ABSTRACT:
A process is provided for making lithium titanate of closely controlled particle size in the range 5 nm to 2000 nm. The process includes re-firing lithium titanate under controlled conditions so that crystallites of the desired particle size are grown. The lithium titanate may be derived from any suitable source. A suitable source of lithium titanate can be from a process that includes evaporation of a blend that contains lithium and titanium to form a mixture containing lithium and titanium compounds that are subsequently calcined to form lithium titanate. The blend of titanium and lithium may be derived from a variety of titanium and lithium precursor materials.
