Structural and Electrochemical Investigation of Lithium Insertion into a New Vanadium-Oxide, V6O14
A new form of vanadium oxide with the formula V6O14 has been synthesized in aqueous media from the parent material V6O13. The material was characterized by X-ray diffraction, thermal and chemical analysis. After dehydration, the material was found to be isostructural to V6O13. Electrochemical measurements conducted in half cells with V6O14 as the cathode material and lithium metal as the anode show that this material exhibits the same features as its parent compound. Due to the higher average oxidation state of vanadium, a 10% increase in specific capacity has been achieved over V6O13. Excellent cycling capabilities are also demonstrated.
