Summary: | A lithium and vanadium oxide is described having the formula Li1+xV3O8, wherein 0.1<=x<=0.25. The oxide has a monoclinic crystalline structure and comprises non-agglomerated grains in the form of monocrystalline pellets having a length L of between 1 and 100 mum, a width W such that 4<L/W<100, and a thickness t such that 4 L/t<100, with t<W, the elongation axis of the pellets being axis b of the monoclinic cell. The oxide may be prepared by mixing the Li and V precursors, without grinding or compression, heating said mixture to 565° C.-585° C. and de-agglomerating the product obtained. The oxide is suitable for use as an active material for the positive electrode of a lithium battery. |
