摘要
The present invention relates to a method for manufacturing a lithium-titanium composite oxide doped by two types of metal, and to a lithium-titanium composite oxide doped by two types of metal manufactured by the same. More specifically, two types of metal are mixed at an adjusted ratio and in a solid phase, ground, sprayed, and dried. Therefore, impurity content can be adjusted. According to the present invention, two types of metal at a properly adjusted mixing ratio are doped on the surface of the lithium-titanium composite oxide. Therefore, titanium dioxide having excellent content properties and structural properties can be manufactured by reducing content of titanium dioxide in a rutile phase, titanium dioxide in an anatase phase, and Li_2Tio_3. A battery including the titanium dioxide of the present invention has excellent efficiency and a high rate of initial electricity charge and discharge.
