  "textContent": "The present invention provides a method for manufacturing lithium titanate for a lithium secondary battery active material in which substantially no titanium dioxide, raw material, is present and which can provide excellent rapid charge and discharge characteristics and high-temperature storage characteristics to a lithium secondary battery when used as a negative electrode active material. The method for manufacturing lithium titanate for a lithium secondary battery active material according to the present invention comprises a first step of preparing a mixture comprising a Li compound, titanium dioxide having a specific surface area of 1.0 to 50.0 m/g as measured by a BET method, and one or two or more sulfates containing a metal element selected from the group consisting of Mg, Ca, and Al; a second step of pressure-molding the mixture to prepare a reaction precursor; a third step of firing the reaction precursor; and a fourth step of pulverizing the fired product by a gas-flow pulverizer to obtain lithium titanate represented by a general formula: LiTiO, having an average particle diameter of 3.0 µm or less.",
