- Changes in the electronic structure of V6O13 on lithium-ion insertion into battery cathod were studied by soft x-ray absorption (SXA) spectroscopy and resonant soft x-ray emission (SXE) spectroscopy. SXA and resonant SXE spectra were recorded ex situ for cycled battery cathodes discharged to different potentials corresponding closely to distinct lithiated stages (LixV6O13,x=0,1,...,6).Large systematic change were observed in the vanadium and oxygen x-ray spectra, reflecting the effects of electrochemical reduction associated with the Li-ion insertion. Spectral shape analysis indicates that a large fraction of the vanadium ions have been reduced to V3+ ions for the highest degree of, x=6. Neverrtheless, further lithiation may be possible, in view of the linear development of the vanadium and oxygen bands on charge uptake.
