To this aim, Sn4+-substitution of Mn could enrich the electronic properties providing during the molecular interactions of valence electrons. Within this work, electronic structure features of Sn-substituted Li2MnO3 material (Li2Mn1-xSnxO3) have been studied by the X-ray absorption fine structure (XAFS) spectroscopy calculations regarding variant x values of 0.00, 0.10, and 0.20. Higher electronegativity of the substituted Sn atom versus the host Mn atom could govern the electronic interactions via the hybridized bonds built between Sn and O atoms. The obtained results indicated that the Sn-substitution could yield better cathode properties for the Li-ion battery devices.eninfo:eu-repo/semantics/closedAccessCrystal structureElectronic structureLi-ion batteriesAbsorption spectroscopyArticle10.1016/j.mtcomm.2020.10124124Q2WOS:0005718986000112-s2.0-85085186754Q2
