Transition metal carbide or nitride or boride based supercapacitors with metal foam electrode substrate

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.
