However, real-world applications are limited by the lack of effective mechanisms to strip electrolyte ions from solvent atoms and control their interactions and charge exchange with the layered electrode materials. Here, we discover the ion polar rotation within sub-nanometer interlayer space of two-dimensional MXene sheets by directly imaging interlayer ionic structure and measuring the local charge transfer. Unlike common ion desolvation, ion polar rotation rearranges solvent molecules and creates more exposure of intercalated ions, eliminating the need for long-range ion diffusion and desolvation. This effect enhances ion-electrode charge transfer at a unique interlayer spacing for each solvent. We demonstrated the efficacy of the polar rotation mechanism by designing a hierarchically structured MXene electrode with the optimal interlayer spacing, which shows Li⁺ storage capacitance of up to 310 F<!--> <!-->g⁻¹ (744 F cm⁻³) in LiTFSI/PC system and good rate performance.</div></div>","PeriodicalId":304,"journal":{"name":"Electrochemistry Communications","volume":"176 ","pages":"Article 107959"},"PeriodicalIF":4.7,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144089498","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the impact produced by doping Zr⁴⁺ on the structural, optical, morphological, magnetic and dielectric properties of Sr_0.7Bi_0.2(Ti_1-x Zr_x)O₃ ceramics has been investigated with respect to the frequency range of 1KHz to 1 MHz. According to the X-ray diffraction patterns, the base sample is a member of the space group pm-3 m and has a cubic structure. Using a scanning electron microscope (SEM), the samples' surface appearance and average grain size (0.493–0.381 μm) were examined. The difference of ionic radius between Ti⁴⁺ and Zr⁴⁺ ions have been observed to cause a decrease in grain size with Zr⁴⁺ doping. The FTIR study confirms the presence of metal‑oxygen bond and functional groups. The observed peak emission at 710 nm corresponds to the excitation energy of 1.76 eV in photoluminescence spectra. The UV visible absorption spectra results, the band gape energy (E_g) drops from 4.83 eV to 4.43 eV with an increasing the Zr⁴⁺ contents. The magnetic properties of Sr_0.7Bi_0.2(Ti_1-xZr_x)O₃ 0.00 ≤ x ≤ 0.60 ceramics at room temperature is increases with Zr⁴⁺ content, due to lattice distortions, improved exchange interactions, and oxygen vacancies that facilitate magnetic ordering, In addition to increasing domain wall pinning, Zr⁴⁺ doping decreases the grain size, which qualifies these ceramics for use in electromagnetic devices and magnetic storage. The dielectric properties of the prepared samples were strongly dependent on the frequencies, temperature, and as well as on concentration. The dielectric constant's temperature and content variations are most likely caused by the charge carrier hopping process and thermally induced dipolar relaxation. The overall best results are appropriate for applications using wireless devices.</div></div>","PeriodicalId":304,"journal":{"name":"Electrochemistry Communications","volume":"176 ","pages":"Article 107962"},"PeriodicalIF":4.7,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144099039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
