A spherical primary particle of a lithium titanium oxide, wherein an average diameter of the spherical primary particle is about 1 to about 20 μm.
A method of preparing a spherical primary particle of a lithium oxide, the method comprising:
- mixing a lithium salt and titania to prepare a mixture;
- performing heat-treatment on the mixture at a temperature of about 700 to about 900° C.;
- and
- atomizing a resultant on which the heat-treatment is performed.
