, 0.75 and 0.95) were successfully fabricated by virtue of the solid reaction process in this work. The results showed that the amount of Bi content has a significant impact on the ceramics of 0.93KNN–0.07BixMN. XRD indicates that all specimens exhibit a pure perovskite structure and existing oxygen vacancy in the specimens. The mean grain size for all specimens belong to submicron scale, and the sample of [math] owns the smallest grain size is 0.11[math][math]m. The maximum dielectric constant increases but the phase transition temperature [math] exhibits a contrary tendency at 1[math]MHz with increasing Bi concentration. Besides, all ceramics are relaxor ferroelectric. The impedance analysis further revealed that the activation energy of the ceramics increases with Bi content. Eventually, the highest [math] of 58.8% and [math] of 1.30[math]J/cm3 are simultaneously achieved in the sample with [math]. Overall, we demonstrate in this work that stoichiometry control of Bi in 0.93KNN–0.07BixMN ceramics is a practical method to obtain the desired structural, dielectric and energy storage properties.

  • Improved dielectric constant and energy density of P(VDF-HFP) composites
           using NBT-[math]ST ([math], 0.10, 0.26) whiskers

    • Authors: Xuefan Zhou, Lu Wang, Guoliang Xue, Kechao Zhou, Hang Luo, Dou Zhang
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      The high-performance energy-storage dielectric capacitors are increasingly important due to their wide applications in high power electronics. Here, we fabricated a novel P(VDF-HFP)-based capacitor with surface-modified NBT-[math]ST ([math], 0.10, 0.26) whiskers, denoted as Dop@NBT-[math]ST/P(VDF-HFP). The influences of ST content, fillers’ volume fraction and electric field on the dielectric properties and energy-storage performance of the composites were investigated systematically. The results show that the dielectric constant monotonously increased with the increase of ST content and fillers’ volume fraction. The composite containing 10.0 vol% NBT-0.26ST whiskers possessed a dielectric constant of 39 at 1[math]kHz, which was 5.6 times higher than that of pure P(VDF-HFP). It was noticed that the D-E loops of the composites became thinner and thinner with the increase of ST content. Due to the reduced remnant polarization, the composite with 5.0 vol% NBT-0.26ST whiskers achieved a high energy density of 6.18[math]J/cm3 and energy efficiency of approximately 57% at a relatively low electric field of 200[math]kV/mm. This work indicated that NBT-0.26ST whisker is a kind of potential ceramic filler in fabricating the dielectric capacitor with high discharged energy density and energy efficiency.

  • High energy storage performance for dielectric film capacitors by
           designing 1D SrTiO3@SiO2 nanofillers

      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      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 ([math]) 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 [math]. 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 ([math]) and ([math]-[math]) values, thus releasing an ultrahigh discharged energy density of 14.7[math]J/cm3 at 390[math]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.

  • BiFeO3-BaTiO3: A new generation of lead-free electroceramics

    • Authors: Dawei Wang, Ge Wang, Shunsuke Murakami, Zhongming Fan, Antonio Feteira, Di Zhou, Shikuan Sun, Quanliang Zhao, Ian M. Reaney
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      Lead-based electroceramics such as Pb(Zr.Ti)O3 (PZT) and its derivatives have excellent piezoelectric, pyroelectric and energy storage properties and can be used in a wide range of applications. Potential lead-free replacements for PZT such as potassium sodium niobate (KNN) and sodium bismuth titanate (NBT) have a much more limited range of useful properties and have been optimized primarily for piezoelectric applications. Here, we review the initial results on a new generation of lead-free electroceramics based on BiFeO3-BaTiO3 (BF-BT) highlighting the essential crystal chemistry that permits a wide range of functional properties. We demonstrate that with the appropriate dopants and heat treatment, BF-BT can be used to fabricate commercially viable ceramics for applications, ranging from sensors, multilayer actuators, capacitors and high-density energy storage devices. We also assess the potential of BF-BT-based ceramics for electrocaloric and pyroelectric applications.

           energy storage applications

    • Authors: Feng Li, Jiwei Zhai, Bo Shen, Huarong Zeng
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      Increasing concern has been focused on the search for ecofriendly dielectric ceramics to meet the extensive demands of pulsed capacitors. Due to the advantages of high-energy storage density, efficiency, and excellent temperature stability, optimization of energy storage performance in dielectric ceramics has been a goal in the past decades. This review summarizes the recently reported progress in energy storage properties of typical perovskite-type lead-free ceramics. The advantages and shortcomings in the various kinds of ceramics are discussed. Finally, future prospects are presented to provide some guidelines for the exploration of new materials.

  • Structure and dielectric properties of NBT-[math]BT-ST lead-free ceramics
           for energy storage

    • Authors: Wen-Qin Luo, Zong-Yang Shen, Yuan-Ying Yu, Fu-Sheng Song, Zhu-Mei Wang, Yue-Ming Li
      Abstract: Journal of Advanced Dielectrics, Ahead of Print.
      ([math])(Na[math]Bi[math])TiO3-[math]BaTiO3-0.26SrTiO3 ([math]) (abbreviated as NBT-[math]BT-ST) lead-free ceramics were fabricated by a solid-state reaction method. The effect of Ba doping amount [math] on the structure and energy storage properties of NBT-[math]BT-ST ceramics were investigated. All the NBT-[math]BT-ST ceramics showed single perovskite structure with a pseudocubic phase. Ba doping effectively suppressed grain growth, in favor of forming small and uniform grains. The ceramics with a composition of [math], an optimized energy storage density ([math][math]J/cm3) and efficiency ([math]%), under an applied electric field of 50[math]kV/cm, should be a candidate for solid-state compact pulsed power capacitor materials.
