Abstract: The present invention relates to a composite oxide with x wt.-parts Li2TiO3, preferably in its cubic modification of space group Fm-3m, t wt.-parts TiO2, z wt.-parts of Li2CO3 or 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 a number between 2 and 3, y is a number between 3 and 4, z is a number between 0.001 and 1, u is a number 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. Further the present invention relates to the use of the composite oxide in a process for the preparation of a composition of a non-doped and doped lithium titianate Li4Ti5O12 comprising secondary agglomerates of primary particles and its use as anode material in secondary lithium-ion batteries.
