Abstract
X-ray absorption spectroscopy has been used to characterize the structural
and electronic changes induced by cycling in a CoV2O6/Li battery. The XANES
and EXAFS spectra recorded at both vanadium and cobalt K-edges show that a
demixion of the starting compound occurs during cycling leading to a cobal
t oxide domains embedded in a lithiated vanadium oxide matrix. (C) 2001 Els
