Abstract

The present invention relates to a method for preparing lithium titanium oxide, to lithium titanium oxide prepared by same, and to a lithium secondary battery comprising the lithium titanium oxide. The method for preparing lithium titanium oxide according to the present invention comprises the following steps: mixing raw materials for preparing lithium titanium oxide; drying the mixture; and transferring and sintering the dried mixture. The method for preparing lithium titanium oxide according to the present invention involves performing reaction, drying, and heat-treatment processes while transferring the mixture, and therefore enables a large volume of lithium titanium oxide to be prepared in a more economically advantageous manner as compared to conventional batch methods. Further, the lithium titanium oxide prepared by the consecutive reaction of the present invention may exhibit superior electrode characteristics as an electrode material as compared to lithium titanium oxide prepared by a batch reaction method.
