AI 中文摘要
钠基超离子导体（NaSICON）的固体电解质（SEs）于1976年首次被引入，并迅速因其优异的离子电导率而受到认可。尽管在开发用于全固态电池（ASSBs）的薄电解质方面已投入大量努力，但仅有少数钠基SEs被成功制备为薄膜。这些薄膜因其降低的电阻而尤为理想，电阻通常随SE厚度的增加而增大。通过将SEs的厚度减小至纳米尺度，其离子电导率可显著提升。在本研究中，NASICON复合材料首先采用混合氧化物技术，使用行星球磨机制备成颗粒形式，并通过固相法在1300 °C下合成。所得颗粒用作低能离子设施中的溅射靶，以制备连续的NASICON纳米薄膜。为探究离子注入对NASICON电学性能的影响，使用CANAM基础设施（NPI Řež）的Tandetron加速器，以1.1 MeV能量和不同注量对制备的薄膜进行Ni离子轰击。通过电化学阻抗谱（EIS）分析合成及注入薄膜的电学性能。本文呈现了描述辐照对NASICON性能影响的结果。
英文摘要
Solid electrolytes (SEs) for sodium-based superionic conductors (NaSICON) were first introduced in 1976 and quickly recognized for their excellent ionic conductivity. While considerable effort has been made to develop thin electrolytes for all-solid-state batteries (ASSBs), only a few sodium-based SEs have been successfully fabricated as thin films. These thin films are particularly desirable for their reduced electrical resistance, which typically increases with the thickness of the SE. By reducing the thickness of the SEs to the nanometer scale, their ionic conductivity can be significantly enhanced. In this study, the NASICON composite was initially prepared in the form of pellets using the mixed oxide technique with a planetary ball mill and synthesized by the solid-state method at 1300 °C. The resulting pellets were used as sputtering targets in a low-energy ion facility to prepare continuous NASICON nanofilms. To explore the effect of ion implantation on the electrical properties of NASICON, the prepared films were bombarded with Ni ions at 1.1 MeV and varying fluences, using the Tandetron accelerator at the CANAM infrastructure (NPI Řež). The electrical properties of both the synthesized and implanted films were analyzed through electrochemical impedance spectroscopy (EIS). The results, describing the impact of irradiation on NASICON's properties, are presented here.
