A Novel Silver Molybdenum Oxyfluoride Perovskite as a Cathode Material for Lithium Batteries

Abstract

Novel electroactive nanostructured silver molybdenum oxyfluoride (SMOF) perovskites Ag1+3Mo6+(O3F3) have been successfully synthesized by a mechanochemical reaction. The formation of this perovskite was investigated throughout the Ag−Mo composition range with the use of either Ag1+ or Ag2+ in the form of AgF and AgF2 as the reactant, respectively. The compositional study combined with X-ray diffraction and extensive Raman investigation was utilized to determine structure and cation distribution and infer oxidation state. Finally, preliminary electrochemical characterization of the perovskites vs lithium was investigated.
