1. A method for the production of a calcined carbon-containing lithium titanium oxide-containing spherical particle aggregates with a diameter of from 1 to 80 μm, comprising the steps of:
(a) mixing (1) a lithium salt, LiOH or Li2O, (2) a titanium oxide and (3) a carbon-containing compound in a solvent; (b) drying the mixture from step a); and (c) calcining the dried mixture, wherein the drying is carried out as spray drying.
