Abstract
The invention provides a low-cost, efficient method for producing lithium titanate that is useful for applications in electric storage devices. The desired lithium titanate can be obtained by heating at least (1) titanium oxide having a BET single point specific surface area of 50 to 450 m2/g based on nitrogen adsorption and (2) a lithium compound. Preferably the titanium oxide and lithium compound are heated together with (3) a lithium titanate compound having the same crystal structure as the desired lithium titanate. Preferably these ingredients are dry-mixed before heating.
