In the model that reproduces the stable structure during the fifth cycle charging at 25 and 60 °C, Li atoms in the transition metal (TM) layer, surrounded by Mn and not adjacent to Co, move toward the Li layer due to weak Li<img>O bonding, partially creating vacancies. The coordination number of Mn near these vacancies in the TM layer changed during charging. During discharging, the model in which Li ions were locally coordinated away from the vacancies in the TM layer was stable. In the 25 °C-charging model, compared to the pristine model, less changes were observed in Mn<img>O bonds within the Mn<img>O6 octahedra, which are most abundant in the TM layer. Furthermore, less distortion in the Mn-O₆ octahedra was observed, resulting in minimal changes to the host structure during charging and discharging. Therefore, compared to 60 °C, the cycle characteristics were evidently improved when charging and discharging at 25 °C.</div></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"421 ","pages":"Article 116793"},"PeriodicalIF":3.0,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143350263","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}

Sodium thiophosphate (Na3PS4) based solid electrolytes have shown excellent promise with relatively high ionic conductivity. In particular, the orthorhombic γ – Na3PS4 phase exhibits superionic behavior (ionic conductivity ∼10–50 mS/cm) compared to that of the cubic (ionic conductivity ∼0.1 mS/cm) and tetragonal (ionic conductivity ∼0.001–0.01 mS/cm) Na3PS4 phases at room temperature. However, the reported γ – Na3PS4 phase is stable only at high temperatures and, therefore, does not contribute towards improving ionic conductivity at room temperature. In this study, we report ab initio molecular dynamics calculations to gain fundamental insights into the superionic behavior of the γ – Na3PS4 phase. These insights were applied to simulate and develop correlations between structure and ionic conductivity in amorphous Na3PS4 glassy electrolytes. Our results indicate that the concentration of local structural units in the glasses impact the ionic conductivity. We found out that glasses with a relatively higher concentration of isolated PS4 and PS3 units exhibit greater Na+ ion diffusivity at temperatures below 500 K. Tuning the concentration of these structural units can be achieved through appropriate heat treatment of the amorphous Na3PS4 to achieve high ionic conductivity for novel glass-ceramic type Na3PS4 solid electrolytes at room temperature.
