Abstract
Vanadium pentoxide aerogels are pillared nanocomposites with exceptional st ability, intercalation capacity, and reversibility. X-ray absorption spectr oscopy (XAS) measurements on pristine and doped materials have revealed det ails of the oxidation state and local structure of the host material and of the polyvalent doping species. XANES measurements at the Cu K-edge for Cu- 0.1 V2O5 show the atomic level reversibility of the structure upon Li+ inse rtion/release cycling. (C) 2001 Elsevier Science B.V. All rights reserved.
