摘要： A method of preparing an electrode active material for manufacturing a lithium secondary battery exhibiting stable charging/discharging efficiency and life-cycle characteristics even during high-speed charging/discharging cycles is provided. Also, a method of controlling both a composition ratio (Ti/Li) of surface elements and a composition of a lithium element in a lithium titanium oxide which is known to be an electrode active material having a relatively stable structure is provided. The lithium secondary battery using the lithium titanium oxide manufactured by the method as the electrode active material can be stably used by maintaining charging/discharging efficiency and charging capacity even during the high-speed charging/discharging cycles.
