Abstract

Vanadium oxide/polypyrrole hybrid gels were synthesized by two different strategies. These approaches were focused on either the sequential or consecutive polymerization of the inorganic and organic networks. Both techniques led to monolithic hybrid aerogels. Aerogels synthesized by the consecutive network formation method (“cosynthesis”) with compositions of approximately [PPy]0.8V205intercalated nearly twice as much Li per V2O5(2·8·3·0 Li/V205) as non-hybridized V20, aerogel (1·5 Li/V205). When suitable oxidation and polymerization treatments were applied to the materials, their specific capacity remained reasonably high (180−190 mAh/g compared to 220 mAh/g exhibited by V205, aerogel).
