dc.description.abstract | This study introduces a Na+ fluorinated halide nanocomposite solid electrolyte (HNSE), ZrO2-2Na(2)ZrCl(5)F, synthesized through a mechanochemical reaction using Na2O. This HNSE exhibits a substantial improvement in Na+ conductivity (2.1 x 10(-5) S cm(-1) at 30 degrees C) compared to Na2ZrCl5F (2.0 x 10(-7) S cm(-1)). The significant reduction in ionic conductivity of Na2ZrCl5F relative to Na2ZrCl6 (2.0 x 10(-5) S cm(-1)) is elucidated through synchrotron pair distribution function (PDF) analysis. Structural insights, including the fine structure of the ZrO2 nanograins embedded in an amorphous Na2ZrCl5F matrix and the potential O-substituted interphase, are revealed through X-ray absorption spectroscopy, PDF, and cryogenic transmission electron microscopy. Fluorinated HNSEs offer exceptional electrochemical oxidative stability up to 5 V (vs Na/Na+), enabling high-voltage cathode applications. Na0.66Ni0.1Co0.1Mn0.8O2||Na3Sn all-solid-state cells using ZrO2-2Na(2)ZrCl(5)F as the catholyte demonstrate enhanced performance at 30 degrees C compared to cells using Na2ZrCl6 (47.4% capacity retention after 100 cycles vs 35.3% using Na2ZrCl6). | - |
