Jm. Savariault et al., LITHIUM INSERTION STUDY IN VANADIUM-OXIDE BRONZE BY NMR AND X-RAY-DIFFRACTION, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 244, 1994, pp. 367-372
The insertion of lithium in vanadium pentoxide at high temperature is
followed both by Xray diffraction and Li-7 NMR studies. A correlation
between the lithium sites found by structure determination and the iso
tropic chemical shifts is established and a mechanism of the lithium i
nsertion proposed. Calculations of the valence of the vanadium atoms a
nd the simulation of NMR spectra allows to localise the V4+ in the hig
hest lithium rate phases.
