摘要： A method for manufacturing lithium titanate (Li4Ti5O12) of a substantially single phase, which is excellent in rate performance, and can be easily handled. The lithium titanate (Li4Ti5O12) is prepared from substantially a raw material powder consisting of a lithium compound and a raw material powder consisting of a titanic acid compound which are mixed and the resultant mixture is calcined. A lithium carbonate is used as the lithium compound and metatitanic acid or orthotitanic acid is used as the titanic acid compound. The penetration speed coefficient of the lithium titanate obtained, to a nonaqueous electrolyte is larger than a penetration speed coefficient of lithium titanate, obtained by using a lithium hydroxide as the lithium compound, to the same nonaqueous electrolyte. The specific surface area of the lithium titanate obtained is 10 m2/g or less.
