Abstract
A nanofiber mat comprises metal oxide nanoparticles distributed on surface of metal oxide nanofibers, wherein the nanofiber mat has a surface area at least 150 m2/g, and the metal oxide is selected from titanium monoxide TiOx, wherein 0.65<x<1.25, niobium monoxide NbOx, wherein 0.982<x<1.008, vanadium (II) oxide VOx, wherein 0.79 <x <1.29, iron (II) oxide FexO, wherein 0.833<x<0.957, manganese (II) oxide MnxO, wherein 0.848<x<1.000, titanium suboxide, TiOnO2n−1, wherein n>1, molybdenum suboxide, MonO3n−1, wherein n>1, MonO3n−2, wherein n>1, and vanadium suboxide, VnO2n−1, wherein n>1. Cathodes, anodes and batteries are made using the nanofiber mat. Processes for producing the metal oxide nanofiber mat and an electrode including it are also provided.
