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

摘要

Novel electroactive nanostractured silver molybdenum oxyfluoride (SMOF) perovskites Ag_3~(1+)-Mo~(6+)(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 Ag~(1+) or Ag~(2+) 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.
