1. A method of producing a nanofiber mat suitable for use in an electrode of a battery from a solution of metal oxide precursor and carbon-containing polymer, comprising steps of:
electrospinning the solution of metal oxide precursor into nanofibers to form a mat;
heating the mat at a temperature in a range of from 750° C. to 1100° C. for a period of from about 4 hours to about 7 hours in an absence of oxygen under a nitrogen flow to produce the nanofiber mat, and
wherein the metal oxide precursor is selected from the group consisting of titanium isopropoxide Ti{OCH(CH3)2}4, niobium ethoxide Nb2(OC2H5)10, vanadyl acetylacetonate C10H14O5V, iron acetylacetonate Fe(C5H7O2)3, manganese (II) acetate tetrahydrate, and Mn(CH3COO)2,(H2O)n, where n is a non-negative integer.
