Abstract
A method for preparing a niobium, titanium or vanadium metal oxide nanostructured material is provided. The method comprises providing an aqueous reagent comprising (i) a soluble metal oxalate, and/or (ii) oxalic acid and a metal oxide precursor, adding a buffering agent to the aqueous reagent to form a mixture, and heating the mixture under hydrothermal conditions to obtain the metal oxide nanostructured material. The metal oxide nanostructured material may also be doped with a dopant metal such as titanium to enhance capacity and cycling stability. An electrode comprising the metal oxide nanostructured material, and an electrochemical cell containing the electrode are also provided.
