Abstract

The present invention provides a nanostructured metal oxide material for use as a component of an electrode in a sodium-ion battery. The material comprises a nanostructured titanium oxide film on a metal foil substrate, which can be produced by depositing or forming a nanostructured titanium dioxide material on the substrate, and then, optionally, charging and discharging the material in an electrochemical cell to improve the capacity and Coulombic efficiency thereof.
