The research addresses the challenge of optimizing relaxor ferroelectric behavior to exhibit a thin <i>P-E</i> loop at this practically relevant electric field. In the study, X-ray diffraction (XRD) and <i>Rietveld</i> refinement confirmed a coexistence of rhombohedral (<i>R</i>3<i>c</i>) and tetragonal (<i>P</i>4<i>bm</i>) phases, with increasing tetragonal phase content as KTN55 doping increased. Scanning Electron Microscopy (SEM) revealed a significant reduction in grain size from 4.34 μm to 0.73 μm. Dielectric measurements showed typical relaxor ferroelectric behavior with frequency-dependent anomalies at <i>T</i>_s, <i>T</i>_m and a flat dielectric response in the range of 75° C to 310° C for higher doping levels. Ferroelectric measurements indicated a steady reduction in remnant polarization (<i>P</i>_r) and coercive field (<i>E</i>_<i>c</i>) with increasing KTN55 content. The composition with <i>x</i> = 0.06 demonstrated optimal performance, with a remnant polarization of 0.96 µC/cm², a maximum polarization of 14.42 µC/cm², and a discharge efficiency of 97.86% under a field of 43 kV/cm. The Recoverable energy density (<i>W</i>_rec) reached 0.295 J/cm³. All of the produced composite samples demonstrated stability without breakdown under the maximum applied electric field of 200 kV/cm, as limited by the instrument. Thus, their breakdown field exceeds this value, qualifying them as high breakdown field ceramics. These results suggest that BNT-KTN55 ceramics, particularly with <i>x</i> = 0.06, is a promising candidate for high-efficiency energy storage applications such as capacitors and pulse power devices.</p></div>","PeriodicalId":625,"journal":{"name":"Journal of Electroceramics","volume":"53 2","pages":"243 - 256"},"PeriodicalIF":2.6,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144914585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The composites were prepared using the solution casting technique, and various properties were examined under different experimental conditions. The composites were characterized for various properties, including structural, microstructural, vibrational (FTIR-Fourier Transform Infrared), dielectric, and ferroelectric properties. XRD (X-ray Diffraction) analysis was used to observe the electroactive β-phase fraction in the composites. The microstructure of the composites was examined to understand the arrangement of the components. FTIR analysis provided insights into the mechanism of enhancing the β-phase and the interaction between negatively surface-charged ions of the PZT/BNT (BP) filler and the CH₂ dipole of the PVDF polymer matrix. Dielectric constant variation with PZT/BNT (BP) filler concentrations was studied. The interplay between functional properties and the β-phase, likely related to ferroelectric behaviour, was discussed in detail. The electroactive β-phase fraction was observed to increase in the ternary composite PVDF/PZT/BNT (BPP). For PVDF/PZT (PP) composite concentration, β-phase fraction decreased because of percolation effect. The study explores the comprehensive characterization of ferroelectric ceramic-polymer composites, focusing on the interaction between the polymer matrix and piezoceramic (PZT/BNT) (BP) filler. The observed changes in properties, especially the electroactive β-phase fraction, provide valuable insights into the composition-structure-property relationships in these composites.

Herein, MoO₂/N-doped carbon nanoribbons with rich oxygen vacancies (OVs) have been prepared via hydrothermal method followed by thermal annealing in Ar atmosphere. The composite nanoribbons, as novel anode materials, demonstrate excellent electrochemical performance with a specific capacity of 132.6 mAh g^− 1 at 5 A g^− 1 for SIBs and 130.2 mAh g^− 1 at 1 A g^− 1 for PIBs, along with a high Coulombic efficiency of approximately 100% over 2000 cycles for SIBs and 10,000 cycles for PIBs.

A built-in electric field at heterojunction interface is beneficial for Na/K ions diffusion across the interface.

This work proposes a simple strategy for preparing Fe/Fe₃C particle modified thin-layer carbon-coated Si/SiO_x composite materials using a mixture of resorcinol formaldehyde (RF) precursor pyrolysis and ultrasonic treatment (referred to as C@Si/SiO_x-Fe/Fe₃C, abbreviated as CSSO-Fe/Fe₃C).

Comprehensive characterization and electrochemical studies have elucidated the interface compatibility and structural stability mechanisms induced by the small amount of Fe/Fe₃C doping and carbon coating, which explain the high capacity and stable cycling performance. Furthermore, when paired with LiCoO₂ cathode, the assembled LiCoO₂||CSSO-Fe/Fe₃C coin-type full battery has a capacity of 80.7 mAh g⁻¹ and a capacity retention rate of 76.6% after 200 cycles at 1.0 C.
