Beschreibungen/Notizen

• X-ray absorption spectroscopy has been used to characterize the structural and electronic changes induced by cycling in a CoV 2O 6/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 cobalt oxide domains embedded in a lithiated vanadium oxide matrix.
