    Abstract: PURPOSE: A lithium titanium oxide is provided to manufacture a high-grade lithium battery by having a high purity and crystallizing property by satisfying a specific range of full width at half maximum 1 (FWHM1)/full width at half maximum 2 (FWHM2). CONSTITUTION: A lithium titanium oxide is a spinel type, and FWHM1 /FWHM2 in the range of 5-50 kHz is less than 1.70. The FWHM1 is a full width at half maximum of 7 Li peak in the range of -10 ppm to +10 ppm among a solid state-NMR spectrum of the lithium titanium oxide. The FWHM2 is a full width at half maximum of 7 Li peak in the range of -10 ppm to +10 ppm among a solid state-NMR spectrum of the lithium chloride standard reagent (STD). The FWHM1 and the FWHM2 are measured in the identical spinning rate (kHz). The manufacturing method of the lithium titanium oxide comprises the following steps. A mixture which includes a lithium-containing precursor and a titanium-containing precursor is prepared. The lithium titanium oxide is manufactured by heat treating the mixture. The titanium-containing precursor includes a second component, and the second component includes at least one of phosphorus (P) and potassium (K).
