Abstract
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 7Li 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 7Li 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.
