A method for preparing lithium manganate having spinel structure which comprises contacting a manganese halide and lithium compound at a temperature of 100° C. or less in a liquid phase to react with each other; a lithium manganate which is prepared according to the method, is represented by the formula LixMnOy, wherein x represents a real number satisfying 0<x<=0.8, and y represents a real number satisfying 1.8<=y<=2.4, and has an average particle diameter of 1 to 50 mum and a specific surface area of 10 to 15 m<2>/g; a positive electrode for a lithium secondary cell comprising the lithium manganate as an active material; and a lithium secondary cell using the positive electrode.
