    摘要: High surface area electrodes for use in electrical and electrochemical energy storage and conversion devices comprise conductive transition metal nitrides, carbides, borides or combinations thereof where the metal is molybdenum or tungsten. Disclosed is a method of manufacturing such electrodes by forming or depositing a layer of metal oxide, then exposing the metal oxide layer at elevated temperature to a source of nitrogen, carbon or boron in a chemically reducing environment to form the desired metal nitride, carbide or boride film. Also disclosed is an ultracapacitor comprised of the new high surface area electrodes having a specific capacitance of 100 mF/cm.sup.2 and an energy density of 100 mJ/cm.sup.3 with improved conductivity and chemical stability when compared to currently available electrodes.

    摘要: In accordance with an embodiment of the disclosure, a method of making a supercapacitor includes impregnating a foam electrode substrate with an active material precursor, wherein the foam electrode substrate includes a plurality of pores and the active material precursor is dispersed into the pores. The method further includes reacting the active material precursor infiltrated foam substrate with a reductant under conditions sufficient to convert the active material precursor to an active material, wherein the active material is based on a nitride, an oxynitride, a carbide, or an oxycarbide of a metal selected from Groups III, IV, V, VI, or VII of the Periodic Table.
