Title:
METHOD FOR PREPARING HETERO-METAL DOPED LITHIUM TITANIUM COMPLEX OXIDE AND HETERO-METAL DOPED LITHIUM TITANIUM COMPLEX OXIDE PREPARED FROM SAME
Document Type and Number:
WIPO Patent Application WO/2013/081231
Kind Code:
A1
Abstract:
The present invention relates to a method for preparing a hetero-metal doped lithium titanium complex oxide and to a hetero-metal doped lithium titanium complex oxide prepared from same, and more particularly, to a method for preparing a hetero-metal doped lithium titanium complex oxide prepared by doping a hetero-metal and spray drying and having a minutely controlled size of first particles, and to a hetero-metal doped lithium titanium complex oxide prepared from same. According to the method for preparing the hetero-metal doped lithium titanium complex oxide and to the hetero-metal doped lithium titanium complex oxide prepared from same, the size of the first particles may be minutely controlled and the growth of rutile-type titanium dioxide may be restrained, thereby providing a battery having good initial charge and discharge efficiency.
