Beschreibung
Zusammenfassung:	The present invention concerns a process to produce a high surface area iron nitride, titanium nitride, gamma-molybdenum nitride, niobium oxynitride, tantalum oxynitride, vanadium oxynitride, zirconium oxynitride, titanium oxynitride or molybdenum oxynitride coated substrate for use as an electrical energy storage component in a capacitor or a battery configuration, which process comprises: coating a substrate with a solution or slurry of the corresponding metal halide, converting the metal halide to metal oxide, and converting the metal oxide to metal nitride or oxynitride in a gaseous nitrogen atmosphere at elevated temperature.
