Title:
PREPARATION METHOD OF LITHIUM TITANIUM COMPOSITE OXIDE DOPED WITH DISSIMILAR METAL, AND LITHIUM TITANIUM COMPOSITE OXIDE DOPED WITH DISSIMILAR METAL PREPARED THEREBY
Document Type and Number:
WIPO Patent Application WO/2013/081418
Kind Code:
A1
Abstract:
The present invention relates to a preparation method of a lithium titanium composite oxide doped with a dissimilar metal, and a lithium titanium composite oxide doped with a dissimilar metal prepared thereby, and more specifically, to a preparation method of a lithium titanium composite oxide doped with a dissimilar metal in which the size of primary particles is finely controlled by doping a dissimilar metal and using a spray drying method, and a lithium titanium composite oxide doped with a dissimilar metal prepared thereby. According to the present invention, the preparation method of a lithium titanium composite oxide doped with a dissimilar metal, and the lithium titanium composite oxide doped with a dissimilar metal prepared thereby allow the size of primary particles to be finely controlled compared with conventional lithium titanium composite oxides, and inhibit the generation of rutile titanium oxide, thereby providing a battery with high initial charge/discharge efficiency and rate capability.
