Recently, there has been considerable interest in advanced materials and processing techniques for practical applications. V{sub 2}O{sub 5} xerogels have generated much attention because they are layered materials that undergo reversible redox intercalation with lithium. The sol-gel process has been used to intercalate V{sub 2}O{sub 5} xerogels with the polymer electrolyte, oxymethylene linked poly(ethylene oxide)-lithium triflate[(a-PEO){sub n}(LiCF{sub 3}SO{sub 3})]. The resulting nanocomposite is a mixed ionic-electronic conductor in which the ionic charge carriers in the polymer electrolyte are in intimate contact with the electronic charge carriers in the V{sub 2}O{sub 5} xerogel. Variable-temperature electronic conductivity and thermoelectric power measurements have been performed to examine the charge transport properties.
