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.The preparation method according to the present invention has an effect that the particle sizes can be adjusted through the milling process by controlling particle sizes of the precursor slurry through wet-milling.
