Abstract
The investigation of electrode materials based on Li-V2O5/MoO3 was performed by V Lα soft X-ray emission, V K-absorption, and photoelectron spectroscopies. During the discharge process lithium is inserted into the electrodes accompanied by a surface enrichment of LiO− groups. As the X-ray absorption spectrum obtained by excitation with synchrotron radiation, the emission band recorded with a laboratory spectrometer is also sensitive to reduction processes of the vanadium atom and to changes of bond lengths in the first coordination sphere.
