This work reports the amorphous SiO_x preparation via solvothermal reduction of SiCl₄ by Mg in tetrahydrofuran (THF) or dimethoxyethane (DME) solvents followed by annealing. We provide insights into the synthesis mechanism and solvent role. MgCl₂ is readily dissolved in THF, but not in DME where MgCl₂ remains bound to SiO_x particles. Hydration of MgCl₂ contributes to the SiO_x oxidation degree during washing. Thus, the solvent ability to dissolve and eliminate MgCl₂ by-product during the synthesis affects the сhemical composition and properties of SiO_x. The SiO_x–THF is less oxidized during washing compared with the SiO_x–DME. The electrochemical properties of SiO_x materials depend on their stoichiometry, which may be adjusted by the solvent used in the synthesis. The O/Si ratio increase in SiO_x decreases the reversible capacity and initial Coulombic efficiency but improves the cycling stability.</div></div>","PeriodicalId":18265,"journal":{"name":"Materials Research Bulletin","volume":"192 ","pages":"Article 113613"},"PeriodicalIF":5.3,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144271724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
