Lithium titanium oxide, method of preparing the same, negative electrode including the same, and lithium battery including the negative electrode

摘要

A lithium titanium oxide spinel having a ratio of FWHM1/FWHM2 at a spinning rate of about 5 kHz to about 50 kHz of about 1.70 or less, wherein FWHM1 is a full width at half maximum of a 7 Li peak present about -10 parts per million to about +10 parts per million in a solid state nuclear magnetic resonance spectrum of the lithium titanium oxide, FWHM2 is a full width at half maximum of a 7 Li peak present about -10 parts per million to about +10 parts per million in a solid state nuclear magnetic resonance spectrum of a lithium chloride standard reagent, and FWHM1 and FWHM2 are measured at the same spinning rate.
