As one of the key components of SIBs, layered oxide cathodes have significant advantages such as high specific capacity, feasible energy density, and high operating voltage, but they also face challenges of poor interface stability and insufficient air stability. In this work, a P2/O3 biphasic system Na<sub>0.67</sub>Ni<sub>0.33</sub>Fe<sub>0.33</sub>Mn<sub>0.33</sub>O<sub>2</sub> (Na0.67NFM) is synthesized by a sol-gel and subsequent solid phase calcination method. Furthermore, the structural characteristics of Na0.67NFM calcined at 900 °C (Na0.67NFM-900) are investigated, revealing that it maintains a high stability even after exposure in humid ambient air for 5 days. Although a small amount of Na<sub>2</sub>CO<sub>3</sub> and NaHCO<sub>3</sub> is produced on the surface of Na0.67NFM-900, the main P2/O3 structure still maintains overall integrity into the internal bulk phase. Therefore, the electrochemical performance of Na0.67NFM cathode is not significantly affected after short-term air exposure. After 200 cycles at 1C, the capacity retention of Na0.67NFM-900 cathode still remains 72.3 %, which is almost comparable to that of the unexposed one (75.7 %). This work indicates that Na0.67NFM is a promising candidate cathode material with exceptional air stability for SIBs.</div></div>","PeriodicalId":431,"journal":{"name":"Solid State Ionics","volume":"426 ","pages":"Article 116895"},"PeriodicalIF":3.0,"publicationDate":"2025-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143934721","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}

Interestingly, the low-frequency pseudocapacitive analysis showed high specific capacitance at 0.2 V (emeraldine phase) and for benzoquinone and hydroquinone (intermediate phases). Complex capacitance analysis corroborates that the most capacitive potential, corresponding to emeraldine, achieved actual capacitances (C′) of 151 mF.cm<sup>−2</sup>.
