Beschreibung
Zusammenfassung:The present invention relates to a lithium-titanium complex oxide used in an electrode active material. A preparation method of a lithium-titanium complex oxide according to the present invention comprises the steps of: preparing a slurry mixture in which a titanium oxide, lithium and zirconium are mixed; wet-milling the mixture using beads having a size of 0.30 mm or less to obtain a wet-milled mixture; spray drying the wet-milled mixture to obtain a spray dried mixture; and calcining the spray dried mixture.
