Title: Communication—Sol-Gel Synthesized Magnesium Vanadium Oxide, Mg x V 2 O 5 · nH 2 O: The Role of Structural Mg 2+ on Battery Performance

Abstract

Magnesium intercalated vanadium oxide xerogels, Mg0.1V2O5 · 2.35H2O and Mg0.2V2O5 · 2.46H2O were synthesized using an ion removal sol gel strategy. X-ray diffraction indicated lamellar ordering with turbostratic character. X-ray absorption spectroscopy indicated greater distortion of the vanadium-oxygen coordination environment in Mg0.2V2O5 · 2.46H2O. Elemental analysis after cycling in Li+ or Mg2+ based electrolytes revealed that the magnesium content was unchanged, indicating structural Mg2+ are retained. Furthermore, the Mg0.1V2O5 · 2.35H2O material displayed high voltage, energy density, and discharge/charge efficiency, indicating promise as a cathode material for future magnesium based batteries.
