In principle, vanadium pentoxide can be used as an active material for positive electrodes in rechargeable lithium cells. Cyclability is possible when the discharge is limited to a value of y = 2.35 (in Li,V,O,). The cycling behaviour is comparatively good up to a discharge level of y = 1.
The oxidation potentials, E,,, of several solutions of interest for nonaqueous Li cells have been measured by linear sweep voltammetric experiments. A correlation is found between E,, and the basicity of the solvents, expressed by their donor numbers (DN). Esters and sulfones have higher resistance
