摘要
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 (Li1.81H0.19)Ti2O2H2O. The lithium titanate is preferably Li4Ti5O12 (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 TiCl4. Also, a lithium titanate obtained according to the process and a lithium battery including the lithium titanate.
