Abstract

A process for producing lithium titanate which includes the steps of synthesizing a lithium titanate hydrate intermediate via aqueous chemical processing, and thermally treating the lithium titanate hydrate intermediate to produce the lithium titanate. The lithium titanate hydrate is preferably (LiH)TiO<<2HO. The lithium titanate is preferably LiTiO(LTO). Synthesizing the lithium titanate hydrate intermediate may include mixing a titanium-containing compound with a lithium-containing compound in a solvent to produce a lithium-titanium precursor mixture. Preferably the titanium-containing compound includes titanium tetrachloride TiCl. Also, a lithium titanate obtained according to the process and a lithium battery including the lithium titanate.
