TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Method: The oxidation/reduction reaction between the porous carbon structure and the aqueous metal salt precursor solution occurs while the reactants are exposed to microwave energy. The cation(s) of the ionic species incorporated within the metal oxide, further comprises exchanging the cation(s) incorporated within the oxide coating for other cations or protons. The method of producing an electrode material further comprises heating the electrode material subsequent to formation of the metal oxide coating, where the heating is 70-250 degrees C as hydro thermal processing in an autoclave or where the heating is 70-1000 degrees C in inert atmosphere, oxidizing and/or reducing atmosphere. Preferred Components: The porous carbon meta-structure is formed with use of a template. The porous carbon meta-structure is formed with use of a nitrogen dopant. The oxide coating is of formula (M2O7), (M2O5), (M3O4), (MO2), (LiMO2), (LiM2O4), (Li4M5O12) or (Li28+aM20O48).
