Phase relationships in the ambient temperature LixV2O5 system (0.1<x<1.0)

Three solid phases in the ambient temperature system Li_xV₂O₅ (0.1<x<1.0) have been synthesised and characterised. Unit cell dimensions for all phases have been determined from Guinier powder X-ray analysis and are closely related to those of the parent oxide V₂O₅. An open circuit voltage vs. x plot suggests the following ranges of homogeneity - phase I 0<x<0.1, phase II 0.35<x<0.5, phase III 0.9<x<1.0.
