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.
