## Abstract

A method for forming an adherent metal based nanoparticle material layer upon a substrate includes an electrophoretic deposition method for depositing a metal nanoparticle material layer upon the substrate. The metal nanoparticle material layer may then be treated to form the adherent metal based nanoparticle material layer comprising a material selected from the group consisting of a metal oxide material, a metal nitride material, a metal oxynitride material and a metal chalcogenide material. The method is particularly useful for fabricating a battery electrode comprising a Co3O4 nanoparticle material layer, for use within a lithium ion battery. Other applications include fuel cells, capacitors and catalytic reactors.
