This invention provides the manufacturing method of the lithium manganate particle powder which is high output and excellent in high temperature stability. In the manufacturing method of the lithium manganate particle powder of the present invention is a method of producing a lithium manganate particle powder by mixing a lithium compound, a manganese compound and a boron compound, and then calcined at a temperature range of 800 ℃ to 1050 ℃, the boron compound that the average particle diameter (D 50) less than or equal to 15 times the average particle diameter (D 50) of the manganese compound, and characterized in, the general formula: Li 1 + x Mn 2 -x- y Y1 y O 4 + B (Y1 = Ni, Co , Mg, Fe, Al, Cr, Ti, at least one of 0.03≤x≤0.15, 0≤y≤0.20). |
