摘要： The present invention relates to a manufacturing method of a lithium-titanium composite oxide doped with two kinds of different metals and a lithium-titanium composite oxide doped with two kinds of different metals. More particularly, the present invention relates to a manufacturing method of a lithium-titanium composite oxide doped with different metals, solid-phase mixing after adjusting a mixing ratio of two kinds of different metals and pulverizing the same, and spray drying the same to adjust contents of impurities, and a lithium-titanium composite oxide doped with different metals manufactured therefrom. By doping two kinds of different metals on the surface of the lithium-titanium composite oxide of the present invention after adjusting the ratio of the two different metals to be a desirable ratio, the present invention reduces the contents of rutile-type titanium dioxide, anatase-type titanium dioxide and Li 2 TiO 3 which have been included as impurities in the prior arts, thereby manufacturing titanium dioxide having excellent capacity characteristics and structural characteristics, and a battery including the titanium dioxide having excellent battery characteristics of high initial charge and discharge efficiency and rate capability.
