Abstract
A composite oxide with x wt.—parts LiTiO, preferably in its cubic modification of space group Fm-3m, y wt.—parts TiO, z wt.—parts of LiCOor LiOH, u wt.—parts of a carbon source and optionally v wt.—parts of a transition or main group metal compound and/or a sulphur containing compound, wherein x is between 2 and 3, y is between 3 and 4, z is between 0.001 and 1, u is between 0.05 and 1 and 0≤v<0.1 and the metal of the transition or main group metal compound is selected from Al, Mg, Ga, Fe, Co, Sc, Y, Mn, Ni, Cr, V or mixtures thereof. Also, a process for the preparation of a composition of non-doped and doped lithium titanate LiTiO, including secondary agglomerates of primary particles, using the composite oxide and its use as anode material in secondary lithium-ion batteries.
