LITHIUM TITANATE HYDRATE AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To efficiently produce lithium titanate hydrate excellent in crystallinity by reacting a titanic acid compound obtained by reacting a titanium compound with an ammonium compound in water with a lithium compound in water. SOLUTION: A titanium compound is reacted with an ammonium compound in water at 0-50 deg.C to afford a titanic acid compound. Then, the titanic acid compound is reacted with a lithium compound, as necessary, in water containing 0.01-5mol/l ammonium compound at 50 deg.C to provide flaky or plate-like lithium titanate having laminate structure with 1-300m<2> /g specific surface area and 0.1-50μm longest particle diameter.
